Responses of an IC neuron with simple peak-type behavior. A, Phase plot constructed from BP indicates a CD of +853 μsec and a CP of −0.02. B, ITD functions constructed from the response to binaural beats (see Materials and Methods). C, PSTH showing the response to binaural beats at 225 Hz presented alone or simultaneously with a 125 Hz suppressor tone. D–F, IPD histograms showing the response to binaural beats at 225 (D), 200 (E), and 250 (F) Hz, presented either alone (open bars) or in the presence of the 125 Hz suppressor (lines). G, Phase plot showing the new mean BP values as open circles and the old values asopen squares.
