View submission: Can humans sense electric shock?
Yeah, the former is correct. The main afferent fibre for light touch is A-beta. It responds to light touch, vibration and pressure by expressing mechanoreceptors (e.g. Meissner’s corpuscles) that detect changes in skin deformation. They can do this because they have ion channels that open when the skin deforms, which then leads to action potentials.
There's nothing here!
