Research Interests

Steroid hormones influence diverse physiological functions in vertebrate animals. The mechanisms by which steroids reach target tissues in an active form are equally diverse. We are interested in determining the mechanisms through steroids are made available to target tissues, principally the brain. We study steroid biosynthesis in steroidogenic organs as well as steroid metabolism in target tissues, especially as these events relate to brain function. This can involve complex interactions between gonadal and adrenal activity, as well as anabolic and catabolic enzyme action in discrete regions of the brain. Currently, I am examining these properties in songbirds to determine how steroids influence the development of the neural circuitry that controls singing behavior, regulate adult song behavior and influence neural circuits involved with memory. We study enzyme activity in whole tissues, cellular organelles, or in specific cell types grown in culture using radioenzymatic assays where radiolabled products are isolated by thin layer-chromatography or HPLC. We study enzyme expression using immunohistochemistry and in situ hybridization analyses. We evaluate neuroanatomial effects of steroids using standard histological procedures and light microscopy.
