The SCN

The other day I came across this beautiful staining of the SCN (the suprachiasmic nucleus located within the anterior portion of the hypothalamus). Even if you are not familiar with its critical role of regulating sleep and wake cycles, reproductive behaviors, core body temperature, hormone and neuropeptide secretion, or any other circadian rhythm, at least appreciate the aesthetics of immunostaining.
