Event Related Potentials and Time Estimation

Abstract

ABSTRACT Event related potentials (ERPs) recorded from the scalp of man were studied during a time estimation task. The principal ERP correlate of mental activity associated with time estimation appeared to be a CNV wave followed by a late positive shift. Latency of CNV termination was correlated with temporal judgments. There was some evidence that the onset of CNV termination occurred prior to the estimated time of occurrence of cortical motor command signals associated with production of the temporal judgments.
