Figure 5
c-Fos distribution in primary and secondary motor cortex.
(a,d) Photomicrographs of c-Fos staining in M1 and M2, which control forelimb movements. Scale bars = 200 μm. (b,c) After FSN and PSN rats were startled awake, c-Fos counts significantly decreased in layers II–III of M1 compared with rats that awoke normally. (e,f) c-Fos protein expression was not different among groups in M2. The data are expressed as mean ± SEM. *p < 0.05, **p < 0.01, different from control; #p < 0.05, ##p < 0.01, different from FSC/PSC (Student-Newman-Keuls test). n = 6–8 per group. M1, primary motor cortex; M2, secondary motor cortex.
