Figure 2. Spectrogram and waveform of the ten call exemplars used in this study and the resulting responses. A.

. The waveforms of the vocalizations and the responses to them of example neurons shown as PSTHs. The examples shown here all respond to all elements of the waveforms and hence produce a good representation (isomorphic) of the original waveform envelope. B. Spectrograms and PSTHs of the responses to the 10 vocalizations. Here all examples show neurons that only respond at the onset of the vocalization.
