Document Summary
Cerebellum & basal ganglia in implicit memory, don"t require conscious awareness of learned (e. g. habits, classically conditioned (taste aversion, if nauseous after eat something, next time scent will make nauseous)) Episodic memory: tell chronological story about life; humans & some birds are only animals w/episodic memory. Hippocampus & surrounding cortex (temporal lobe) for explicit memory. H. m. had epilepsy, bilateral damage to hippocampus 20 seizures a day. Knew that seizures from temporal lobes, removed both sides of temporal lobe, including hippocampus. Seizures mostly gone after surgery, but could never learn anything new; old memories were intact - facts already known not stored in hippocampus. Working memory was normal, but couldn"t transfer into long-term memory store. Could learn skills (e. g. draw star on mirror), got better, but never remembered that did task. Priming: read word, and then show first 2 letters; say correct word evoked, but no memory of doing this.
