Differences in Auditory Scalp Potentials Evoked by Meaningful Words and Nonlinguistic Stimuli

Abstract

Differences in auditory evoked potentials with meaningful words and their reverse playback may reflect different neural processes in recognizing auditory Stimuli. Auditory evoked potentials with the words and their reverse playback were analyzed for eight volunteers, and a maximal difference was observed at a latency around 400 msec. over the left middle temporal central area.
