An update on the spinal and peripheral pathways of pain signalling
SG Lechner - e-Neuroforum, 2017 - degruyter.com
Painful or potentially tissue-damaging stimuli are detected by primary sensory afferents that

Role of RVM neurons in capsaicin-evoked visceral nociception and referred hyperalgesia
Most forms of visceral pain generate intense referred hyperalgesia but the mechanisms of
this enhanced visceral hypersensitivity are not known. The on-cells of the rostral …
