  • Neural plasticity
  • Neuroprotective/therapeutic effects of hormones

Dr. Sengelaub studies the processes that regulate the structure of both the developing and adult nervous system, with particular emphasis on structure / behavior relationships. Using a variety of species, neural systems, and anatomical techniques, he addresses the factors that determine neuron number, distribution, morphology, and connectivity in the brain and spinal cord. Processes such as dendritic growth and retraction, and the maintenance of adult neuron morphology after nerve injury or spinal damage are of primary interest. His current projects include ontogeny and hormonal control of sex differences in the nervous system and the therapeutic use of steroid hormones after injury in adulthood.
