Document Summary

Not sensory deficit, nothing wrong with visual system; deficit in ability to interpret left side of world. No sensory neglect if left side damaged; right hemisphere mainly for spatial relationships, left side for language. Damage to right parietal: also apraxias, problems with sensory motor integration e. g. lose ability to use fork, or tie shoes; nothing wrong with movement systems or sensory systems; problem w/integration. See function carried out by multiple brain areas: get idea of how the areas interact w/each other develop model e. g. working memory: for image dorsolateral prefrontal cortex & visual cortex. When one brain region activated by many regions that don"t seem to be related see that are related, develop model e. g. anterior cingulate cortex. Half cortex is visual system, use as example of how sensory system organized. Insula: pull back temporal; sensory component of limbic system. Pain & temp into dorsal horn of spinal cord axons in anterolateral pathway spinothalamic tract primary somatosensory cortex.
