Nociceptive visceral afferents of the vagus (like those visceral conducted by the medulla) mostly reach the solitary nucleus. Pain signals from the vagus also direct a tract towards PA5 and SC5 in a lateral pathway (homologous to the solitary-trigeminal tract in the rat) (Gwyn et al., 1985; Menetrey et al., 1992; Gieroba & Blessing, 1994; Yousfi-Malki & Puizillout, 1994).
It is also interesting that synapsis afferents reaching the solitary nucleus happens again to the PA5 connecting reciprocally ipsi- and contra-laterally with solitary, parabrachial, dorsal vagus, caudal medullar dorsal horn, C1 and C2 ventral medullar horns (the accessory's spinal nucleus portion) and SC5 nuclei (Jou et al., 2002).
Abdominal visceral "pain" afferents (stretching, heat, ischemia, laceration), as well as being conducted by the sympathetic system, usually and mostly travel via the vagus nerve, synapsis happening in the inferior ganglion and converging (as well as the solitary nucleus) towards PA5 and SC5 nuclei.
