Neurotensin

Neurotensin (NTS) is a 13-AA neuropeptide expressed throughout the brain and has been shown to play a role in modulating reward and anxiety-like behaviors. We are interested in NTS expressed in several key nuclei, what it is doing there, and what the neurons that express NTS are doing. Our data suggests that NTS expressing neurons in the central nucleus of the amygdala are playing an interesting role in the regulation of alcohol-related behaviors.

Norepinephrine

Norepinephrine (NE) is a catecholamine produced by multiple cell clusters in the pons and medula (as well as sympathetic ganglia and adrenal gland). We are interested in how NE modulates learning and memory, stress responsivity, anxiety, drug and alcohol use, and other behaviors. In particular we're interested in how NE modulates the bed nucleus of the stria terminalis, a component of the extended amygdala receiving the densest NE innervation in the brain!
