somatic sensation
... Following tissue damage and nociceptor stimulation, the threshold for subsequent stimulation is decreased and thus, sensitivity to that stimulus is increased. This process is termed “hyperalgesia”. In some cases, hyperalgesia can induce a change in nociceptor sensitivity from unimodal to bimodal, e. ...
