'''''Nociception''''' is the process of neurotransmission that transmits and processes information relating to tissue damage. It originates from sensory receptors known as ''nociceptors''. ''Pain'', on the other hand, is a conscious experience arising from nociception. It has previously been described as:

'''''Pain''''', on the other hand, is a conscious experience arising from nociception. It has previously been described as:

# "An unpleasant sensory or emotional experience associated with actual or potential tissue damage." (International Association for the Study of Pain, 1978).

# "An unpleasant sensory or emotional experience associated with actual or potential tissue damage." (International Association for the Study of Pain, 1978).

# "A multidimenstional experience produced from characteristic neurosignature patterns arising from nerve impulses generated by a widely distributed neural network located in the brain. These neurosignatures can be generated independently of somatosensory input". (Melzack, 1999).
