Abstract/Results: ABSTRACT:
During the last decade the role of high frequency EEG activity in the ‘binding phenomenon’ was discovered. It was supposed that this phenomenon provided the integration between different brain structures underlying higher nervous functions and possibly even consciousness [Proc. Natl. Acad. Sci. 90 (1993) 2078; Annu. Rev. Neurosci. 18 (1995) 555; J. Neurosci. V 16 (1996) 4240; Am. Physiol. Soc. (1998) 1567; Induced Rhythms in the Brain (1992) 425; NeuroReport 8 (1997) 531; Proc. Natl. Acad. Sci. USA 94 (1997) 12198]. Schizophrenia is considered as a disorder of the integration between different brain regions [Review of Psychiatry 18 (1999a) 29; Conceptual Advances in Russian Neuroscience: Complex Brain Functions (1999) 151; Brain Res. Rev. 31 (2000) 301], and in the present work we have studied cortical connectivity, focusing on those connections which are maintained by high frequency EEG-rhythm (20–40 Hz). The results showed a high degree of biopotential synchronisation between definite cortical areas during cognitive processes in normal subjects and have evidenced significant functional connectivity disturbances in schizophrenia in this EEG frequency domain.

Heart cycle-related effects on event-related potentials, spectral power changes, and connectivity patterns in the human ECoG
Publication year: 2013
URL:
http://www.sciencedirect.com/science/article/pii/S1053811913005363
Abstract/Results: ABSTRACT:
The perception of one's own heartbeat is a fundamental interoceptive process that involves cortical and subcortical structures. Yet, the precise spatiotemporal neuronal activity patterns underlying the cortical information processing have remained largely elusive. Although the high temporal and spatial resolution of electrocorticographic (ECoG) recordings is increasingly being exploited in functional neuroimaging, it has not been used to study heart cycle-related effects. Here, we addressed the capacity of ECoG to characterize neuronal signals within the cardiac cycle, as well as to disentangle them from heart cycle-related artifacts. Based on topographical distribution and latency, we identified a biphasic potential within the primary somatosensory cortex, which likely constitutes a heartbeat-evoked potential (HEP) of neuronal origin. We also found two different types of artifacts: i) oscillatory potential changes with a frequency identical to the heart pulse rate, which probably represent pulsatility artifacts and ii) sharp potentials synchronized to the R-peak, corresponding to the onset of ventricular contraction and the cardiac field artifact (CFA) in EEG. Finally, we show that heart cycle-related effects induce pronounced phase-synchrony patterns in the ECoG and that this kind of correlation patterns, which may confound ECoG connectivity studies, can be reduced by a suitable correction algorithm. The present study is, to our knowledge, the first one to show a focally localized cortical HEP that could be clearly and consistently observed over subjects, suggesting a basic role of primary sensory cortex in processing of heart-related sensory inputs. We also conclude that taking into account and reducing heart cycle-related effects may be advantageous for many ECoG studies, and are of crucial importance, particularly for ECoG-based connectivity studies. Thus, in summary, although ECoG poses new challenges, it opens up new possibilities for the investigation of heartbeat-related viscerosensory processing in the human brain.

Abstract/Results: ABSTRACT:
Our main goals were to investigate the neurophysical mechanisms underlying hypnosis and to examine alterations in consciousness during hypnosis. A novelty of our project is that it investigates the neurophysiological mechanisms of hypnosis using intracranial electroencephalography (iEEG), as the majority of studies on this topic have used other non-invasive modalities. Based on the notion that the “connectivity” among brain regions is fundamental to understand how the brain manages to process information, we assess synchrony patterns and the complexity of those patterns.
A total of 18 patients participated in this study. Usable data were obtained from 11 of those patients. Hypnosis was induced and hypnotizability was assessed using a modified and extended version of the Stanford Hypnotic Susceptibility Scale. Continuous iEEG was recorded with an EEG software in the Epilepsy Unit of the Toronto Western Hospital. The hypnotic sessions were also video recorded.
On the dispute whether hypnosis is an altered state marked by a level of awareness associated with distinctive electrophysiological patterns, our preliminary results point towards a characterization of hypnosis as a state lacking an easily distinguishable pattern from other more “ordinary” mind states. The extensive network analysis here performed does not show a brain network pattern characteristic of the hypnotic condition. This result however may be affected by the limited sample (11 subjects) and the extremely challenging condition in which the practice of hypnosis was conducted in the patients at the Epilepsy Unit.

Eyes closed or eyes open? Exploring the alpha desynchronization hypothesis in resting state functional connectivity networks with intracranial EEG
Publication year: 2017

http://www.biorxiv.org/content/early/2017/03/18/118174
Abstract/Results: ABSTRACT:
This paper addresses a fundamental question, are eyes closed and eyes open resting states equivalent baseline conditions, or do they have consistently different electrophysiological signatures? We compare the functional connectivity patterns in an eyes closed resting state with an eyes open resting state, and show that functional connectivity in the alpha band decreases in the eyes open condition compared to eyes closed. This "alpha desynchronization" or reduction in the number of connections from eyes closed to eyes open, is here, for the first time, studied with intracranial recordings. We provide two calculations of the wiring cost, local and mesoscopic, defined in terms of the distance between the electrodes and the likelihood that they are functionally connected. We find that, in agreement with the "alpha desynchronization" hypothesis, the local wiring cost decreases going from eyes closed to eyes open. However, when the wiring cost calculation takes into account the connectivity pattern, the wiring cost variation from eyes closed to eyes open is not as consistent and shows regional specificity. The wiring cost measure defined here, provides a new avenue for understanding the electrophysiology of resting state.

Abstract/Results: ABSTRACT:
This research investigates the neurophysiological mechanisms of hypnosis using intracranial electroencephalography. This methodology removes resolution problems associated with functional imaging. Patients with intractable epilepsy, and implanted as part of their diagnostic exam, were hypnotized. Neutral hypnosis was measured following a standard induction procedure, and before the administration of hypnotic suggestions. Patients with high and low hypnotizability were tested and compared. Phase based synchronization for connectivity analysis was calculated for three different conditions: prehypnotic state (eyes open and closed), neutral hypnosis (eyes closed) and posthypnotic state (eyes open and closed), across multiple frequency bands. The intersite phase clustering difference between all the intracranial electrodes across delta, theta, alpha, beta and gamma frequencies, was computed for all conditions. In high hypnotizable patients with bi-temporal burr holes, we found more intersite synchronization, for theta and alpha bands, in the hypnotic condition than in the eyes closed conditions, and a more modular organization (more partitionable) in both the hypnotic and the eyes closed conditions, compared to the eyes open conditions. Phase synchronization distribution distance for all bands between hypnotic and posthypnotic states was shorter in high than in low hypnotizable patients. Our results suggest that hypnosis represents a genuine brain state whose distinctiveness from states of deep relaxation is in need of clarification.

Pivotal role of hMT+ in long-range disambiguation of interhemispheric bistable surface motion
Publication year: 2017

http://onlinelibrary.wiley.com/doi/10.1002/hbm.23701/abstract;jsessionid=B647FF44A05DF816D3295CE4E21A1540.f04t02
Abstract/Results: ABSTRACT:
It remains an open question whether long-range disambiguation of ambiguous surface motion can be achieved in early visual cortex or instead in higher level regions, which concerns object/surface segmentation/integration mechanisms. We used a bistable moving stimulus that can be perceived as a pattern comprehending both visual hemi-fields moving coherently downward or as two widely segregated nonoverlapping component objects (in each visual hemi-field) moving separately inward. This paradigm requires long-range integration across the vertical meridian leading to interhemispheric binding. Our fMRI study (n=30) revealed a close relation between activity in hMT+ and perceptual switches involving interhemispheric segregation/integration of motion signals, crucially under nonlocal conditions where components do not overlap and belong to distinct hemispheres. Higher signal changes were found in hMT+ in response to spatially segregated component (incoherent) percepts than to pattern (coherent) percepts. This did not occur in early visual cortex, unlike apparent motion, which does not entail surface segmentation. We also identified a role for top–down mechanisms in state transitions. Deconvolution analysis of switch-related changes revealed prefrontal, insula, and cingulate areas, with the right superior parietal lobule (SPL) being particularly involved. We observed that directed influences could emerge either from left or right hMT+ during bistable motion integration/segregation. SPL also exhibited significant directed functional connectivity with hMT+, during perceptual state maintenance (Granger causality analysis). Our results suggest that long-range interhemispheric binding of ambiguous motion representations mainly reflect bottom–up processes from hMT+ during perceptual state maintenance. In contrast, state transitions maybe influenced by high-level regions such as the SPL

Exploring the alpha desynchronization hypothesis in resting state networks with intracranial electroencephalography and wiring cost estimates
Publication year: 2017

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5688079/
Abstract/Results: ABSTRACT:
This paper addresses a fundamental question, are eyes closed and eyes open resting states equivalent baseline conditions, or do they have consistently different electrophysiological signatures? We compare the functional connectivity patterns in an eyes closed resting state with an eyes open resting state to investigate the alpha desynchronization hypothesis. The change in functional connectivity from eyes closed to eyes open, is here, for the first time, studied with intracranial recordings. We perform network connectivity analysis in iEEG and we find that phase-based connectivity is sensitive to the transition from eyes closed to eyes open only in interhemispheral and frontal electrodes. Power based connectivity, on the other hand, consistently discriminates between the two conditions in temporal and interhemispheral electrodes. Additionally, we provide a calculation for the wiring cost, defined in terms of the connectivity between electrodes weighted by distance. We find that the wiring cost variation from eyes closed to eyes open is sensitive to the eyes closed and eyes open conditions. We extend the standard network-based approach using the filtration method from algebraic topology which does not rely on the threshold selection problem. Both the wiring cost measure defined here and this novel methodology provide a new avenue for understanding the electrophysiology of resting state.

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.
The BIAL grants are promoted biannually.

Abstract/Results: ABSTRACT:
Transcranial electrical stimulation (tES) is a potentially viable tool for boosting cognitive performance in aging. However, most knowledge on tES effects is based on studies involving young adults. Here, we applied tES (transcranial random noise stimulation [tRNS] as an effective stimulation and anodal transcranial direct current stimulation [atDCS] as a “control” stimulation) to the visual cortex during visual perceptual learning (VPL) in healthy young and older individuals. Moreover, we measured transcranial magnetic stimulation–evoked potentials to investigate the neurophysiological underpinnings of tES effects. We found that only the tRNS in the young, but not in the older, subjects modulated VPL, by decreasing performance. Transcranial magnetic stimulation–evoked potentials revealed age-related changes in connectivity, that is, a stronger activation of the prefrontal cortex after visual cortex stimulation, and a stronger modulation of the prefrontal cortex after VPL in the older subjects. These results may indicate that task performance in older adults relies on the recruitment of a wider network and a crucial contribution of the anterior portion of the brain, which may dramatically influence tES effects in aging.

Abstract/Results: ABSTRACT:
In the first phase we tested the effects of different tES protocols in visuo-spatial contextual learning (VSCL).
The study comprised three sessions designed to evaluate tDCS-induced changes in VSCL measures collected during the execution of a visual search task widely used to examine statistical learning in the visuo-spatial domain. In Experiment1 (E1), we probed for the effects of left-posterior parietal cortex (PPC) anodal-tDCS (AtDCS) at different timings (offline and online) and intensities (3mA, 1.5mA). The protocol producing the more robust effect in E1 was used in E2 with a swapped electrodes montage, while In E3, left-PPC 3mA cathodal-tDCS (CtDCS) was applied offline and online to investigate the effects on neuronal excitability reduction on VSCL.
Results revealed that high intensity offline AtDCS reduced VSCL regardless of the stimulation side (E1 & 2), while no significant behavioural changes were produced by both online AtDCS protocols (E1) and offline/online CtDCS (E3). The reduced VSCL could result from homeostatic mechanisms produced by the interaction of two excitability-increasing events hindering normal task-related neuroplastic phenomena.
In the second phase of project, we examined the neurophysiological correlates of modified cognitive performance by 3mA anodal-tDCS offline on left-posterior parietal cortex (PPC).
We acquired various electrophysiological measures in order to fully investigate the neural modifications induced by the application of the tES protocol producing the more robust effect in the first phase of the project. Electrophysiological measures were recorded both during the execution of the behavioural task (ERP measures) and during TMS-EEG co-registration at three different intervals (before tDCS (TEP1), after tDCS but before task (TEP2) and after task (TEP3)).
ERPs revealed a significant difference in the amplitude of N1 and P3 and this modulation could be interpreted as a general memory-mediated attentional capture produced by visual contexts that were repeated over time. Interestingly, Real-tDCS also produced a strong significant increase in the amplitude of the posterior P2 component in response to both repeated and not-repeated visual contexts. This modulation could reflect a stimulation dependent reduction of perceived saliency associated with the presentation of the visual search arrays. TMS-evoked potentials show that the only application of tDCS does not produce changes in connectivity, but there is a different pattern between real and sham conditions when participants are also asked to perform a cognitive task and it improves with time. Furthermore, the difference between TEP 1 and TEP 3 in sham condition, and not in the real one, suggests a reduction of cortical activation after real stimulation.

Neural dynamics of mindfulness meditation and hypnosis explored with intracranial EEG: A feasibility study
Publication year: 2022

https://www.sciencedirect.com/science/article/abs/pii/S0304394021007242
Abstract/Results: ABSTRACT:
Purpose
Intracranial electroencephalography (iEEG) offers a unique window on brain dynamics with excellent temporal and spatial resolution and is less prone to recording artefacts than surface EEG. This study used a within-subject design to explore the feasibility to compare iEEG data during mind wandering, mindfulness meditation and hypnosis.
Results
Three patients who had iEEG for clinical monitoring and who were new to mindfulness meditation and hypnosis were able to enter these states. We found non-specific and wide-spread amplitude modulations. Data-driven connectivity analysis revealed widespread connectivity patterns that were common across the three conditions. These were predominant in the low frequencies (delta, theta and alpha) and characterised by positively correlated activity. Connectivity patterns that were unique to the three conditions predominated in the gamma band, one third of the correlations in these patterns were negative.
Conclusions
This study is the first to support the feasibility of a direct comparison of the neural correlates of mindfulness meditation and hypnosis using iEEG. These modulations may reflect the complex interplay between different known brain networks, and warrant further functional investigations in particular in the gamma band.

Abstract/Results: ABSTRACT:
What mechanisms underlie flexible inter-areal communication in the cortex? We consider four mechanisms for temporal coordination and their contributions to communication: (1) Oscillatory synchronization (communication-through-coherence); (2) communication-through-resonance; (3) non-linear integration; and (4) linear signal transmission (coherence-through-communication). We discuss major challenges for communication-through-coherence based on layer- and cell-type-specific analyses of spike phase-locking, heterogeneity of dynamics across networks and states, and computational models for selective communication. We argue that resonance and non-linear integration are viable alternative mechanisms that facilitate computation and selective communication in recurrent networks. Finally, we consider communication in relation to cortical hierarchy and critically examine the hypothesis that feedforward and feedback communication use fast (gamma) and slow (alpha/beta) frequencies, respectively. Instead, we propose that feedforward propagation of prediction errors relies on the non-linear amplification of aperiodic transients, whereas gamma and beta rhythms represent rhythmic equilibrium states that facilitate sustained and efficient information encoding and amplification of short-range feedback via resonance.

Unravelling brain connectivity patterns in body dysmorphic disorder during decision-making on visual illusions: A graph theoretical approach
Publication year: 2023

https://www.sciencedirect.com/science/article/pii/S0165178123002068
Abstract/Results: ABSTRACT:
Body dysmorphic disorder (BDD) is characterized by an excessive preoccupation with perceived defects in physical appearance, and is associated with compulsive checking. Visual illusions are illusory or distorted subjective perceptions of visual stimuli, which are induced by specific visual cues or contexts. While previous research has investigated visual processing in BDD, the decision-making processes involved in visual illusion processing remain unknown. The current study addressed this gap by investigating the brain connectivity patterns of BDD patients during decision-making about visual illusions. Thirty-six adults - 18 BDD (9 female) and 18 healthy controls (10 female) - viewed 39 visual illusions while their EEG was recorded. For each image, participants were asked to indicate (1) whether they perceived the illusory features of the images; and (2) their degree of confidence in their response. Our results did not uncover group-level differences in susceptibility to visual illusions, supporting the idea that higher-order differences, as opposed to lower-level visual impairments, can account for the visual processing differences that have previously been reported in BDD. However, the BDD group had lower confidence ratings when they reported illusory percepts, reflecting increased feelings of doubt. At the neural level, individuals with BDD showed greater theta band connectivity while making decisions about the visual illusions, likely reflecting higher intolerance to uncertainty and thus increased performance monitoring. Finally, control participants showed increased left-to-right and front-to-back directed connectivity in the alpha band, which may suggest more efficient top-down modulation of sensory areas in control participants compared to individuals with BDD. Overall, our findings are consistent with the idea that higher-order disruptions in BDD are associated with increased performance monitoring during decision-making, which may be related to constant mental rechecking of responses.

Neurophysiological Markers of Premotor–Motor Network Plasticity Predict Motor Performance in Young and Older Adults
Publication year: 2023

Abstract/Results: ABSTRACT:
Aging is commonly associated with a decline in motor control and neural plasticity. Tuning cortico–cortical interactions between premotor and motor areas is essential for controlling fine manual movements. However, whether plasticity in premotor–motor circuits predicts hand motor abilities in young and elderly humans remains unclear. Here, we administered transcranial magnetic stimulation (TMS) over the ventral premotor cortex (PMv) and primary motor cortex (M1) using the cortico–cortical paired-associative stimulation (ccPAS) protocol to manipulate the strength of PMv-to-M1 connectivity in 14 young and 14 elderly healthy adults. We assessed changes in motor-evoked potentials (MEPs) during ccPAS as an index of PMv-M1 network plasticity. We tested whether the magnitude of MEP changes might predict interindividual differences in performance in two motor tasks that rely on premotor-motor circuits, i.e., the nine-hole pegboard test and a choice reaction task. Results show lower motor performance and decreased PMv-M1 network plasticity in elderly adults. Critically, the slope of MEP changes during ccPAS accurately predicted performance at the two tasks across age groups, with larger slopes (i.e., MEP increase) predicting better motor performance at baseline in both young and elderly participants. These findings suggest that physiological indices of PMv-M1 plasticity could provide a neurophysiological marker of fine motor control across age-groups.

Title:
Evaluating brain spectral and connectivity differences between silent mind-wandering and trance states
Publication year: 2023

Abstract/Results: ABSTRACT:
Trance is an altered state of consciousness characterized by alterations in cognition. In general, trance states induce mental silence (i.e., cognitive thought reduction), and mental silence can induce trance states. Conversely, mind-wandering is the mind's propensity to stray its attention away from the task at hand and toward content irrelevant to the current moment, and its main component is inner speech. Building on the previous literature on mental silence and trance states and incorporating inverse source reconstruction advances, the study's objectives were to evaluate differences between trance and mind-wandering states using: (1) electroencephalography (EEG) power spectra at the electrode level, (2) power spectra at the area level (source reconstructed signal), and (3) EEG functional connectivity between these areas (i.e., how they interact). The relationship between subjective trance depths ratings and whole-brain connectivity during trance was also evaluated. Spectral analyses revealed increased delta and theta power in the frontal region and increased gamma in the centro-parietal region during mind-wandering, whereas trance showed increased beta and gamma power in the frontal region. Power spectra at the area level and pairwise comparisons of the connectivity between these areas demonstrated no significant difference between the two states. However, subjective trance depth ratings were inversely correlated with whole-brain connectivity in all frequency bands (i.e., deeper trance is associated with less large-scale connectivity). Trance allows one to enter mentally silent states and explore their neurophenomenological processes. Limitations and future directions are discussed.
