Caudate and cerebellar involvement in altered P2 and P3 components of GO/NoGO evoked potentials in children with attention‐deficit/hyperactivity disorder

Previous studies showed reduced activity of the anterior cingulate cortex (ACC) and supplementary motor area during inhibition in children with attention-deficit/hyperactivity disorder (ADHD). This study aimed to investigate deep brain generators underlying alterations evoked potential components triggered by visual GO/NoGO tasks ADHD compared typically developing (TDC). Standardized weighted low-resolution electromagnetic tomography (swLORETA) source analysis that lower GO-P3 component was explained not only a contribution frontal areas but also stronger part caudate nucleus these TDC. While reduction NoGO-P3 essentially dorsal ACC, higher NoGO-P2 amplitude concomitant dorsolateral prefrontal cortex, insula, cerebellum. These data corroborate previous findings fMRI offered insight relative precise time-related cerebellum automatic feature processes ADHD. results were discussed regarding involvement fronto-basal ganglia fronto-cerebellum networks attention
