Title: BIAL Grants
Start date: 1994
History:
In 1994 the BIAL Foundation launched a programme of science research grants with the aim of encouraging the research into Man’s physical and mental processes, namely in fields still largely unexplored but which warrant further scientific analysis, as Psychophysiology and Parapsychology.
Since its launch, applications to the BIAL grants have been increasing. Up to now 461 projects have been supported, involving more than 1000 researchers from 27 countries.
The approved applications have benefited from grants in amounts comprised between €5,000 and €50, 000. The amount to be granted is fixed by the Scientific board according to the needs of each project.
The supported projects have originated, until April 2013, in about 600 full papers, 172 out of which were published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Among the BIAL Foundation fellows is worth highlighting the presence of scientists from prestigious universities from the United States, United Kingdom, Australia, Russia, Germany, Japan, France, Canada, and many others.

Abnormal N1/P1 responses in children with ASD elicited by both low and high spatial frequency gratings

Abstract/Results: ABSTRACT:
BACKGROUND:
It has been suggested that individuals with autistic spectrum disorder (ASD) may display abnormalities in low level visual perception.
Objectives: To investigate low level visual perception in ASD by measuring visual evoked potentials elicited by a range of spatial frequency gratings.
METHODS:
High density visual evoked potentials were recorded from children and adolescents (aged between 9 and 18) diagnosed with ASD, and chronological and nonverbal mental age matched typically developing controls in response to sinusoidal gratings presented at 0.5, 1, 4 and 8 cycles per degree (cpd). The stimuli, which measured 7.5º x 7.5º of visual angle, were presented foveally and were visible for 500 msec.
RESULTS:
Analysis of EEG data at occipital leads indicated that the controls exhibited a typical N1 / P1 complex, with a clear N1 emerging between 80 and 95 msec in response to the higher frequency stimuli (4 and 8 cpd), and a P1 which increased in latency and decreased in amplitude with increasing spatial frequency. The ASD group however did not show a clear N1, and showed reduced P1 amplitude compared to the controls, at all four spatial frequencies.
CONCLUSION:
These data suggest that early perceptual mechanisms, across a range of spatial frequencies, are abnormal in children with autistic spectrum disorder.

Fluctuations in neuronal synchronization in brain activity correlate with the subjective experience of visual recognition
Publication year: 2007
URL:
http://link.springer.com/article/10.1007%2Fs10867-007-9041-4
Abstract/Results: ABSTRACT:
The scientific study of subjective experience is a current major research area in the neurosciences. Coordination patterns of brain activity are being studied to address the question of how brain function relates to behaviour, and particularly methods to estimate neuronal synchronization can unravel the spatio-temporal dynamics of the transient formation of neuronal assemblies. We report here a biophysical correlate of subjective experience. Subjects visualised figures with different levels of noise, while their brain activity was recorded using magnetoencephalography (MEG), and reported the moment in time (corresponding to a noise level) of figure recognition, which varied between individuals, as well as the moment when they saw the figure more clearly, which was mostly common among the participants (thus less subjective). This latter moment is considered to represent psychophysical stochastic resonance (PSR). Fluctuations in neuronal synchronization, quantified using a diffusion coefficient, were lower in occipital cortex when subjects recognised the figure, for a certain noise level, but did not correlate with the moment of PSR. A different pattern was observed in frontal cortex, where lower values of the diffusion coefficient in neuronal synchronization was maintained from the moment of recognition to the moment of PSR. No specific pattern was found analysing signals from temporal or parietal cortical areas. These observations provide support for distinct synchronization patterns in different cortical areas, and represent another demonstration that the subjective, first-person perspective is accessible to scientific methods.

Visual event-related potentials in healthy infants
Publication year: 2012

Abstract/Results: ABSTRACT:
INTRODUCTION:
A large amount of research in the developmental domain has focused its attention in the newborns’ behavioral analysis. More recently, electrophysiological measures studies, such as ERPs studies, have been used to extend our knowledge about these behavioral data by learning the cerebral processes for normal as well as aberrant development (Karrer, 1998). Indeed, visual event
-related potentials (VERPs) studies with infants, at an early stage, have been proposed to be important markers in early diagnosis of sensorial deprivation (Benavente, Tamargo, Tajada, Yuste & Oliván, 2005). Studies comparing healthy newborns and newborns with different pathological diagnosis (i.e., perinatal asphyxia or intraventricular hemorrhage) showed that the VERPs components were different, namely that healthy infants presented more early components, such as N1, P2 and N3 (Kraemer, Abrahamsson & Sjostrom, 1999; Toru & Watanabe, 2006). Therefore, the objective of the present study is to understand and identify the VERPs components to different intensity visual stimuli in healthy infants.
METHOD:
Sixty-one newborns were recruited, thirteen families came to the hospital and thirteen infants were assessed. All infants were full-term, with birth weights ranging from 2620 to 4270g and had normal Apgar scores. The data for one baby was lost due to technical problems. VERP data for twelve caucasian infants with ages ranging from 23 to 41 days were recorded. Study objectives and procedures were described to parents and informed consent was obtained. When they arrived, the newborn was placed in their mother’s lap and the researcher offered white flashes holding the lamp of a Grass PS33-Plus (Astro-Med Inc.) flash stimulator, positioned at 20 cm distance from the infant and directed towards their eyes. The stimulus was offered in three different intensities. Data was recorded using a QuickAmp amplifier linked to a 32 channels ActiCap and Vision Recorder 1.10 Software (Brain Products, Brainvision Inc.).
RESULTS AND CONCLUSIONS:
All the infants showed visual evoked responses and isual ERPs components were identified. This knowledge can help professionals to make early diagnosis and adjust more direct and appropriate treatment plans for infants with sensorial processing difficulties.

Abstract/Results: RESULTS:
We developed several neural network models based on dendritic computation. Dendrites as independent computational units enable simulation of a wide variety of perceptual and cognitive phenomena. Computer simulations showed that new neural networks with dendrites are able to explain how neural activity is modulated by attention in primary visual cortex and in extra-striate cortex. Also it was shown how visual search is performed among moving targets and for targets that change locations due to the eye movements. The model of the interaction between dorsal and ventral visual streams enabled simulation of classical Gestalt principles of figure-ground organization (size, contrast, and convexity) along with newly discovered principles such as lower region and top-bottom polarity. The same model of figure-ground organization produced brain activation consistent with brain imaging studies and with electrophysiological recordings in the monkey brain. The model of temporal grouping is able to explain how we segregate figures from background based on temporal changes alone. This model does not require neural synchronization in order to sense temporal patterns. Furthermore, we developed a neural model of semantic memory which is able to simulate recent experimental findings about interaction between language understanding and perception and action. We performed several cognitive experiments which showed that perceptual and motor variables facilitate semantic processing in agreement with the model. Our project provided computational evidence for the importance of dendrites for information processing in the nervous system and for understanding visual perception and cognition.

Abstract/Results: ABSTRACT:
We proposed a neural network model in order to explain how bottom-up and top-down influences are combined into a unified perception of figure and background. Computer simulations showed that the model correctly assign figural status to familiar object when bottom-up cues are ambiguous, but when strong bottom-up cue is present, familiarity competes with it.

Abstract/Results: ABSTRACT:
Figure-ground organization is an important early step in visual processing. It separates structured input to which processing efforts should be devoted (figure) from less structured background. Gestalt psychologists identified several variables which influence figure-ground assignment, including size, contrast, surroundness, and convexity, symmetry, parallelism and horizontal-vertical axes. Recently, several new factors affecting figure-ground organization were discovered. Those are lower region, top-bottom polarity, and extremal edges. Early neurophysiological investigations of figure-ground assignment found enhanced firing rate in the primary visual cortex of monkeys. Activity enhancement was observed in the region which corresponds to the perceived figure in texture segregation task. On the other hand, recent investigations revealed a special group of neurons in the visual cortex which detect border ownership. The figure is distinguished from the background by different responses to the same boundary. If the figure is on one side of the boundary, a certain neuron will fire, but if the figure is on the other side of the same boundary, the same neuron will be silenced and another neuron will show an enhanced firing rate. There are many computational models proposed to explain the properties of figure-ground organization. Several models focused on the boundary assignment alone. Other models are concerned with explaining psychophysical findings. Although the models share some common assumptions, there are also important differences between them. Border ownership models could not explain many of the identified Gestalt principles of figural assignment. On the other hand, psychophysical models are based on the assumptions that are not supported by the neurophysiology. Important problem for the future research is how to reconcile psychophysical and neurophysiological models in order to provide a unified account of the figure-ground organization.

Abstract/Results: ABSTRACT:
Event related potential studies can provide important insights into the understanding of how and when the human brain differentiates between visual stimulus categories. Here, we ask the question whether ERP components related to object recognition show category specific responses. Many studies have concluded that faces elicit such category specific responses, based on the demonstration of a ‘face-specific’ negative ERP potential termed the ‘N170’, which is more pronounced for faces than for other visual stimuli. In the present study (8 participants), using static stimuli (photographs of faces and chairs and mooney faces) and manipulating their salience by different levels of masking, we found that the amplitude of the N170 could be modulated by the salience of the stimuli. Hence, whether the N170 for faces was larger than for non-faces simply depended on the salience level of the stimuli. Additionally, using structure-from-motion (SFM) defined face and chair stimuli, we found an object-related negative peak at 250 ms whose amplitude could be modulated by varying depth of the respective stimulus categories (‘flattening’ the stimuli leading to increasingly smaller amplitudes). Moreover, a comparison between stimulus categories (faces, chairs and coherent 2D and 3D motion) revealed that the N250 peak has a significantly larger amplitude for SFM chair stimuli than for SFM face stimuli (even for normal/optimized depth values in the two categories) and hence failed to show a face-specific effect. The object-sensitive N250 elicited by the SFM stimuli peaked around 80 ms later compared to the N170 in the static face condition, which can be well explained by a perceptual delay in perceiving SFM stimuli, i.e. the time needed in order to detect an object from the moving dot pattern. We therefore speculate that the N250 we found for SFM stimuli is a perceptual analogue of the N170 for static faces. Support for this claim comes from our finding that the N170 for static faces/chairs can also be shifted depending on the exact time of their presentation (in an experimental condition in which static stimuli become detectable later in the stimulus period, simulating the SFM condition). Taken together, these findings demonstrate a strong dependence of object-related ERP signals on depth/salience of the respective stimulus category and a lack of an unambiguous relationship between the amplitude of object-sensitive ERP components and object categories.

Abstract/Results: ABSTRACT:
OBJECTIVE:
Objective of the proposed project is to develop and test new neural networks for visual perception and cognition, which includes dendrites as independent computational units. It is expected that the neural model with dendrites will exhibit greater capacity for information processing and its output will show greater similarity with human behavior and experience compared to previous models.
METHOD:
We used computer simulations in order to test the properties of the proposed models. Results of computer simulations are compared with the results obtained in previous brain imaging and behavioral research on humans and/or neurophysiological studies on primates. Also, we tested several predictions derived from the models using cognitive experiments on humans where we measured the speed and accuracy of responses to simple perceptual and cognitive tasks.
RESULTS AND CONCLUSIONS:
Computer simulations showed that new neural networks with dendrites are able to explain how attention influences neural activity in the visual cortex, how visual search is performed, how cortical activity gives rise to figure-ground organization and perception of temporal structure. Furthermore, we developed a neural model of semantic memory which is able to simulate recent experimental findings about interaction between language understanding and perception and action. We performed several cognitive experiments which showed that perceptual and motor variables facilitate semantic processing in agreement with the model. Our project provided computational evidence for the importance of dendrites for information processing in the nervous system and for understanding visual perception and cognition.

Abstract/Results: ABSTRACT:
Objectives: This study aimed to (1) determine if fractal dimension represented a cue which maps
onto some basic human desires: a healthy environment, the presence of water, and a sense of
spirituality; (2) understand relationships between the fractal dimension of visual scenes, human
physiological responses to such scenes and self-reported preference for a visual environment.
Method: In Phase 1, fractal dimension of the treeline/sky silhouette was calculated for images in 3
categories: depth of underground water levels, (ii) perception of the site as being sacred or
secular, and (iii) the surveyed biodiversity (species richness) of the areas within which an image
was taken. In Phase 2, 50 unselected participants viewed and preference-ranked sets of images
from the 3 categories while their skin conductance responses (SCR) were recorded.
Results: Phase 1 showed no significant difference between “sacred” vs “secular” sites and fractal
dimension (W=174, N=40, p=0.25). Differences for water-depth were close to significance (shallow
vs deep : W=23, N=18, p=0.07) and for biodiversity sites were significant (high vs low: W=25, N=40,
p=1.34x10-7). Phase 2 showed a significant negative relationship (r = -0.11, p = 0.03) between
participant SCR magnitude and fractal dimension, and a positive correlation between expressed
preference and fractal dimension (rho = 0.61, p= 0.03).
Conclusions: Results support the idea that visual complexity of a scene (known to influence
preference) relates both to useful information about a site (water depth and biodiversity) and to
our level of arousal upon seeing that site.
Discussion: This study gives the first supporting evidence for the idea that humans have an ability
to recognise and prefer environments that are ecologically healthy (biodiverse and having a nearto-
surface water table). As water depth showed a negative correlation to fractal dimension, which
showed a negative correlation related to skin conductance response, near-to-surface water should
show a relaxation response that could be expressed via ideomotor action, suggesting that visual
factors in dowsing studies might be a useful area to pursue.

The dual facet of gamma oscillations: Separate visual and decision making circuits as revealed by simultaneous EEG/fMRI
Publication year: 2014

http://onlinelibrary.wiley.com/doi/10.1002/hbm.22545/abstract
Abstract/Results: ABSTRACT:
It remains an outstanding question whether gamma-band oscillations reflect unitary cognitive processes within the same task. EEG/MEG studies do lack the resolution or coverage to address the highly debated question whether single gamma activity patterns are linked with multiple cognitive modules or alternatively each pattern associates with a specific cognitive module, within the same coherent perceptual task. One way to disentangle these issues would be to provide direct identification of their sources, by combining different techniques. Here, we directly examined these questions by performing simultaneous EEG/fMRI using an ambiguous perception paradigm requiring holistic integration. We found that distinct gamma frequency sub-bands reflect different neural substrates and cognitive mechanisms when comparing object perception states vs. no categorical perception. A low gamma sub-band (near 40 Hz) activity was tightly related to the decision making network, and in particular the anterior insula. A high gamma sub-band (~60 Hz) could be linked to early visual processing regions. The demonstration of a clear functional topography for distinct gamma sub-bands within the same task shows that distinct gamma-band modulations underlie sensory processing and perceptual decision mechanisms.

Functional reorganization of the visual dorsal stream as probed by 3-D visual coherence in Williams syndrome

Abstract/Results: ABSTRACT:
Object and depth perception from motion cues involves the recruitment of visual dorsal stream brain areas. In 3-D structure-from-motion (SFM) perception, motion and depth information are first extracted in this visual stream to allow object categorization, which is in turn mediated by the ventral visual stream. Such interplay justifies the use of SFM paradigms to understand dorsal-ventral integration of visual information. The nature of such processing is particularly interesting to be investigated in a neurological model of cognitive dissociation between dorsal (impaired) and ventral stream (relatively preserved) processing, Williams syndrome (WS). In the current fMRI study, we assessed dorsal versus ventral stream processing by using a performance-matched 3-D SFM object categorization task. We found evidence for substantial reorganization of the dorsal stream in WS as assessed by whole-brain ANOVA random effects analysis, with subtle differences in ventral activation. Dorsal reorganization was expressed by larger medial recruitment in WS (cuneus, precuneus, and retrosplenial cortex) in contrast with controls, which showed the expected dorsolateral pattern (caudal intraparietal sulcus and lateral occipital cortex). In summary, we found a substantial reorganization of dorsal stream regions in WS in response to simple visual categories and 3-D SFM perception, with less affected ventral stream. Our results corroborate the existence of a medial dorsal pathway that provides the substrate for information rerouting and reorganization in the presence of lateral dorsal stream vulnerability. This interpretation is consistent with recent findings suggesting parallel routing of information in medial and lateral parts of dorsal stream.

The approved applications have benefited from grants in amounts comprised between €5,000 and €50, 000. The amount to be granted is fixed by the Scientific board according to the needs of each project.
The supported projects have originated, until April 2013, in about 600 full papers, 172 out of which were published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Among the BIAL Foundation fellows is worth highlighting the presence of scientists from prestigious universities from the United States, United Kingdom, Australia, Russia, Germany, Japan, France, Canada, and many others.
The BIAL grants are promoted biannually.

The linear impact of concurrent working memory load on dynamics of Necker cube perceptual reversals
Publication year: 2014

Abstract/Results: ABSTRACT:
Ambiguous figures are visual stimuli that may be perceived in multistable interpretations. The role of attention in modulating perceptual reversals of ambiguous stimuli is not clear. We tested whether perceptual reversals depend on working memory by manipulating its load while the participants were viewing the Necker cube. Increasing working memory load delayed the latency and decreased the frequency of reversals. These effects followed a linear function of load. The findings imply shared resources of the mechanisms responsible for perceptual reversals and working memory maintenance. However, reversals were not completely abolished even with the hard seven-consonants load, suggesting that bottom-up processes continue to operate in the bistable perception dynamics when top-down mechanisms are attenuated.

Robust single trial identification of conscious percepts triggered by sensory events of variable saliency

Abstract/Results: ABSTRACT:
The neural correlates of visual awareness are elusive because of its fleeting nature. Here we have addressed this issue by
using single trial statistical ‘‘brain reading’’ of neurophysiological event related (ERP) signatures of conscious perception of
visual attributes with different levels of saliency. Behavioral reports were taken at every trial in 4 experiments addressing
conscious access to color, luminance, and local phase offset cues. We found that single trial neurophysiological signatures of target presence can be observed around 300 ms at central parietal sites. Such signatures are significantly related with
conscious perception, and their probability is related to sensory saliency levels. These findings identify a general neural
correlate of conscious perception at the single trial level, since conscious perception can be decoded as such independently
of stimulus salience and fluctuations of threshold levels. This approach can be generalized to successfully detect target
presence in other individuals.

The dual facet of gamma oscillations: Separate visual and decision making circuits as revealed by simultaneous EEG/fMRI
Publication year: 2014
URL:
http://onlinelibrary.wiley.com/doi/10.1002/hbm.22545/abstract
Abstract/Results: ABSTRACT:
It remains an outstanding question whether gamma-band oscillations reflect unitary cognitive processes within the same task. EEG/MEG studies do lack the resolution or coverage to address the highly debated question whether single gamma activity patterns are linked with multiple cognitive modules or alternatively each pattern associates with a specific cognitive module, within the same coherent perceptual task. One way to disentangle these issues would be to provide direct identification of their sources, by combining different techniques. Here, we directly examined these questions by performing simultaneous EEG/fMRI using an ambiguous perception paradigm requiring holistic integration. We found that distinct gamma frequency sub-bands reflect different neural substrates and cognitive mechanisms when comparing object perception states vs. no categorical perception. A low gamma sub-band (near 40 Hz) activity was tightly related to the decision making network, and in particular the anterior insula. A high gamma sub-band (~60 Hz) could be linked to early visual processing regions. The demonstration of a clear functional topography for distinct gamma sub-bands within the same task shows that distinct gamma-band modulations underlie sensory processing and perceptual decision mechanisms.

Publication year: 2014

http://fens2014.meetingxpert.net/FENS_427/poster_103791/program.aspx
Abstract/Results: ABSTRACT:
Previous studies have provided evidence for a wide variety of gamma-band patterns and sources for different tasks but not within the same type of cognitive task. Importantly, it remains unclear whether distinct patterns related to different cognitive modules coexist in the same task. Unimodal (EEG/MEG) studies do not have enough resolution to test for non-unitary sources and to establish their spatial distribution. Thus it remains an outstanding question whether gamma-band oscillations reflect unitary cognitive processes within the same task. We combined EEG with fMRI to address the highly debated question whether single gamma activity patterns are linked with multiple cognitive modules or alternatively each pattern associates with a specific cognitive module, within the same coherent perceptual task. We used an ambiguous perception paradigm requiring holistic integration. We found that distinct gamma frequency sub-bands reflect different neural substrates and cognitive mechanisms when comparing object perception states vs. no categorical perception, confirming our previous findings in a clinical model of impaired coherence, Williams Syndrome, whereby different parcellation of gamma activity patterns was identified. Accordingly, low gamma (30-48Hz) responses are related to general perceptual decision-making networks and high gamma activity (52-70Hz) with low level visual processing. These non-unitary patterns are relevant for the understanding of normal and clinical impaired holistic integration and show that current neural models of gamma activity generation need to consider their duality.

Title:
The linear impact of concurrent working memory load on dynamics of Necker cube perceptual reversals

Abstract/Results: ABSTRACT:
Ambiguous figures are visual stimuli that may be perceived in multistable interpretations. The role of attention in modulating perceptual reversals of ambiguous stimuli is not clear. We tested whether perceptual reversals depend on working memory by manipulating its load while the participants were viewing the Necker cube. Increasing working memory load delayed the latency and decreased the frequency of reversals. These effects followed a linear function of load. The findings imply shared resources of the mechanisms responsible for perceptual reversals and working memory maintenance. However, reversals were not completely abolished even with the hard seven-consonants load, suggesting that bottom-up processes continue to operate in the bistable perception dynamics when top-down mechanisms are attenuated.
