Annotation

Chronobiology studies temporal rhythmic regulation of biological processes in living organisms, from gene expression to behavior. The biological rhythms may run with a various periods but the most important are circadian, i.e. about one day, rhythms which persist even in a non-periodic environment.

Circadian rhythms can be found in most of the organisms known so far, from unicellular prokaryotic to mammals, including humans. Malfunction of the coordination in the timekeeping system impacts negatively adaptation to external environment, regulation of physiological functions and health.

The lectures may be of interest mostly for bachelor, magister and doctoral students interested in physiology, zoology, molecular biology and biomedicine.
