Document Summary

Receives input from: somatosensory cortex, visual cortex, auditory cortex, hippocampus. Visuomotor integration (controlled hand movement guided by vision) Selective attention (distinguishes and responds to selective stimuli in a busy environment) Spatial perception (evaluates arrangement in space & investigates relationships) Left ppc: dominant hemisphere in language and carrying out motor tasks: aphasia: disorder of language, apraxia: impaired performance of learned motor responses even though, there are no motoric problems, no sensory loss, no loss of motivation. Ideo-motor apraxia: inability to carry out simple motor activity in response toverbal command (worse when asked to imitate or pantomime) Eliminating the communication between the hemispheres, by sectioning of the corpus callosum. Corpus callosum facilitates communication between the 2 hemispheres. Can induce split brain with sodium amytal, which puts half of the brain to sleep. The infinite number of ways to execute a movement/action sequence. Solution: attempt to reduce the functional degrees of freedom as part of the control strategy.
