The research in my laboratory examines the effects of hormones on neural circuitry in the rat brain, particularly the hypothalamus. Estrogen induces neural plasticity in various brain regions, including the hypothalamus, which allows the modulation of reproductive and ingestive behaviors in adult female rodents according to the phase of the estrus cycle. The research in my laboratory capitalizes on multidisciplinary approaches to study these neurohormonal interactions. Techniques range from behavioral analysis, receptor localization, tracing studies, pharmacological analyses, and molecular studies of the regulation of transcription. This research is funded by the National Institute of Health.
