Unprecedented Data On Circadian Rhythms Revealed

Fluctuations in light intensity allow restoring the regularity of circadian rhythms. In higher organisms, such as mammals, biological or circadian rhythms are generated by a multicellular genetic clock which is located in two regions of the hypothalamus that are connected to each other known as suprachiasmatic nuclei (SCN), containing about 10,000 neurons each. In order to generate and regulate circadian rhythms, our biological clock needs to use the “cooperative cell behavior” of SCN neurons.
