Figure 3.

Membrane potentials, ν_M, as a function of time in the model MSO neuron with rapidly decaying inhibition for a stimulus tone at 1000 Hz: ν_M in the contralateral dendrite (light blue dashed line), ipsilateral dendrite (black dash-dotted line), contralateral (red line) and ipsilateral (black dotted line) halves of the soma (curves overlap), and the axon (dark blue line). (A), (C), (E) ITD = 200 μs (best-ITD, bilateral inputs in-phase). (B), (D) ITD = −300 μs (bilateral inputs out-of-phase). Axonal action potentials occur frequently for (C), (E) coincident binaural EPSPs, and rarely for (D) a large monaural EPSP.
