Research Interests

(see also www.iub.edu/~sengelab)

Dr. Sengelaub studies the processes that regulate the structure and organization of both the developing and adult nervous system. Using a variety of species, neural systems, anatomical, and electrophysiological techniques, he addresses the factors which regulate 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. Current projects include ontogeny and hormonal control of sex differences in spinal nuclei, functional and morphological plasticity in hormonally sensitive neuromuscular systems, and examination of the neuroprotective/therapeutic effects of hormones.
