While we think of the eye as the origin of visual perception, it plays an equally important role in regulating many other body systems. Indeed, information about the amount of light reaching the eye is communicated to a number of brain regions involved in the control of sleep, arousal, metabolism and hormone secretion. Most notably, such information controls the timing of our ‘body-clock’, which in turn regulates rhythmic variations in almost all body processes from athletic ability to cognitive performance. My lab aims to understand how visual signals are communicated and processed within the brain to drive these subconscious changes in physiology and behaviour.
