Document Summary
Memory: process that encodes, stores, and retrieves learned experiences: can be transient vs durable (short tem vs. long term), explicit vs. implicit, permit time travel, certain forms of memory are more vulnerable to disease/disruption than others. Habituation: waning of sensitivity by repeated stimulation o. Aplasia = sea slug that"s a model used to study habituation touching its siphon causes gills to withdraw, but if touch repeatedly, the reflex reduces in magnitude and eventually stimulus gives no response. Learning: process by which experiences change our ns physically; involves learning relationships b/w stimuli in environment, recognizing categorization + objects of situations, info about events, skilled actions. Synaptic plasticity: hp: consists of hippocampus, dentate gyrus, subicular complex, ammon"s horn (ca1-ca4) o. Ltp can be measured through electrodes in dentate gyrus that wch measures population epsp (epsps created by many synapses in the dentate) Stimulating performant path with fast excitatory bursts pop epsp in dentate will increase in size.
