Summary

An MRI Study in Subjects with Autism Spectrum Disorder and Subjects with Food Addictive Disorder compared to healthy volunteers.

Detailed description

An MRI Study in Subjects with Autism Spectrum Disorder and Subjects with Food Addictive Disorder compared to healthy volunteers, where pathophysiology common to both disorders, based on a dysfunction of the reward system. The project we propose aims to explore the neural networks underlying these alterations in patients suffering from autism or addictive disorder.

Conditions

• Autism Spectrum Disorder

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	MRI	an fMRI measurement of the BOLD physiological signal for sensory responses
DIAGNOSTIC_TEST	EEG	These tests, through videos with a social or non-social content (human presence or absence on the stereoscopic projection), will allow us to study two types of sensorialities (visual and interoceptive). Thus, it will be possible to obtain inter- and exteroceptive profiles of the participants, a direct reflection of the processing of the internal bodily sensations of the body.
