The gut-brain vagal axis governs mesolimbic dopamine dynamics and reward events
Reward-related processes have traditionally been ascribed to neural circuits centered on the dopamine (DA) system. While exteroceptive stimuli, such as food and drugs of abuse, are well-established ac...

Gave a talk at my parents’ retirement community to describe how science is done, and what is at stake. There was a ton of interest, and anyone can do this. Get the word out about how science affects everyone. I’m happy to share slides with anyone who asks- just get in touch! youtu.be/BY_SFgi-Cig

What if… spontaneous neural activity 🧠 reflects the baseline rumblings of a brainwide dynamical system initialized for learning? We find that the rumblings have macroscopic properties like those emerging from linear symmetric, critical systems 🧵 #neuroscience #neuroAI www.biorxiv.org/content/10.1...

GLP-1 receptor agonists (GLP-1RAs) are transforming the treatment of obesity and diabetes (and more). Our recent pre-print examined next-gen small molecules mimicking GLP-1, using humanized mouse models to uncover how they interact with brain circuits driving food consumption. 1/15
