Summary

Description
English: fMRI-derived image of difference between brains of autistic and control groups. Legend reads "Activation during visuomotor coordination: Autism Group [yellow], Control Group [Blue], Overlap (both groups) [green]". for Laurent Mottron*, "Even researchers who study autism can display a negative bias against people with the condition. For instance, researchers performing functional magnetic resonance imaging (fMRI) scans systematically report changes in the activation of some brain regions as deficits in the autistic group — rather than evidence simply of their alternative, yet sometimes successful, brain organization".

Français : Imagerie IRMf montrant les différences d'activité du cortex cérébral lors d'une activité de coordination visualo-motrice chez des personnes autistes et appartenant à des groupes-témoin. Les zones activées apparaissent jaunes pour le groupe des autistes [bleu pour le groupe de contrôle et vert quand elle est la même pour les deux groupes. Pour Laurent Mottron, neuropsychiatre et spécialiste de l'Autisme, les différences d'activation de certaines régions du cerveau montrées par l' imagerie par résonance magnétique fonctionnelle (IRMf) pourraient ne pas être seulement à considérer comme une preuve d'un trouble du fonctionnement du cerveau, mais aussi la preuve d'une organisation alternative du cerveau (observée comme efficace, par exemple lors de tests d' intelligence non-verbale).(Source : Laurent Mottron, Changing perceptions: The power of autism ; Nature 479, 33–35 (03 November 2011) ; doi:10.1038/479033a En ligne : 2011-11-02)
