Fig 4. Receptive field transformations of the high-resolution network indicate that spectro-temporal information propagates with minimal processing across network layers.

(a) Example spectro-temporal receptive field (STRF) measured for the optimal network maintain high-resolution and change minimally across network layers. Unlike the optimal network, the measured (b) integration times and (c) latencies change minimally and are relatively constant across the six network layers. (d) Bandwidths, by comparison, increase slightly across the six network layers. The figure format follows the same convention as in Fig 3.
