PSY 0505 Study Guide - Midterm Guide: Basal Forebrain, Raphe Nuclei, Slow-Wave Sleep
Document Summary
Sync slow wave sleep w k complexes. K complexes are reactions to sensory input. Proportion of delta waves increases to 85% Parts of your cortex are aroused thats why you still have alpha waves making it a pradoxical state of consciouneness. Ventra laterateral preoptic area and arousal systems (raphe nuclei, locus coerulus, dorsal pons, basal forebrain, tuberomalliary nucleus) work to inhibit each other and whichever has more gaba is inhibited for the time being. Changes as they day goes on like a see-saw. Orexin has a excitary effect on arousal systems which keep us awake. When sub lateral dorsal area is firing (activity increased) means. When vpag is active then rem sleep is prevented. Orexin keeps vpag active in wakefulness and slow wave sleep. Needed for the activational effect of male phenotype developmenent. During the puberty testosterone will aid the development of male gonads. If missing then gonads look ambigious upon birth.
