Document Summary
However, there are also things we would want to forget. Ptsd: recurring and disturbing memories of certain events (lashbacks) Deiniions: learning: deals with how experience changes the brain; it involves neuroplasicity (the brain"s ability to modify synapic connecions as a result of experience, memory: refers to how these changes are stored and later retrieved. Is memory stored in speciic brain structures: karl lashley"s search for the engram the brain of what has been learned or memory trace- a physical trace or representaion in. He trained rats running through mazes of various levels of diiculty. He disrupted the connecions between brain areas or removed parts of the cortex. He found that no single cut or combinaion of cuts interfered with a rat"s learning and memory of a maze. Richard thompson and colleagues studied simple classical condiioning. The cerebellum stores memory for eye-blink condiioning: why lashley failed and thompson succeeded in inding an engram.
