Topic: acute circadian disturbance

The endogenous circadian rhythm of organisms maintains fundamental physiological processes and behaviour by synchronising them to the external environment. Disturbance to this rhythm in our modern societies, caused by the use of artificial light in dark periods, electronic gadgets, shift work, and poor sleep hygiene negatively impacts physiological and cognitive health. Studies in rodent hippocampus show that neuronal membrane excitability shows a diurnal rhythm and disturbance to the circadian cycle impairs hippocampal plasticity and memory. However, it is not clear how acute circadian distur
