Brain
. 2014 Jul;
137(Pt 9):2600-10.
PMID: 25070512
It has been suggested that the restricted, stereotyped and repetitive behaviours typically found in autism are underpinned by deficits of inhibitory control. The biological basis of this is unknown but...

210(4):499-510.
PMID: 20424829
Introduction: Acute tryptophan depletion (ATD) temporarily lowers brain serotonin (5-HT) synthesis, and behavioral studies have shown that this alters the processing of facial expressions of emotion. Materials And Methods: The...

A functional magnetic resonance imaging study of inhibitory control in obsessive-compulsive disorder
Page L, Rubia K, Deeley Q, Daly E, Toal F, Mataix-Cols D, et al.
Psychiatry Res
. 2009 Nov;
174(3):202-9.
PMID: 19906516
People with obsessive-compulsive disorder (OCD) have abnormalities in cognitive and motor inhibition, and it has been proposed that these are related to dysfunction of fronto-striatal circuits. However, nobody has investigated...
