Figure 4.

External input (left) and activation of the channels recorded in the two cortical layers of a test striatocortical loop. The seven different conditions (one per row, center, and right columns) are determined by the outflow of DA: center column represents activation of the three channels (three colored lines) in the inner layer of the cortex; right column represents the external layer as a B/W colormap (the channels are labeled with the same color scheme seen in the input and inner layer).
