Sleep and Circadian Neuroscience

The goal of this research theme is to understand the links between disruption of circadian rhythm and mental illness.

Endogenous 24-hour (circadian) rhythms are found across almost all forms of life, from plants to humans. These rhythms exist at multiple molecular and cellular levels and allow organisms to optimally align physiology and behaviour to daily cycles of light and dark.

Well-synchronised circadian rhythms are fundamental for human health and are particularly important for cognitive function and mental wellbeing. This is particularly important for young people, who may be more sensitive to light-induced circadian dysfunction and associated mental health problems.

The goal of the Sleep and Circadian Neuroscience research theme is to better understand the mechanistic links between circadian disruption and mental illnesses such as depression and bipolar disorder.

We make use of a wide range of data sources, including:
