Outline of Final Research Achievements

We have studied how noradrenergic neurons in the locus coeruleus in the brain stem act on descending antnociception and arousal levels in the brain. We used virus vectors to control noradrenergic neuronal activity by using optogenetic tools. Locus coeruleus neurons were successfully activated by optic stimulation and how the locus coeruleus activation changes nociceptive behaviors and arousal levels was examined. In vivo electrophysiological analysis was also studied, and the descending and ascending neuronal circuits were identified with Immunohistochemical methods.
