Document Summary
Lecture 5 sleep and health & the brain in sleep (february 5, 2016) The bigger it is, the more effects there will be. Body is more tired because it is fighting off bacteria. Spectral analysis is when you compare different waves while you are sleeping. Rem decreases because internal thermostats turn off during rem. With infection when you are running a fever, you get less rem because you will get really cold (same with small animals) Still 90 min cycles, same time of fatigue. Cytokine response is a way the body identifies and fights infections signals wbcs to fight germs: also trigger sleep changes. Immune response signals brain to increase n3 and decrease rem. Species pov because it helps prevent contagion among species (stay home and relax as opposed to going out and infecting other animals) Vaccine is less effective if a messed up sleep pattern: immune system is highly tied to n3 sleep especially.
