The neural basis of deficient response inhibition in children with neurofibromatosis type 1: Evidence from a functional MRI study

Abstract

Impaired response inhibition is a predominant feature of several neuropsychiatric disorders; in general the underlying aetiology of these disorders and associated impairments is unknown. The common occurrence of impaired response inhibition in a single gene disorder such as neurofibromatosis type 1 (NF1), provides a valuable opportunity to explore its mechanistic basis through the study of gene–brain–behaviour interactions. We used functional brain imaging with a Go/No–Go task to examine the neural substrates of response inhibition in children with NF1 and age and gender matched typically developing subjects. Children with NF1 were found to have abnormal activation patterns in several cortic..
