  • Abstract
  • Look Inside

 P300 component was first described by Sutton et al., and was shown to be an endogenous ERP relating to uncertainty about the nature of the forthcoming stimulus. Up to that time, human experiments had not demonstrated a relationship between the meaning or significance of a stimulus and the evoked potential. Since a number of experiments have been done for two decades on the nature of P300 especially by psychologist, it is now the most popular endogenous ERP to test cognitive function of normal human being as well as patient.

 Typical experimental condition for the recording P300 is counting of or attending to infrequent stimuli within a series of frequent ones (oddball paradigm). P300 is recorded if a signal is detected, but not after a missed signal.
