Azimuth tuning of nearby neurons in OT. A, Spatial receptive field (SpRF) (top) and azimuth tuning curve (bottom) obtained by averaging the SpRF across elevation. B, Peristimulus time histogram (PSTH; top) and raster (bottom) for the spiking activity of the neuron in A responding to sound at the preferred direction (90° azimuth and 0° elevation). C, Example azimuth tuning curves of neurons recorded from the same site. Responses are normalized to facilitate visual comparison. Tuning curves represent mean ± SEM, 20–40 repetitions.
