Chronobiology of Cognition

Meaning

Chronobiology of cognition is the study of how the brain’s cognitive functions, such as memory, attention, and executive function, fluctuate in predictable patterns dictated by the body’s intrinsic biological rhythms, particularly the circadian rhythm. This field examines the time-of-day dependence of mental performance and its profound link to the rhythmic secretion of key hormones and neurotransmitters. Clinical application involves aligning cognitive demands with an individual’s optimal biological time for peak mental efficiency. Recognizing and respecting these rhythms is essential for neuroendocrine health.
