Cerebral Cortex continued 4 Lobes Frontal Higher functions: language, thought, memory, motor functioning Motor cortex (carries out ____________movements) Broca’s area (related to physical production of speech; damage to this area results in difficulty speaking—inability to process language—trouble putting thoughts into words) Parietal Somatosensory cortex (controls experience of bodily sensations; touch, temp, pain) Important for regulating processes of attention and working memory Occipital (contains primary _________ cortex) Temporal (language, memory, hearing, perceiving forms; auditory; Wernick’s—speech production—no trouble producing speech, but what is produced is not very meaningful)
