That second wave of energy is a normal part of the human circadian rhythm, but lifestyle factors also play a role.

Circadian rhythms are governed by a master clock, a group of neurons called the suprachiasmatic nucleus, located in a region of the brain called the hypothalamus. This master clock translates cues ...

The researchers identified subtle differences in brain wave patterns that predicted which ... Ph.D., physiologist in the ...

Circadian rhythms are the regular ... Bzdok and colleagues delineate the deep phenotyping and brain basis of early risers and night owls at a population scale, showing links to habit formation ...

The molecular mechanism behind why heart attacks can vary in severity depending on the time of day has been uncovered, potentially paving the way for innovative treatments that align with the natural ...

Early experiments showed mimosa leaves still opened and closed in the dark, following their own circadian rhythms rather than the Sun. It sits in the hypothalamus in your brain and, like a ...

The authors “give mechanistic insight for how time-of-day difference in blood-brain barrier permeability comes to be,” says Robert Dallmann, a circadian biologist and pharmacologist at University of ...
