Document Summary
Psych 261 physiological psychology. Module 13. 1: learning, memory, amnesia, and brain functioning. Individual"s response determines the outcome: animals have specialized methods of learning that may not fall under classical or instrumental conditioning. Long- term memory has a higher capacity than short- term memory. Information enters short- term storage where it stays until brain can consolidate it into long- term memory. Plaques form, causing cerebral cortex and hippocampus to deteriorate. Inhibited by curcumin: tau protein is phosphorylated in high levels of amyloid- b. Unable to bind to targets within axons, so it attacks cell body and dendrites. Responsible for tangles formed from neuron degeneration. Other brain areas in memory: associative memory (ability to elaborate on memory spontaneously) impaired with people with parietal lobe damage. Module 13. 2: storing information in the nervous system. Stronger stimulus intensifies later withdrawal response to touch. Excites facilitating interneuron that releases serotonin, blocking potassium channels and continuing neurotransmitter release for longer than usual.
