Tactile induced analgesia : ウィキペディア英語版 | Tactile induced analgesia
''Tactile induced analgesia'' is the phenomenon where concurrent touch and pain on the skin reduces the intensity of pain that is felt. == Somatosensory afferent fibres ==
There are four main types of sensory fibres responsible for somatosensation: Aα, Aβ, Aδ and C fibres (more details can be found at the axon page). The Aβ fibres are from cutaneous mechanoreceptors and respond to touch stimuli; the Aδ and C fibres are nociceptor afferents which respond to painful stimuli. The touch fibres have a larger diameter than the pain fibres, which means that they transmit their action potentials much faster than the smaller diameter fibres.
