ITD sensitivity of a neuron that receives only contralateral excitation but binaural inhibition in response to 100 msec SAM stimuli. A, Normalized discharge rates to SAM stimuli with 100, 200, and 400 Hz modulation rates. Note that the peaks shift as a function of the modulation frequency, whereas the troughs are rather stable. B, Histograms showing the monaural responses to 100 Hz SAM as a function of the modulation phase (left panels). The regression line of the interaural phase delays measured for different SAM rates indicate an EI coincidence mechanism (right panel). For details, see text.
