The dual-phase experience of acute pain is mediated by two types of primary afferent nerve fibres that transmit electrical impulses from the tissues to the spinal cord via the ascending nerve tracts. |

The cortex, meanwhile, sends information about the movement to various afferent neurons that are about to receive information from receptors in the body parts where the movement is about to begin. |
|
Although pain arises from very hot and very cold stimulation and with intense forms of mechanical stimulation, this occurs only with the activation of afferent nerve fibres that specifically report noxious events. |
|
However, damage to the peripheral nerves can result in 'deafferentation' with sprouting of the surviving afferent axons and the development of aberrant connections in the spinal cord. |
