Document Summary
Voluntary movement of mm of body and head. Loss of voluntary control of horizontal eye movement. Broca"s motor speech area motor aspects of speech. Cognition of the body and objects surrounding it. Impairment of sound localization in space, stimulation produces tinnitus. Loss of facial recognition (prosopagnosia) partial/total loss of vision of contralateral visual fields for both eyes depending on extent of lesion in visual cortex. Brodman"s = another guy who connected the anatomical and functional areas of the brain - don"t need to know this. Not everything in cerebral cortex is bilaterally symmetrical. Different composition of neuronal networks allows for specialized function that is different in each hemisphere. Speaking and writing are neuronally intensive - if you put all organizational effort on one side, it greatly reduces the overall energy expenditure. Dominant side can focus on fine detail and extreme control. Non dominant side can focus on broader contextual movements. Ascending = sensory from periphery to the brain.
