Growing evidence indicates a role for the brain in directly regulating blood glucose, alongside the pancreas. This is particularly interesting given its more obvious role in guiding behavior – when, what, and how much we eat, and whether we exercise (and for how long).

We are motivated by the hypothesis that the brain contributes to blood glucose regulation in a predictive way. With access to both external cues (such as the appearance, smell, and taste of food), internal signals related to nutrient intake, and information about the body’s own actions and energy use, the brain is uniquely positioned to act as a proactive glycemic controller.

Glucose forecasting networks

We recorded from over 18,000 neurons while simultaneously recording blood glucose levels to identify glucose-coding neurons across the brain. Publication and dataset coming soon!

A collaboration with the Campos Lab at UW developing a foundational model to map any mouse image onto a canonical 3D surface. Publication and model launch coming soon!

Approach To study how the brain supports glycemic control, we combine state-of-the-art systems neuroscience approaches in mice, including large-scale neural recordings with Neuropixels probes, continuous glucose monitoring, computational analysis, and self-supervised behavioral analysis.

We first identify brain networks that forecast blood glucose levels and examine how these networks also represent other sensory and behavioral variables, such as taste. We then test how these network coding properties change in disease models. Our goal is to build a spatiotemporal map of how disease affects glycemic control networks and to identify therapeutic strategies that help restore healthier patterns of brain activity.

Multimodal modeling

Our goal is to leverage behavior as a unifying feature to unite neural activity and physiological measurements across diverse experimental conditions and disease states.

Forecasting changes during disease
Forecasting changes during disease

We’re collaborating with other labs at UWMDI to examine how neural forecasting of blood glucose changes as metabolic disease develops – and whether existing and novel therapies revert towards a healthier state.

Sensory routes and glucose predictions

We’re testing how different taste and gut-derived sensory modalities integrate with external information to build glycemic predictions.
