Document Summary
Damage to the area posterior to wernicke"s area (temporal-occipital-parietal area) produces a disorder called transcortical sensory aphasia. A direct connection between these two areas enable patients with transcortical sensory aphasia to repeat words that the cannot understand. How do we convert our thoughts (or perceptions) into words? the meanings of words are our memories of objects, actions and concepts associated with them. Memories of words are stored in different regions of the association cortex, not the speech areas first we must recognize the sequence of sounds (the auditory association cortex is activated). Next, we activate the memory that constitutes the meaning of the word. Damage to the left auditory association cortex causes autotopagnosia, the specific inability to name body parts but no impairment in understand the meaning of other words. Repetition: conduction aphasia the arcuate fasciculus conveys information about sounds of words but not their meanings. A tumor is an uncontrollable growth of cells that serves no useful function.
