(A) Diagram of auditory input to the songbird brain. Nuclei OV projects to the primary auditory region Field L, which has bidirectionally projections with NCM and CMM. NCL (not pictured), lateral to NCM, additionally exhibits bilateral projections with Field L. (B) A visualization of recording sites, shown over top of the starling brain atlas65. Colors are consistent with panel A, with NCL being shown in purple. (C) The top of each panel shows a spectrogram of the morph stimulus played back. Below, a trace is shown for three cue conditions (No cue, P(Rl∣C) = 0.125, and P(Rl∣C) = 0.875) corresponding to the average Gaussian convolved spike vector and 95% CI for active trials. Below the trace are sample spike rasters for each cue condition, where each row is a trial. Below the rasters, the sample trace and raster plots are repeated for the same unit in the passive trial condition.
