Document Summary
Posterior- sensory inputs (visual cortex, auditory cortex, somatosensory cortex) Associative process- binds information together from different senses- this is essentially the parietal lobe (key part) For each lobe, you should know its location, functions and key sub-regions. For each sub-region, you should know the location and main functions. Cortex folded= more surface area= more space for neurons. Organization of the cortex: two hemispheres with hemispheric specialization and contralateral organization. The two halves are connected by the corpus callosum. Hemispheric specialization does not mean that only one hemisphere is involved with a certain type of cognitive processing- it means that the majority of a certain type of processing occurs in one hemisphere. Function: communication and integration of info from l and r hemispheres. On the r hemisphere: fusiform face area= facial recognition (damage to this area= prosopagnosia) Wernicke"s area- located near auditory cortex- plays a role in the comp. of speech/auditory info. Sub-regions: primary somatosensory cortex, inferior parietal lobe/geschwind"s area.
