Wernicke's area is usually located in the back part of the temporal lobe, although exact locations can vary. It is most frequently found in the left hemisphere of the brain. When Wernicke’s area is damaged, a language aphasia can result.This type of aphasia is known as Wernicke's aphasia, but is also sometimes referred to as fluent aphasia, sensory aphasia, or receptive aphasia. Language development or usage can be seriously impaired by damage to this area of the brain.
