DICHTER, Auteur Article en page(s) : p.2903-2913 Langues : Anglais (eng) Mots-clés : Autism  Functional magnetic resonance imaging  cognitive control  Repetitive behaviors  Frontostriatal Index. décimale : PER Périodiques Résumé : This study investigated cognitive control of social and nonsocial information in autism using functional magnetic resonance imaging. Individuals with autism spectrum disorders (ASDs) and a neurotypical control group completed an oddball target detection task where target stimuli were either faces or nonsocial objects previously shown to be related to circumscribed interests in autism. The ASD group demonstrated relatively increased activation to social targets in right insular cortex and in left superior frontal gyrus and relatively decreased activation to nonsocial targets related to circumscribed interests in multiple frontostriatal brain regions. Findings suggest that frontostriatal recruitment during cognitive control in ASD is contingent on stimulus type, with increased activation for social stimuli and decreased activation for nonsocial stimuli related to circumscribed interests.

Neural Mechanisms of Emotion Regulation in Autism Spectrum Disorder / J. Anthony RICHEY in Journal of Autism and Developmental Disorders, 45-11 (November 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-11 (November 2015) . - p.3409-3423 Titre : Neural Mechanisms of Emotion Regulation in Autism Spectrum Disorder Type de document : texte imprimé Auteurs : J.

DICHTER, Auteur Article en page(s) : p.3409-3423 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Dorsolateral prefrontal cortex  Amygdala  Nucleus accumbens  Emotion regulation  Eyetracking Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is characterized by high rates of comorbid internalizing and externalizing disorders. One mechanistic account of these comorbidities is that ASD is characterized by impaired emotion regulation (ER) that results in deficits modulating emotional responses. We assessed neural activation during cognitive reappraisal of faces in high functioning adults with ASD. Groups did not differ in looking time, pupilometry, or subjective ratings of faces during reappraisal. However, instructions to increase positive and negative emotional responses resulted in less increase in nucleus accumbens and amygdala activations (respectively) in the ASD group, and both regulation instructions resulted in less change in dorsolateral prefrontal cortex activation in the ASD group. Results suggest a potential mechanistic account of impaired ER in ASD.

Reward Circuitry Function in Autism During Face Anticipation and Outcomes / Gabriel S. DICHTER in Journal of Autism and Developmental Disorders, 42-2 (February 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-2 (February 2012) . - p.147-160 Titre : Reward Circuitry Function in Autism During Face Anticipation and Outcomes Type de document : texte imprimé Auteurs : Gabriel S. DICHTER, Auteur ; J. Anthony RICHEY, Auteur ; Alison RITTENBERG, Auteur ; Antoinette SABATINO-DICRISCIO, Auteur ; James W. BODFISH, Auteur Année de publication : 2012 Article en page(s) : p.147-160 Langues : Anglais (eng) Mots-clés : Autism  Nucleus accumbens  Anticipation  Functional magnetic resonance imaging  Social cognition  Reward Index. décimale : PER Périodiques Résumé : The aim of this study was to investigate reward circuitry responses in autism during reward anticipation and outcomes for monetary and social rewards. During monetary anticipation, participants with autism spectrum disorders (ASDs) showed hypoactivation in right nucleus accumbens and hyperactivation in right hippocampus, whereas during monetary outcomes, participants with ASDs showed hyperactivation in left midfrontal and anterior cingulate gyrus. Groups did not differ in nucleus accumbens responses to faces. The ASD group demonstrated hyperactivation in bilateral amygdala during face anticipation that predicted social symptom severity and in bilateral insular cortex during face outcomes. These results add to the growing body of evidence that autism is characterized by altered functioning of reward circuitry. Additionally, atypical amygdala activation during the processing of social rewards may contribute to the development or expression of autistic features.
