c-Fos expression in the Suprachiasmatic Nucleus (SCN) of mice fed rodent high fat diet and cheese.

(A) Graph showing mean (±SEM) number of c-Fos-immunoreactive (cfos-IR) nuclei in the SCN of AL controls (black), CH (green), and HF (red) at ZT 5 (TP -3 hours) and ZT 7 (TP -1 hours). TP 0 represents time of PM presentation as highlighted by the vertical dotted line on the x-axis. (B) Representative coronal brain atlas image with Nissl stain showing location of the region examined (adapted from Paxinos and Franklin). (C) Representative micrographs at TP -1 of c-Fos expression in the SCN. MPO, medial preoptic area: V3, third ventricle.
