2-Minute Neuroscience: Suprachiasmatic Nucleus

[1:58]

The suprachiasmatic nuclei (SCN) are thought to be involved with maintaining circadian rhythms, or biological patterns that follow a 24-hour cycle. To accomplish this, the cells of the SCN contain biological clocks. In this video, I discuss the molecular mechanism driving the biological clocks in the cells of the mammalian SCN, and how a cycle of gene expression allows the activity of these cells to follow a 24-hour pattern.
