Sensory physiology

The skin's perception of mechanical contact

In sensory physiology, touch is the somatosensory channel by which mechanical contact at the skin is turned into neural signals: specialised mechanoreceptors in the skin respond to pressure, indentation, vibration, and skin stretch, and their firing is relayed to the brain as the felt sense of contact. Adrian and Zotterman's 1926 The impulses produced by sensory nerve-endings recorded the all-or-none impulses of a single sensory end-organ under graded pressure, founding the quantitative study of tactile receptors, and Johnson's 2001 The roles and functions of cutaneous mechanoreceptors maps the main receptor types of the human hand to the distinct qualities of touch they carry. The referent is a perceptual sense grounded in receptor physiology, measured by detection thresholds and discrimination, and it shares nothing with a fencer's scoring hit or a shell command beyond the word.[1][2]
