CM  represents  the  task-­‐relevant  components  of  song,    by  encoding  their  acous6cs  and  the  differen6al  behaviors  that  these  acous6cs  signal.

Fig. 4. Context dependence of CLM and CMM responses to repeated motifs. (a)

Response of an example CLM neuron to a single song illustrating context depen-

dence to repeated motifs. Motif types are denoted as letters below the spectrograms.

Motifs of the same type were judged to be acoustically similar for the purposes of the

context dependence analysis (Materials and Methods). (b) Response of an example

CMM neuron to the same song, as in (a). (c) Distribution of mean coefficient of varia-

tion (CV) across repeated motifs for all CLM and CMM neurons. The CV is computed

from the firing rates across each sequence of repeated motifs and averaged for each

neuron. Higher CV values indicate greater context dependence.
