CSB346H1 Lecture Notes - Lecture 9: Genioglossus, Non-Rapid Eye Movement Sleep, Slow-Wave Sleep
Document Summary
Csb346 lecture 9 summary respiratory control during sleep. Nrem sleep (deep sleep, slow wave sleep) Stage 2 = sleep spindles and k-complex waves. Stage 4 = delta waves = hard to awaken. Brain waves are similar to awake state. Penile erections (males) and vaginal moistening (females) Vivid dreaming: breathing pattern in sleep. Breathing pattern is regular and metabolically regulated. Breathing pattern is slow and deep: very constant. Breathing pattern is fractionated and variable, and may be dissociated from metabolism: very chaotic, affects the basic physiology of how much o2 and co2 is in the blood. Altered respiratory network activity (activity of respiratory neurons in the vrg: since breathing changes during sleep, the respiratory neurons that generate breathing must be sensitive to changes in sleep, nrem. The respiratory neurons are active when awake, but inactive when asleep: rem. The activity of an inspiratory neuron is sporadic.
