Stage 4= slow wave deep sleep (sleep walking) 198. 199. REM 200. 201. Stage 5= Brain is active, internal stimulation from PGO spikes 202. -visual, auditory, motor area active 203. -PFC active 204. -memory consolidation 205. -primed hippocampus 206. 207. Theta waves= 208. - regular repeating waves 209. -produced by areas of the hippocampus and surrounding cortex 210. -6 cycles per minute 211. 212. awake animals= produce theta rhythm during behaviors learned for SURVIVAL 213. asleep animals= produce theta waves during REM sleep 214. cells in hippocampus= fire longer in response to single stimulus in theta waves 215. 216. PGO spikes: pontine- geniculate- occipital 217. -originate in brainstem area (pons) 218. -activate visual cortex & motor cortex 219. -inhibits motor neurons in spinal cord 220. 221. frontal lobes= sense of random “internal” sensations 222. activation- synthesis model of dreaming. 223. 224.
