Research InterestsThe laboratory
Mechanisms of neural and endocrine stress responses are the focus of our laboratory. Of special interest are how and why individuals differ, and how responses are characterized temporally. Also of interest are the relationships between stress, biological rhythms, and reproduction. The connection between neural and endocrine responses and variability in the magnitude and way in which individuals respond to and cope with stress behaviorally are what are investigated. There are differing reactions to stress among individuals, including responses of many different hormones and neurotransmitters. We are interested in elucidating the mechanisms by which experience modulates the responsiveness of neural and hormonal stress responses. These studies include measuring behaviorally stimulated changes in biogenic amines by HPLC using microdialysis and brain punch microdissection; mapping neurotransmitters, neuroactive peptides and receptors in the brain immunohistochemically; and relating physiology and anatomy to behavior, ecology and evolution. To study these mechanisms we utilize vertebrate model systems, especially the lizard Anolis carolinensis.
