another name for the primary visual cortex is the
56. where do the sensory areas of the cortex occur. parietal, insular, temporal and occipital lobes. 57. function of primary somatosensory cortex. receive information form the general (somatic) sensory receptors in the skin and from proprioceptors (position sense receptors) in the skeletal muscles, joints and tendons. Called also first visual area. visual cortex the area of the occipital lobe of the cerebral cortex concerned with vision; the striate cortex is also called the first visual area, and the adjacent second and third visual areas serve as its association areas. Structure. This is the term for the primary visual cortex, V1, or Brodmann’s area 17. The area encompasses the medial surface and a small lateral surface of the occipital lobe, and is within the calcarine sulcus. It is located at the most posterior portion of the cerebral hemisphere. Noun. 1. visual cortex-the cortical area that receives information from the lateral geniculate body of the thalamus. visual area. cortical area, cortical region-any of various regions of the cerebral cortex. includes the eye, the optic nerve and the optic cortex in the cerebrum. The oculomotor, trochlear, abducent, trigeminal and facial nerves are all involved in reflexes which are part of the animal's responses to visual stimuli. 50. each hemisphere is chiefly concerned with the sensory and motor functions of which side of the body. the contralateral side. 51. what are the motor areas. primary motor cortex, premotor cortex, ,broca's area, and the frontal eye field. 52. function of premotor cortex. helps the plan movements. 53. n. The region of the cerebral cortex occupying the entire surface of the occipital lobe and receiving the visual data from the lateral geniculate body of the thalamus. Also called visual area. The calcarine cortex is perfused by the calcarine artery, which is a limb off the posterior cerebral artery. Our visual system has evolved such that damage to one eye does not result in blindness in one visual field. Damage to either the right or left calcarine cortex results in a contralateral field cut, a hemianopia. 41. what is responsible for the communication between the cerebral areas and between the cerebral cortex and lower cns centers. cerebral white matter. 42. what are the fiber types in cerebral white matter. association, commissural and projection. 43. Area 17 (which is also called the striate cortex or area because the line of Gennari is grossly visible on its surface) is the primary visual cortex, receiving the visual radiation from the lateral geniculate body of the thalamus.
