Document Summary
Visual cortex is broken into 3 types. Primary visual cortex area of the cortex that receives most of its input from the visual relay nuclei of the thalamus. Located in the posterior region of the occipital lobes. Secondary visual cortex receive most of their input from the primary visual. Prestriate cortex band of tissue in the occipital lobe that surrounds the cortex primary visual cortex. Inferotemporal cortex cortex of the inferior temporal lobe. Visual association cortex receive input from areas of secondary visual cortex as well as from other sensory areas. Scotoma an area of blindness, in the corresponding area of the contralateral visual field of both eyes. Patients are sometimes unaware of their scotomas due to completion. Hemianopsic scotoma that covers half the visual field. Conscious awareness if someone sees something that they are consciously aware that it is there even though they have no conscious awareness of the stimuli.
