PSYA01H3 Lecture Notes - Lecture 9: Visual Cortex, Temporal Lobe, Frontal Lobe
Document Summary
The cerebral cortex is the place where high level perception of the world occurs and is also the place where controlled motor activities originate. In this sense, it is the place where all our controlled interaction with the external world occur some animals have some level of cortex. The occipital (lower part of the temporal) lobes are devoted to vision. Primary visual cortex is directly related to sight and damage to it produces a hole in the persons field, a scitoma. Association cortex in this area performs the function of providing an interface between visual input and memory, allowing one to categorize visual images. Damage can lead to agnosis, the inability to name common objects. Most of the temporal lobe is devoted to audition. Primary auditory cortex is mostly hidden from view, lying on the inside to the upper temporal lobe. Damage to this leads to hearing problems.
