How are different emotions encoded in the brain? In this study we reveal that sexual arousal and aggression using a common neural code, revealing a glimpse of a potential principle in the brain for how emotions work!

How do neural dynamics emerge within neural networks? By combining our ability to 'write in' neural signals and model neural circuits using machine learning in real time, we reveal how a network mechanism called a line attractor emerges within neural circuits!

How is an emotion encoded in the brain? In this study, we introduce a completely new framework to think about emotions as the emergent properties of brain networks and their underlying physics! Turns out, getting angry is linked to neural activity flowing along a 'pipe' in your brain!

What mechanisms regulate long-time scale persistence in the brain important for emotions? We find a surprising connection between emergent attractor dynamics important for aggression and neuropeptides, opening up important avenues for mechanisms and therapeutic approaches to alter network dynamics!

Are neurons the only computing element in the brain? In this study, we found an unexpected role for microglia to act as brakes on neural activity and contribute to computation in several brain regions. This was collaborative work with Viviana Gradinaru's lab and Anne Schaefer's lab.

What can we learn about internal states by looking at some of the simplest organisms? My colleague Brady Weissbourd created genetically modified jellyfish where we could record neural activity and we found surprising structure in this activity!

We mostly think of neurons as releasing a single transmitter, but in some systems, they paradoxically release opposing transmitters. By looking in the claustrum, a poorly studied structure linked with attention, we found evidence for a potential logic for this co-release. Read the preprint while the paper is in press!
