Psychiatric and neurodevelopmental disorders, such as autism and schizophrenia, are linked to irregular oscillatory patterns in the brain. Individuals with these disorders often perceive the world as disjointed, implying a functional disconnection between various brain regions. This issue will be tackled using a two-pronged experimental approach: i) recording electroencephalograms in children diagnosed with autism, and ii) conducting intracerebral recordings in non-human primates engaged in a behavioral task. To enhance our understanding of the electroencephalographic patterns observed in children diagnosed with autism, we will apply models developed in animals. The primary goal is to comprehend the neurophysiological mechanisms involved in brain processing.
