Figure 9. Examples of NAc response related firing patterns tracked across sessions.

Each row A D shows rasters and peri-response histograms for a single neuron across sessions, as well as the mean waveform recorded during each session. Details are the same as Figure 8. A Most Core neurons were inhibited strongly during response early in training and lost that inhibition by late sessions. B However, not all Core neurons were consistently inhibited during the response. C Shell neurons were also inhibited during response and some maintained that inhibition throughout training. D However, not all shell neurons were consistently inhibited during the response.
