A patient has coherent speech but the words are illogical. Which part of the brain has been affected?
a. The cerebellum c. The Wernicke area
b. The Broca area d. The hypothalamus
C
The Wernicke area (Brodmann area 22) is partially located within the parietal lobe and partially in the temporal lobe, most commonly on the left side of the cerebral cortex. This area is concerned with reception of written and verbal language and includes many intricate connections to other parts of the brain associated with auditory and visual functions, cognitive appraisal, and expressive language. Injury to this area of the brain may result in disability ranging from minor receptive language dysfunction to receptive or fluent aphasia, in which expressive language function remains but is illogical in content or a "word salad."
