Fig 3. c-Fos positive cell counts in WT and R6/1 mice of learning groups.

Operant conditioning-induced c-Fos expression in the prefrontal cortex, dorsomedial striatum, dorsolateral striatum, septum, CA1 and dentate gyrus of the hippocampus, and lateral nucleus of amygdala. * significant difference (p < .05) between age-matched genotype groups. 2 months: WT, n = 8, R6/1, n = 7; 4 months: WT, n = 8, R6/1, n = 6; 6 months: WT, n = 7, R6/1, n = 8.
