Introduction[edit | edit source]
1. Specificity Theory [edit | edit source]
<span />This theory considers pain as an independent sensation with specialised peripheral sensory receptors [nociceptors], which respond to damage and send signals through pathways (along nerve fibres) in the nervous system to target centres in the brain. These brain centres process the signals to produce the experience of pain.[1]
2. Pattern Theory[edit | edit source]
This theory consider that peripheral sensory receptors, responding to touch, warmth and other non-damaging as well as to damaging stimuli, give rise to non-painful or painful experiences as a result of differences in the patterns [in time] of the signals sent through the nervous system.[2]
