2-Minute Neuroscience: Suprachiasmatic Nucleus


Summary

The video delves into the essential role of the suprachiasmatic nuclei (SCN) in regulating circadian rhythms. It explains how the molecular mechanism within SCN, involving Clock, BMAL1, Per, and Cry proteins, orchestrates the biological clock. The cycle of gene expression in SCN serves as the molecular clock, enabling the body to maintain a synchronized circadian rhythm. Overall, the video provides a detailed insight into the intricate workings of the SCN in controlling our internal body clock.
