Abstract/Results: RESULTS:
Brain imaging performed during a variety of psychophysical experiments has demonstrated that specific neocortical areas change their activity when subjects are experiencing other subjects. Where in the brain self/other awareness is represented is an emerging area of investigation. We have addressed the neuronal dynamics of interpersonal interactions using simple psychophysical paradigms while recording brain activity using magnetoencephalography (MEG). We build on current concepts of brain function and propose that the coordinated (synchronized) activity in distinct cortical areas will reveal brain regions involved in "self" versus "others" processing. In general, the analysis of synchronization of cortical regions derived from the MEG recordings revealed enhanced synchronization between the activity of the midline and the prefrontal cortex,
and that the midline cortex synchronizes its activity with parietal areas as well. The pattern of synchronization was similar when study participants experienced noxious stimuli (a selfadministered painful stimulus to the fingers of the right hand) as when they were watching films of other people or animals experiencing pain. However, these synchronization patterns differed from those obtained when the participants visualised photographs of faces, themselves included. We thus conclude that midline and prefrontal cortices are important in the processing of sensory painful stimulation, and in generating empathy towards others' pain. We expect that these studies will serve as preliminary background to undertake the investigation of reflective self-awareness and its relation to interpersonal transactions.

Enhanced measured synchronization of unsynchronized sources: inspecting the physiological significance of synchronization analysis of whole brain electrophysiological recordings
Publication year: 2007
URL:
http://academicjournals.org/journal/IJPS/article-abstract/937512C13308
Abstract/Results: ABSTRACT:
The analysis of synchronization, particularly phase locking, is being increasingly used in neuroscience to explore coordinated brain activity. The application of this methodology to magnetoencephalographic (MEG) and electroencephalographic (EEG) recordings would seem promising because these two recording techniques are not invasive and have great temporal resolution. However, current methods of synchronization analysis applied directly to raw MEG/EEG data may produce distorted results. In this work we introduce a model of brain activity based on random current dipoles that reproduces the main characteristics observed in measurements of real data synchronization, even when no synchronized activity is taking place among the sources. In particular we describe the effect of field superposition alone when secondary currents are excluded. It is also shown that the enhanced local synchronization, previously described in some studies of epileptic seizures, may result from the activity of only a few unsynchronized sources. We suggest three lines of research for further development and improvement to obtain more precise physiological interpretations of the synchronization analysis.

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:
Fluctuations in phase synchrony have been characteristically found in recordings from both normal physiological brains as well as pathological ones. These fluctuations, characteristically termed as noise, are
logistically difficult to separate from true neuronal activity largely due to current recording and analysis methods. We propose that phase synchrony fluctuations serve to maintain brain activity in an optimal state for cognitive processing, thereby not allowing it to fall into long-term periodic behavior. We compared fluctuations from controls to those found in patients with epilepsy or traumatic brain injuries (TBI). Phase synchronization analysis using the Hilbert Transform was performed on magnetoencephalography (MEG) and electroencephalography (EEG) recordings from controls and patients. In the MEG study, 4 epileptic patients and 4 controls were tested. A total of 14 head-injured children and 2 controls were analyzed using scalp EEG, after performing a Laplacian Derivation. Results - Phase-locking patterns between brain areas were found to display fluctuations at different scales. Both epileptiform activity and TBI had relatively low levels of fluctuations in phase synchrony. This may contribute to the generation of synchronized states seen in patients with these brain disorders. Conclusions and Implications. Determination of phase-locking patterns and their variability in brain recordings reveals characteristics of the pathologies with which they are associated. While there is no clear distinction between noise and highdimensional dynamics, we propose that the examination of neuronal fluctuations at different levels will provide important insights into our understanding of the relationship between brain and behavior.

Dynamic brain patterns in neocortical areas during interpersonal transactions

Abstract/Results: ABSTRACT:
Brain imaging performed during a variety of psychophysical experiments has demonstrated that specific neocortical areas change their activity when subjects are experiencing other subjects. Where in the brain self/other awareness is represented is an emerging area of investigation. We have addressed the neuronal dynamics of interpersonal interactions using simple psychophysical paradigms while recording brain activity using magnetoencephalography (MEG), and analysing the patterns of neuronal synchronization.. We build on current concepts of brain function and propose that the coordinated (synchronized) activity in distinct cortical areas will reveal brain regions involved in "self" versus "others" processing. The analysis of synchronization of cortical regions derived from the MEG recordings revealed enhanced synchronization between the activity of the midline and the prefrontal cortex, and that the midline cortex synchronizes its activity with parietal areas as well. The pattern of synchronization was similar when study participants experienced noxious stimuli (a self-administered painful stimulus to the fingers of the right hand) as when they were watching films of other people or animals experiencing pain. However, these synchronization patterns differed from those obtained when the participants visualised photographs of faces, themselves included. We thus conclude that midline and prefrontal cortices are important in the processing of sensory painful stimulation and in generating empathy towards others' pain. We expect that these studies will serve as preliminary background to undertake the investigation of reflective self-awareness and its relation to interpersonal transactions.

Fluctuations in neuronal synchronization in brain activity correlate with the subjective experience of visual recognition
Publication year: 2007

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.
