Unformatted text preview: There is also motor cortex, which controls voluntary movements, and pre-motor cortex which is involved in initiating movements. Specializations of Human Cerebral Cortex cerebral cortex lower vertebrates are lacking ____________ cerebral cortex is the largest part of the human brain. In sensory systems we have covered primary somatosensory, auditory and visual cortex Higher sensory areas such as extrastriate visual areas in the what pathway and the where pathway. Even including all of the higher sensory areas, there are still large areas of cortex which we have not yet talked about. These areas are called association cortex. Association cortex is almost non-existent in lower mammals like rodents. Visual ortex m o t o r s o m a t o Frontal Association Temporal Lobe ccipital Parietal Frontal Lobe Parietal Association & motion Language/ spatial o r a l a s s o c i a t i o n e x t r a s t r i a t e v i s u a l T e m p o r a l a s s o c i a t i o n 3 subdivisions of human association cortex. 1) Prefrontal cortex: involved in ______ complex motor actions 2) Limbic cortex: involved in _____________________ 3) Parietal-temporal-occipital cortex: involved in ___________ of sensory functions and _____________. All three association areas are interconnected. planning memory and emotions integration language Since these association areas are unique to humans they have been quite difficult to study. Most of what we know about association cortex comes from studying patients with brain lesions. Brain lesions can be caused by trauma, cardiovascular disease, tumors, psychiatric disorders or by brain surgery to correct behavioral or neurological disorders. Patients with lesions in the three different association areas have very different symptoms. Patients with lesions in the 3 different association areas have very different symptoms. Association areas are relatively unique to humans Therefore difficult to study neurophysiology Study through brain lesions caused by trauma, cardiovascular disease, tumors, psychiatric disorders or by brain surgery to correct behavioral or neurological disorders prefrontal cortex lesions: cognitive planning Phineus Gage Frontal Lesions Alzheimers disease _________ deficits difficulty _________ movements prefrontal cortex: reduced activity during sleep or coma prefrontal cortex: abnormal in schizophrenia Frontal and Prefrontal Cortex Patients with lesions in the temporal lobe part of the limbic cortex...
