Research Interest(s):

I am a neuroscientist. I study the brain, the organ of behavior. Much of my past research was aimed at understanding the neural control of movement and somatosensation. I used primarily neuroanatomical techniques to reveal the organization of sensorimotor pathways in the cerebral cortex, thalamus, basal ganglia, cerebellum, and spinal cord of mammals. More recently, my students and I have been conducting neuropharmacological studies of valerenic acid (VA), a plant-derived compound reported to reduce anxiety. To test the effectiveness of VA, we have been conducting behavioral experiments in mice.
