An instrument for determining the acuity of tactile sensitiveness.  

That portion of the nervous system concerned with the sensation of touch. It includes sensory nerve endings (Meissner’s corpuscles, Merkel’s tactile disks, hair-root endings), afferent nerve fibers, conducting pathways in the cord and brain, and the sensory area of the parietal lobe of the cerebral cortex.  

An individual’s ability to accurately identify the site of tactile stimulation (touch, pressure, or pain). Tactile localization is often tested in sensory evaluations following disease or trauma of the nervous system.
