Document Summary
Physl 212 - lecture #11 - genes, synapses and the hippocampal memory. Step by step procedure (eg. bike riding) Short and long term memory: short term memory. Continual rehearsal to be effective: long term memory. Once info is in ltm, ain"t needing rehearsal: consolidation: storing new info into ltm. Multiple storage sites for memories: acquisition and storage of declarative information. Ltm: wernicke"s area of speech comprehension; temporal cortex for memories of objects and faces: acquisition and storage of nondeclarative information. Stm: sites unknown but probably spread out. Ltm: cerebellum, basal ganglia, premotor cortex (ie. motor behaviour sites: hippocampus is not final resting place of ltm. Other sites are involved ie. tucked away in cortical sites of the hippocampus: massive amounts of connections and projections in the neocortex projects out of the hippocampus. Amnesia: retrograde: inability to remember anything prior to trauma. Very old memories remain intact: anterograde: inability to form new memories.
