STEREOGNOSIS

'Stereognosis' is the ability to perceive the form of an object by using the sense of touch. This sense, along with tactile spatial acuity, vibration perception, texture discrimination and proprioception, are mediated by the Dorsal Column-Medial Leminiscal system of the Central Nervous System. According to the GP Notebook at http://www.gpnotebook.co.uk, stereognosis is a higher cerebral associative cortical function.
