Question

Quizplus · Accepted Answer

Fluent aphasia, also known as Wernicke's aphasia, is due to damage to Wernicke's area in the temporal lobe, which is responsible for language comprehension. This results in smooth but meaningless speech and difficulty understanding spoken or written language. Damage to Broca's area in the frontal lobe, which is responsible for speech production, would result in non-fluent aphasia, in which the victim can understand language but has difficulty speaking. The prefrontal cortex is responsible for executive functions such as decision-making and planning, and damage to the corpus callosum would impair communication between the two hemispheres of the brain but would not necessarily affect language comprehension or production.
