Brain Communication Lab
Machine-translated · View original
A lab that uses EEG to explore the mechanisms of communication between people.
AboutAbout the lab
Understanding communication through how the brain works.
The Brain Communication Lab studies human communication by combining a variety of methods, centered on experiments in cognitive neuroscience.
Its research rests on three pillars: exchanges within the brain, exchanges between people, and new kinds of exchanges between people and objects.
Using EEG experiments and mathematical modeling, the lab investigates brain networks involved in memory and emotion.
Key terms
- EEG (electroencephalography)
- A recording, made from outside the head, of the electrical changes that accompany neural activity in the brain, expressed as rhythms.
- Phase synchronization
- A phenomenon in which the timing of wave cycles aligns between different EEG rhythms or between different brain regions.
- Transcranial magnetic stimulation (TMS)
- A device or method that uses magnetic fields to stimulate the brain from outside the head.
ResearchResearch themes
The lab studies communication in three settings (within the human brain, between people, and between people and objects), centered on cognitive neuroscience experiments. It combines multiple methods, such as EEG recording and transcranial magnetic stimulation.
EEG Rhythm Synchronization, Memory, and Emotion
Using EEG experiments and mathematical modeling, the lab investigates brain networks involved in memory and emotion. It has shown the importance of phase synchronization between EEG rhythms of different frequencies, such as theta and alpha waves, and between brain regions.
*Illustrative imageInformation Flow Between Brain Regions
Using transcranial magnetic stimulation, the lab examines how the phase reset of EEG rhythms propagates through the brain. It also applies information theory to try to identify causal relationships between brain regions within a network.
*Illustrative imageBrains That Synchronize Between People
The aim is to understand the brain mechanisms underlying communication between people. The lab has shown that when two people's behavioral rhythms synchronize, whether consciously or unconsciously, their EEG rhythms synchronize as well.
*Illustrative imageExperiments on the Characteristics of Developmental Disorders
The lab conducts experiments with people with developmental disorders, who are said to have difficulty with communication, and identifies differences in behavior from neurotypical people and the accompanying differences in brain activity. It also attempts to propose objective diagnostic methods for developmental disorders.
