Research Interests:  Neurobiology - elucidation of the principles by which sensory information is transformed into movement using the simple spinal reflexes in rats.

The overall goal of our laboratory is to elucidate the principles by which sensory information is transformed into movement. More specifically, we investigate simple spinal reflexes in rats. Our research currently has two focuses: 1) The nervous systems of young animals is remarkably sensitive to sensory stimulation. For example, placing a patch over a kitten's eye for as little as one week early in life causes permanent blindness in that eye. Similarly, we have found that a brief injury to the foot of neonatal rats can lead to permanent increases in the rat's pain sensitivity as an adult. Current studies are designed to determine the underlying neural mechanisms and functional significance. Our results may impact the care of premature infants who typically experience pain in the neonatal intensive care unit. 2) When we touch a hot saucepan we rapidly remove our hand to prevent injury. The movement is a spinal reflex known as the flexion withdrawal reflex. Surprisingly, the direction of movement is not always directly away from the injurious stimuli. Our research studies the spatial transformation between stimulus location and movement direction for flexion withdrawal reflexes of the rat tail.
