PSY 4327 Lecture Notes - Lecture 4: Sleep Onset Latency, White Noise, Cytokine
Document Summary
More stage n3 and more intense: spectral analysis how you compare different waves. Very cold/hot/fever less rem: thermostat turns off during rem, cytokines messengers that signal wbc to show up and trigger more cytokines, also trigger sleep changes, to increase n3 and decrease rem. Adaptive for species contains not spreading infections through population. Sleep dep lowers immune response, makes vaccines work less efficiently. Nature of aids no immune system to prompt extra n3 despite needing it, cytokines missing suspected mechanism. Sleep continuity cortisol linked to acetylcholine, keeps more awake, less deep sleep, Possibly adaptive need to be awake for invasions, etc. Animal studies stress physical stress, not emotional/psychological: extra recovery even if no sleep is missed.
