Stop-signal response inhibition in schizophrenia: Behavioural, event-related potential and functional neuroimaging data

► Stopsignal inhibition was examined in schizophrenia patients (SP) and controls (CS). ► SP were slower to inhibit responses than CS. ► N1 and P3 ERPs to an auditory stopsignal were smaller and later in SP than CS. ► Right inferior frontal gyrus (IFG) activation was reduced in SP. ► Right IFG predicted inhibition speed.
