Photomicrographs showing immunoreactivity for Kv3.1b and Kv3.2 in the SCN during the day and night. 3V, third ventricle; OC, optic chiasm. Top panels: The Kv3.1b immunoreactivity was robust throughout the SCN including the ventral lateral portions as well as a dorsal region of SCN near the 3rd ventricle. Positive staining was seen throughout the rostral to caudal extent of the SCN. The number of immuno-positive cells as well as the density of the staining were significantly higher in the day than in the night. Bottom panels: Kv3.2 immunoreactivity was also seen on cell bodies throughout the SCN. The staining was most robust in the rostral and central aspects of the SCN. Tissue collected from adult C57 BL/6 mice that were perfused during the day or night. Scale bar = 50 μm.
