Damage limited to Wernicke's area of the brain will most likely cause which of the following problems?
Inability to understand what others are saying
Behavioral and personality changes
Loss of peripheral vision in both eyes
Inability to walk and pick up heavy objects
The Correct Answer is A
A. Inability to understand what others are saying: Wernicke’s area is the primary center for language comprehension located in the posterior superior temporal gyrus. Damage here results in receptive aphasia, where auditory input cannot be decoded. Speech remains fluent but is often nonsensical.
B. Behavioral and personality changes: These symptoms are associated with the prefrontal cortex of the frontal lobe, which manages social conduct. Wernicke’s area is specialized for linguistics and does not regulate temperament or behavior. It is a sensory-linguistic processing center.
C. Loss of peripheral vision in both eyes: Visual field deficits result from damage to the optic radiation or the primary visual cortex in the occipital lobe. While the temporal lobe houses some visual fibers, Wernicke’s area specifically does not. Vision remains intact in isolated aphasia.
D. Inability to walk and pick up heavy objects: Gross motor functions are controlled by the primary motor cortex and the cerebellum. Wernicke’s area is a sensory association area that does not govern descending motor pathways. It does not interfere with physical strength or gait.

Correct Answer is C
Explanation
A. Frontal: This anterior region governs executive functions, motor control, and personality. It does not contain the primary sensory architecture for auditory perception. Damage here typically manifests as behavioral changes or motor deficits rather than hearing impairment.
B. Occipital: This posterior lobe is strictly dedicated to the processing of visual stimuli. It receives input from the lateral geniculate nucleus to interpret sight. It possesses no functional pathways for the reception or integration of acoustic information.
C. Temporal: The superior temporal gyrus contains the primary auditory cortex, which receives sensory input from the ears. This region is responsible for perceiving sound frequency and pitch. Injury to this area directly results in auditory processing deficits.
D. Parietal: This lobe is primarily responsible for integrating somatosensory information, including touch, pressure, and proprioception. While it assists in spatial awareness, it is not the primary site for hearing. It lacks the specialized auditory receptive fields.
Correct Answer is D
Explanation
A. neither side of the body.: Cerebrovascular accidents involving the motor cortex or internal capsule almost always produce observable motor deficits. Absence of weakness would suggest a very small or non-motor area infarct. It is not the typical clinical presentation.
B. the left side of the body.: Ipsilateral weakness is rare because motor pathways undergo decussation in the medulla oblongata. A left-sided brain lesion affects the muscles on the opposite side. This does not follow the standard anatomical rule of motor control.
C. both sides of the body.: Bilateral paralysis usually indicates a brainstem injury or a spinal cord lesion rather than a hemispheric stroke. A single-sided cortical infarct is limited in its motor distribution. It affects only one half of the body.
D. the right side of the body.: Upper motor neurons from the left motor cortex cross over at the pyramidal decussation to control the right side. Consequently, damage to the left hemisphere results in contralateral hemiparesis or hemiplegia. This is a fundamental neuroanatomical principle.
