Our main focus is the neural mechanisms underlying stress-related physiology and emotional behavior with a focus on the role of serotonergic systems. Current projects address four main topics:
- Mechanisms underlying control of acute and chronic anxiety states - with a focus on interactions among corticotropin-releasing factor (CRF) and CRF-related neuropeptides
- Effects of peripheral immune activation on serotonergic systems, physiology, and emotional behavior - with a focus on the microbiome-gut-brain (MGB) axis
- Effects of thermal signals on serotonergic systems, physiology, and emotional behavior
- Effects of glucocorticoid hormones on serotonergic systems, physiology, and behavior
- Director: Christopher A. Lowry, PhD
- Post-doctoral Fellow: Cristian Zambrano, PhD
- Graduate Students: Kelsey Loupy; Flux Caruso; Christine Foxx; Saydie Sago; Kristin Cler
- Professional Research Assistant: Ahmed Elsayed, BA
- Undergraduate Students: Madi Baca, Lauren Milton, Andrea Arnold, Jessica Stewart, Amalia Luthens, Stephanie Salazar, Kyo Lee, Brandon Marquart, Evan Holbrook, Chang Liu, Evan Schaefer, Drake Kienzle, Kourtney Creaney, Brooke Elam
