Dr. Rebecca Klatzkin: Behavioral Neuroscience Lab

Dr. Klatzkin’s research program broadly investigates stress-related psychopathology in women. Specifically, the current goal of the Behavioral Neuroscience Research Lab is to understand the psychological and physiological factors contributing to stress-induced eating.

Stress is associated with a myriad of negative physical and mental health consequences, 包括肥胖和饮食失调. Understanding the psychophysiological mechanisms driving the stress-eating relationship is critical in order to strengthen prevention and treatment efforts for at-risk individuals; yet the mechanisms by which stress impacts eating are not fully understood.

The hypothalamic pituitary adrenal (HPA) axis is a central component in the regulation stress-induced eating, releasing cortisol in response to stress and, consequently, 增加食物消费. However, cortisol has also been associated with eating less following stress and, although the majority of women tend to be stress over-eaters, many decrease their food intake following stress. These conflicting findings indicate that various individual difference factors interact with the acute stress response to impact food consumption. The Behavioral Neuroscience Research Lab is dedicated to understanding how the psychophysiological mechanisms underlying stress-induced eating depend on various individual differences such as obesity, binge eating, 皮质醇应激反应, 慢性压力.
