Two brain nuclei controlling circadian rhythms are identified by GFAP immunoreactivity in hamsters and rats.

abstract：:In the rat the response of suprachiasmatic nucleus neurons to steady retinal illumination at different adaptation luminances was studied. The results confirm that in this nucleus the discharge rate is more commonly increased than suppressed by light. Interval histograms indicate that a complex process underlies the di...
