Haptic perception

Haptic perception (Greek: haptόs "palpable", haptikόs "suitable for touch") means literally the ability "to grasp something", and is also known as stereognosis.

[11] The following exploratory procedures have been identified so far: Thus gathered object or subject properties are size, weight, contour, surface and material characteristics, consistency and temperature.

Examples of medical conditions that can cause neuropathies are diabetes mellitus, chronic kidney disease, thyroid dysfunction (hyper- and hypothyroidism) as well as hepatitis, liver cirrhosis and alcohol dependency.
