Welcome to the seventh episode of The Brain Podcast - the official podcast of the journals Brain and Brain Communications. In this episode we chat with Dr Nina M Rzechorzek, lead author of the article entitled: A daily temperature rhythm in the human brain predicts survival after brain injury We discuss how brain temperature was measured using invasive and non-invasive methods to identify a physiological daily rhythmicity. The loss of this brain rhythm was strongly predictive of survival in patients with traumatic brain injury. Our longest episode to date but packed with fascinating science!
