The Temporal Cortex :: Brain Neurology Essays

The Temporal Cortex The worldly cortex, also know as the temporal lobes, is the part of the communicative cortex in the leaveover and right hemispheres of the mavin lying inside the temples. In general the temporal lobes handle a wide variety of task that are inwrought to every day functioning. Patient him/herselfThe temporal lobes are readily recognizable brain structures with a thumb like appearance when viewed from the side. Their name reflects their mending beneath the temporal bone on the side of the head. In near ways, the temporal lobes are more a convenient fiction than anatomical entities. They share borders with the occipital and parietal lobes, but the precise boundaries are non clearly defined by landmarks. A better definition of the anatomical limits of the temporal lobe would come from thalamic and intracortical projections and a functional analysis of the various subunits at bottom the lobe. Because excision of the anterior temporal lobe is oft en used to help break medically intractable seizure disorders, much of our knowledge of the effects of pervert to this area comes from studies of persons with epilepsy (Encyclopedia of the Human Brain).The functions of the temporal lobe are auditory, ventral opthalmic stream, impact of auditory input, visual object recognition and categorization, long term storage of receptive input, Amygdala (adds affective or emotional tone to sensory input and memories), and Hippocampus (cells code places in space and allow us to navigate space and remember where we are) (www.brain place.com/bp/brain system/temporal.asp).The temporal lobe is separated into two sides dominate and non-dominate. The dominate side of the temporal lobe is usually the left side and is involved in the perception of words, affect language colligate to sounds, sequential analysis, increased blood flow during speech perception, processing details, mean(a) term memory, long term memory, auditory learning, retrieva l of words, complex memories, and visual and auditory processing. A patient who is experiencing dominant temporal lobe problems may be suffering from one or more of the following symptoms decreased verbal memory (words, lists, stories), difficulty placing words or pictures into discreet categories, trouble accord the context of words, aggression internally or externally driven, dark or violent thoughts, sensitivity to slights, mild paranoia, word finding problems, auditory processing problems, reading difficulties, as well as emotional instability (www.brain place.com/bp/brain system/temporal.asp).The non-dominate side of the temporal lobe is usually the
