Outline of Final Research Achievements |
We have revealed that the granular and dysgranular insular cortices gives off direct, somatotopic projections to the superficial layers of the trigeminal caudal subnucleus which are well known to contain neurons transmitting orofacial pain (Sato et al. 2013, Neuroscience). The present study has for the first time demonstrated that this descending pathway from the insula becomes a feedback pathway to the ascending pathway of orofacial pain through the superficial layers of the trigeminal caudal subnucleus, and that this descending pathway from the insula can make influence (especially inhibitory influence) on the asceding nocicepthve pathway. These data have clearly shown the neuronal mechanisms underlying the strong relationship between the orofacial pain and emotion induced by the pain.
