Figure 8.

The D1 antagonist SCH-23390 infused into the NAc does not significantly alter VP neuronal responses to DS onset, except when infused bilaterally. A–E, Heat maps depicting firing responses of neurons that were significantly activated by DS onset. Data from the same neurons (in the same order) are shown before (pre, upper) and after (post, lower) infusion. F–J, Correlation of mean Z-score of response in the 40- to 180-ms window following DS-onset before and after infusion. K–O, Same as F–J but for the response window of 180–400 ms following cue-onset.
