Fig. 9.

Similar format to those in Figures 7 and 8 showing responses of an IC neuron with an intermediate-type phase plot with a CD of +102 μsec and a CP of +0.20 (A).B, ITD functions of all frequencies. PSTH (C) and IPD histogram (D) of the response to binaural beats at 250 Hz either presented alone (open bars) or in conjunction with a 100 Hz suppressor (lines). E–H, IPD histograms of the response to binaural beats either presented alone (open bars) or in conjunction with the suppressor (lines) for stimulus frequencies of 150 (E), 350 (F), 450 (G), and 550 (H) Hz.I, Phase plot showing BPs from the original phase plot in A for frequencies not reexamined (filled circles), frequencies that were reexamined (open squares), and those BPs obtained in the presence of the suppressor (open circles).J, ITD functions of the revealed peak-type input.
