چکیده
Wed 28/09/2016 1-2pm LC UG06 Prof. Russell Foster, University of Oxford THE BODY CLOCK AND SLEEP: Science to Medicine All life on earth has evolved under a rhythmically changing cycle of light and darkness, and organisms from single-celled bacteria up to man possess an internal representation of time. These 24 hour cycles, termed circadian rhythms, persist in the absence of external cues, and provide a means of anticipating changes in the environment rather than passively responding to them. In mammals, including man, light provides the critical input to the circadian system, synchronising the sleep/wake cycle to the external world. Russell’s talk will include how sleep and circadian rhythms are generated, why sleep is important for health and cognition, how these systems are regulated by light, and the impact of sleep and circadian rhythm disruption on productivity and health.

We believe that the correspondence seminar is a great way to introduce talented high school students to linguistics.
