PSYC 207 Study Guide - Final Guide: Morris Water Navigation Task, Spatial Memory, Working Memory
Document Summary
Psyc 207 exam 2 review (december 14, 2010) Rats with hpc lesions in some cases, just can"t figure it out. Constant (start at same place everytime)/variable start (start at diff place everytime) rats with hpc lesions/normal rats (fake lesions) On slide, see graph d) hpc lesions larger error on graph. *hpc must be used for spatial enconding/manipulation of environment/spatial memory. *idea of place cells happened after this so water maze enforced research on place cells. Hpc lesions have deficit to variable start= could not manipulate spatial cues at the time, indicated that hpc used for spatial memory. Should learn that if tone and light together don"t press bar. Working memory= keeping something in mind and rehearsing need pfc. Pfc 2 bowls in front monkey, one bowl with treat, monkey can see treats, cover bowls with cards, wait, monkey has to pick one with treat inside monkey with no pfc can"t keep in mind which bowl has treat.
