Document Summary

> object geometry: ability to reconstruct previously viewed items. task relies on short-term visuospatial memory (visuospatial working memory: studies on fmri on human patients w lesions to dorsolateral prefrontal cortex: confirmed role for dorsal premotor cortex in visuospatial working memory. reflects potential planning of motor movements required if imagined task were real. damage= inability to form new memories for places. memories for places formed before damage is unaffected: cells w/in hippocampus respond when rat is moving through space. posterior portion of hippocampal formation significantly larger in taxi drivers than those of control group. volume if hippocampus related to how long participant had been taxi driver: longer the time, larger the hippocampus. Increase reflects brain"s ability to change in response to daily demands that person places on his/her brain: hippocampal formation implicated in related form of spatial learning.
