A subtest for sensory perception where the examiner writes numbers or letters on the patient's palm with a dull pointer to test for recognition is known as what?
Explanation
Graphesthesia is a test of cortical sensory function, specifically the ability to recognize writing on the skin purely by the sensation of touch. It assesses the integrity of the parietal lobes.
