Stereognosia is the ability to recognize objects based on mere tactile experience. The postcentral region of the parietal lobe is primarily involved in this ability, in addition to the individual components of the sense of touch. Lesions in these regions can disrupt this ability and cause what is known as astereognosia (stereoagnosia). What is stereognosia? … Stereognosy: Function, Tasks, Role & Diseases
Astereognosia is the inability to recognize shapes by palpation with eyes closed. The cause is damage to the central nervous system, where tactile impressions are processed and made to be recognized. Astereognosia is causally untreatable in most cases and for this reason can usually be alleviated at best by targeted tactile training.

The postcentral gyrus is an area of the cerebrum. It is located in the parietal lobe and plays a role in somatosensory processing. Damage to the postcentral gyrus results in astereognosia, which is reflected as disturbances in touch sensitivity, pain and temperature perception, and vibration sensation and proprioception.
