Document Summary
Neuroscience 101: lecture 2 notes (january 19, 2016) Somatic: cat study, manipulate brain and see resultant behavior of patient. L visual field r hemisphere controls l body motor skills. L hand would move b/c r hemisphere controls motor movement of. R hemisphere only knows about l visual field, l hemisphere only knows about r visual opposite side of body field. Preservation of functions (damage to one hemisphere does not disturb all functions) Specialization (improves function by increasing specificity: as human brains became more and more specialized (required to do more functions), brains developed specialized areas for spatial sense. Information flow in brain takes time, so functions that work together commonly should be nearer to each other: ex: all language sites very close together in the left hemisphere temporal lobe (mostly) Lateralization decreases with age, losing speed and ability to use other space in alternative hemisphere to compensate (changing, adapting)
