To clarify the mechanism underlying the link between pain and negative emotion (suffering), we focused on the spino-parabrachio-amygdaloid pathway: 1) Optogenetic activation of the parabrachial-central amygdala pathway alone functions as unconditioned stimulus in Pavlovian and operant conditional learning. 2) This evoked mono- and polysynaptic network-driven activities in the central amygdala neurons, which was potentiated in the persistent inflammatory pain model. And 3) chemogenetic inhibition of GABAergic neurons in the central amygdala in the inflammatory pain model mitigated hypersensitivity and chemogenetic activation of these gave rise to the hypersensitivity in normal rats. These results indicate that this pathway is the primary route for the aversive nociceptive information to activate the limbic system leading to not only the negative emotion but also the elevated sensitivity to potentially harmful events.
