Neurons responsive to the tutor song in 45 dph LMANshell and LMANcore. A, Recording from LMANshell. Top, Song spectrograms of a 45 dph bird's TUT, BOS, and REV. Below are raster plots and instantaneous firing rates for a TUT-excited single unit; overlaid waveforms are shown in inset (see Materials and Methods and Fig. 2B,C for recording and spike sorting details). Scale bar, 0.5 ms. * indicates response significantly different from baseline activity. B, Recording from LMANcore of 43 dph bird, arranged as in A showing responses to TUT, BOS, and REV. C, Recording from LMANshell of 45 dph bird showing a TUT-suppressed single unit, arranged as in A and B showing responses to TUT, BOS, and AMC.
