Sensitivity of MSO neurons to ITDs calculated for the highest modulation rate to which each neuron responded (>0.5 spikes per cycle and stimulus presentation). A, The distance from the peak of the ITD function to the 75% point closest to 0 ITD was taken as an index of ITD sensitivity (indicated by theshaded area). B, Distribution of ITD sensitivity of 37 MSO neurons. Note that maximal ITD sensitivity depends in part on the maximal SAM rate to which a neuron responds (for details, see text).
