Build-up of Action Representation in Autism Spectrum Disorders (ASD-BARN)

25. august 2022 oppdatert av: Hospices Civils de Lyon

Build-up of Action Representation During Neurodevelopment: Dysfunctions in Autism Spectrum Disorders?

Autistic spectrum disorders (ASD) are highly debilitating developmental syndromes which core feature is social and communications disorders. Motor skill impairments are frequently described in autism, but few studies have addressed the question of their origin and their specificity. Furthermore, it is not clear whether motor problems encountered in autism are related to dyspraxia, or if they present with specific features. This project aims at deciphering the origin of motor problems encountered by children who grow-up with autism in order to propose early interventions that could influence the other developmental trajectories, such as the social one.

Brain dynamics during sensori-motor learning is explored by applying magnetoencephalography (MEG) during the Bimanual Load-Lifting paradigm. Different motor processes namely: proprioceptive monitoring, use and update of a sensori-motor representation, anticipatory executive control will be correlated to brain oscillation modulation, both topographically and temporally. Two groups of children (aged between 7 and 12) are compared: a group of children with ASD and a control group of typically developing children.

Tiltaksbeskrivelse
Tidsramme
Changes of cerebral oscillations in three frequency bands (alpha, beta, gamma) during sensori-motor learning.
Tidsramme: Day 1
Oscillatory measures are computed in the sensor and source space in order to identify the regions involved in the sensori-motor learning in the control group and in the ASD group.
