Evoked potential correlates of recognition memory.
During word recognition tasks, differences in the stimulus related potentials to 'old' (previously presented) and 'new' (not previously presented) words occurred as early as 160-190 ms after stimulus onset (N1) as well as in the late component of the wave forms (P3). The N1 differences may possibly reflect  underlying neural activity directly related to the recognition memory process.
