Research Overview
Our lab is focused on understanding the cognitive, neural, and computational mechanisms underlying self-regulatory control and identifying how these processes go awry in eating disorders. We are particularly interested in identifying how changes in states (internal/motivational or external/environmental) may abnormally influence control-related learning and decision-making in individuals with binge eating, purging, and extreme dietary restriction. We leverage a multi-modal approach that integrates neuroendocrinology, neuroimaging, and computational modeling, as well as experimental tasks from cognitive neuroscience and neuroeconomics. Our ultimate goal is to identify precise targets for new interventions and predictors of who will benefit from which treatments.
Some of the complex questions we’re exploring include:
How can seemingly incompatible characteristics, such as out-of-control impulsivity and compulsive perseverance, co-occur in individuals with eating disorders?
Do the brains of people with eating disorders process and learn about emotions, satiety, and other body-state signals very differently than the brains of people without eating disorders? If so, how does that impact subsequent decision-making?
Could both willingness and ability to control behavior and emotions be altered in people with eating disorders?

Current Projects
Several of our studies aim to clarify how and by what mechanism cognitive control fluctuates across fasted and fed states in bulimia nervosa, potentially perpetuating the cyclical nature of the disorder. In addition, we are training individuals to change their own prefrontal cortex activation with a portable imaging technology called fNIRS to mechanistically test the hypothesis that symptoms of bulimia nervosa are perpetuated by blunted activation in cognitive control circuits during eating; therefore, neurofeedback-based modulation of this activation will improve these symptoms by improving cognitive control. Finally, we are testing whether abnormal connectivity within and between brain circuits during decision-making could explain why binge-eating episodes are both impulsively initiated and inflexibly persistent, as well as promote more severe forms of binge-eating disorder.

Neurofeedback Treatment for Bulimia Nervosa
This study examines whether training people with bulimia nervosa to use certain thought patterns to increase their own brain activation in real-time, called “real-time neurofeedback,” can help reduce their eating disorder symptoms. By participating in this study, you or someone you care about could help advance research on treatment for bulimia nervosa.
If you (or if you know someone who) binge-eat and purge (e.g., self-induced vomiting, misusing laxatives or diuretics or diet pills, exercising intensively and compulsively, or fasting) to control your shape or weight, and are interested in learning more about our research study, please continue to read the study details below.
WHAT IS NEUROFEEDBACK?
Neurofeedback is a non-invasive brain training that is administered via a functional near-infrared spectroscopy (fNIRS) device that records and displays your brain activity in real-time. The purpose of this training is to help you train your brain function. Specifically, we are interested in learning whether this type of brain training will help people with bulimia nervosa reduce their eating disorders symptoms.
WHAT IS FUNCTIONAL NEAR-INFRARED SPECTROSCOPY (fNIRS)? IS IT SAFE FOR ME?
fNIRS is a brain imaging technology that detects brain activity in different areas of your brain using infrared technology. When you are doing an activity and use specific parts of your brain, the blood flow to those brain areas is higher than the blood flow to other areas of your brain. The fNIRS device can detect the “color” of the blood that flows into these specific brain areas; the darker the color, the more active the brain areas are.
This technology does not involve any magnets or radiation and it’s even been used to study babies.
WHAT’S INVOLVED IN THIS STUDY?
- Phone interview to confirm qualification (~15-20 minutes)
- Clinical interviews remotely or at Mount Sinai (~2.5 hours)
- In-person screening and computer tasks (~1.5 hours)
- A neurofeedback session (~1.5 hours)

- A follow-up remote assessment (~1 hour)
WHY PARTICIPATE?
- Reimbursement for travel.
