c-Fos mRNA expression after a DMS test with fixed 0- or 24-sec delays. (A–C, left) Rat brain coronal outlines according to (Paxinos and Watson 2005), with the brain areas used for the c-Fos mRNA analysis as highlighted. (A–C, middle and right) Quantitative analysis of c-Fos mRNA puncta within the outlined regions of interest corresponding to the prelimbic cortex (PrL), orbitofrontal cortex (OFC), primary motor cortex (M1), dorsolateral striatum (DlS), dorsomedial striatum (DmS), nucleus accumbens (NAc), CA1 and CA3 subregions of the hippocampus, perirhinal cortex (PrH), nucleus reuniens (NRe), and central amygdala (CeA) in rats that underwent a single DMS test with fixed 0- or 24-sec delays, and in home-cage controls (Ctrl). Mean ± SEM, (*) P < 0.05 versus Ctrl group, (#) P < 0.05 versus 0-sec delay group. n = 5–8/group.
