What is Anominal aphasia is due to defect in and explain in detail?
Wernicke's speech area, is one of the two pas of the cerebral coex that are linked to speech (the other is Broca's area). It is involved in the comprehension of written and spoken language (in contrast to Broca's area that is involved in the production of language). It is traditionally thought to be in Brodmann area, which is located in the superior temporal lobe in the dominant cerebral hemisphere (which is the left hemisphere in about 95% of right handed individuals and 60% of left handed individuals). Damage caused to Wernicke's area results in receptive, fluent aphasia. This means that the person with aphasia will be able to fluently connect words, but the phrases will lack meaning. This is unlike non-fluent aphasia, in which the person will use meaningful words, but in a non-fluent, telegraphic manner. Ref Harrison20th edition pg 2756
