Characterization of itch-related behavior and physiology of trigeminothalamic tract neurons in rats, including the role of opioids
Undergraduate Institution and Major/Degree:
B.A., Biology: Neuroscience, Northwestern College, IA 2008
Our lab studies the transmission of itch and pain information within the central nervous system. I have been characterizing itch responses in thalamic-projecting neurons in the spinal trigeminal subnucleus caudalis of rats. Currently, I am examining the roles of opioid receptors in mediating responses to itch in the trigeminal system. I am also performing parallel experiments to determine effects of opioid drugs on scratching behavior in rats.
