Slow interaural-phase modulation evokes transient P1-N1-P2 waves while faster rates produce steadier following responses

Evidence

Evoked responses to the intermediate IPM rate (6.8 Hz; Fig. 2 ) became steady state at the same rate as the IPM, and so we term this response the IPM-FR. … Responses obtained at 6.8 Hz IPM rate were maximal for IPDs spanning ±45–±90°, whereas responses obtained at 13.4 Hz IPM rate increased monotonically with increasing IPD. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2949 (#qualifies, via linked claim)
