Research Interests:

Our laboratory's major interest is in determining the neural mechanisms responsible for conveying information about painful and itch-producing stimuli from the spinal cord to the brain. In recent years, we have been interested in the mechanisms underlying the relief from itch produced by scratching and how morphine induces itching.

In our studies, we use several techniques. Physiologically, we examine the responses of individual neurons that form these projections to painful and itch-producing stimulation of the skin and noxious stimulation of visceral tissues. In addition, we use a number of anterograde and retrograde tracing techniques to examine these projections and immunocytochemical techniques to determine the neurotransmitters, receptors or channels that may be involved.
