Abrupt sound changes elicit auditory P1-N1-P2 waves at 50, 100 and 175 ms

Evidence

Direct measures of ITD sensitivity, attributed to multiple generator sites in the thalamus and auditory cortex (Picton et al. 1974 ; Hari et al. 1980 ; Näätänen and Picton 1987 ; Liégeois-Chauvel et al. 1994 ), have been demonstrated in auditory-evoked ‘P1-N1-P2’ responses, with abrupt changes in either the ITD (e.g. McEvoy 1991 ), or the interaural correlation of a noise (e.g. Chait et al. 2005 ), eliciting responses with typical latencies of 50, 100, and 175 ms, respectively. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2950
