Electrophysiology and neuroanatomy of central neurons mediating the control of reproductive and pelvic organs; normal neural mechanisms and plasticity following injury and/or chronic pain.
- Autonomic Nervous System Dysfunction Following Spinal Cord Injury: Research is focused on animal studies exploring the distribution of ascending and descending spinal pathways that sub-serve sexual, bladder and bowel functions. A multidisciplinary approach involves parallel electrophysiological, neuroanatomical and behavioral studies.
- Central Neural Mechanisms Underlying Reproductive Organ Sensation: Research is focused on studies in male and female rats examining the central processing of information arising from stimulation of the reproductive organs. The impact of varying levels of gonadal hormones on neuronal response properties and characteristics is being explored.
- Chronic Pain Following Spinal Cord Injury: Research is focused on understanding the central neural mechanisms underlying the development and perpetuation of allodynia at and just above the segmental level of a spinal cord injury (at level allodynia). Potential gender differences in the responses to a variety of stimuli are of great interest.
