Damage to which brain area can lead to apraxia and difficulty recognizing objects by touch?

• A. Occipital lobe
• B. Parietal lobe
• C. Frontal lobe
• D. Cerebellum

Answer: (B)

Damage to the parietal lobe can result in apraxia and difficulties in recognizing objects by touch due to the lobe's critical role in sensory perception and spatial awareness. The parietal lobe integrates sensory information from various modalities, including touch, and plays a fundamental role in the processing of tactile stimuli. When this area is impaired, an individual might struggle to carry out purposeful movements (apraxia) because their brain has trouble coordinating the necessary motor actions in relation to sensory feedback. Additionally, the parietal lobe is involved in somatosensory processing, which is essential for recognizing objects through touch. This means that if the parietal lobe is damaged, it can disrupt the ability to assess textures, shapes, and sizes of objects, leading to difficulties in tactile recognition. Therefore, damage to this specific brain area would effectively account for the symptoms described in the question.
