Fig. 1 Grand averaged waveforms of ERPs time-locked to error response and to correct response obtained from 15 Controls and 12 DAT patients. In the DAT patients, the Ne, Pe and Pc components showed reduced amplitude and prolonged latency. The Nc amplitude in the DAT patients did not differ from that in the Controls (arrows indicate response; DAT: dementia of the Alzheimer type, Controls: control subjects, Ne: error negativity, Pe: error positivity, Nc: correct negativity, Pc: correct positivity).
