What symptom is associated with the parietal lobe of the cerebral cortex?

• A. Emotional Lability
• B. Touch Perception
• C. Visual Agnosia
• D. Broca's Aphasia

Answer: (B)

Touch perception is primarily associated with the parietal lobe of the cerebral cortex because this region of the brain processes sensory information related to bodily sensations, including touch, pressure, pain, and temperature. The parietal lobe integrates sensory input from various parts of the body and is crucial for spatial awareness and the manipulation of objects. Damage to this area can result in deficits in the ability to perceive touch or to accurately identify the location of sensations. In contrast, emotional lability is more related to the involvement of the frontal lobe and limbic system, which play key roles in emotional regulation. Visual agnosia, characterized by the inability to recognize objects despite intact vision, typically arises from damage to the occipital lobe or the pathways connecting it to the parietal lobe. Broca's aphasia, related to difficulties in speech production, is associated with damage to the Broca area in the frontal lobe, highlighting the specific and varied functions of different brain regions in relation to sensory and cognitive processes.
