Quizplus · Accepted Answer

Stereognosis is the ability to recognize an object through touch and manipulation. Tactile agnosia, an inability to recognize objects by touch, suggests a parietal lobe lesion. Graphesthesia tests the patient's ability to identify the figure being drawn on his or her palm. The vibratory sense uses a tuning fork placed on a bony prominence. Two-point discrimination uses two sharp objects to determine the distance at which the patient can no longer distinguish the two points. The extinction phenomenon tests sensation by simultaneously touching bilateral sides of the body with a sterile needle.
