Mean firing at reward (40-240 ms after reward delivery) for neurons projecting to each striatal region. Putative DLS- and VLS-projecting neurons showed significantly higher firing rates than DMS-projecting neurons (p< 0.05 and p< 0.005 respectively) and compared to shuffled baseline periods (p< 0.05 and p< 0.05); Kruskal-Wallis one-way ANOVA on ranks with Tukey’s post-hoc test;**p< 0.01.
