Document Summary
Opc proliferation increases w daylight increases w pregnancy hormones increases w neuronal electrical activity decreases w aging and rem sleep. Blinding animals shortly after birth the areas of brain destined for vision, get taken over by other senses report better audition sensation, sometimes better taste. Sound activates visual cortex of early blinded ppl blind ppl have to locate things from sound, use the same pathways as vision. Ppl born w/o eyes, visual dreams? no real visual dreams in the same sense as us dreams w shots of lights, colours sometimes some things pre-wired in the brain that create these impression but cannot see things. Associative learning - linkage of 2 or more unrelated stimuli to elicit a behavioural response learned associations are a type of explicit memory. Long term potentiation long lasting increase in synaptic effectiveness after high frequency stimulation amplitude of the epsp produced by test pulse increases, ltp has taken place.
