Systematic conduction delay changes along the nucleus laminaris axis encode interaural time difference maps

Evidence

Neurophonic responses to ipsiand contralateral clicks at best ITDs at or near 0 μs generated similar ipsiand contralateral click responses, which largely overlapped (Fig. 1b ). Responses to both ipsilateral and contralateral stimulation showed a steady increase in latency along the iso-frequency axis in NL (Fig. 1c ), i.e., systematic changes in conduction delay underlay the formation of the maps of ITD. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2856
