Steroid-induced plasticity of neural circuits to control reproductive and ingestive behaviors.
Neuroanatomical analysis, cell culture, western blot analysis, behavioral molecular pharmacological analysis.
Our research focuses on the cellular and molecular effects of steroids on brain networks that modulate behaviors such as mating and ingestion. To study these behaviorally-relevant neuro-hormonal interactions, a multidisciplinary approach is required. Thus, techniques ranging from behavioral analysis, immunocytochemical localization of peptide and steroid receptors, transneuronal tracing, and confocal analysis of cell morphology are employed.
