| Outline of Final Research Achievements |
I have found the followings: first, noradrenaline applied to the acute brain slices containing the central amygdala potently modulated the synaptic transmission. Second, injection of anti-dopamine beta-hydroxylase-saporin into the central amygdala, which resulted in destroying of the noradrenergic fibers in the amygdala, changed in spontaneous pain-related behaviors and the thermal preference. Finally, I have established a system for Cre recombinase-dependent expression of channelrhodopsin in the noradrenergic neurons that would enable light-triggered release of intrinsic noradrenaline in vivo and ex vivo preparations.
