Question

Quizplus · Accepted Answer

Stimulation of the left parietal cortex is known to cause sensations on the opposite side of the body, i.e. the right half of the body. Therefore, the patient is likely to experience touch sensations somewhere on the right half of their body. Option B is incorrect because the parietal cortex is primarily responsible for processing touch and spatial information, not visual information. Option C is incorrect because the parietal cortex is not involved in processing auditory information. Option D is incorrect because the stimulation of the parietal cortex is unlikely to cause movements of the body.
