Target azimuth tuning functions from 1 IC neuron, with best frequency (BF) = 7.88 kHz. A–D: raster plots of spike times grouped by location of interferer: co-located, +90°, 0°, and −90°, respectively (positive sign indicates contralateral). Each raster band shows the spike times over multiple repetitions at 1 target azimuth, with each band alternately shaded for clarity. Inset in each panel shows the target azimuth tuning function for the associated interferer location. Target azimuth tuning functions for this neuron overlaid across all interferer conditions are shown in Fig. 4E.
