My research update routine:
To keep up with new papers, I bookmark them throughout the week. On weekends, I open them all in Safari, run a script to grab the links, and then give that list to Gemini Deep Research for quick, deep-dive summaries and even linked, related papers.

Dynamic coding and sequential integration of multiple reward attributes by primate amygdala neurons - Nature Communications
The amygdala assigns value to stimuli, yet how its neurons process different value components is unclear. Here the authors show that monkey amygdala neurons respond to different reward attributes and ...

Yup - or single-purpose/reductionist [models of] behaviors when the system must manage multiple goals IRL. If we race to the bottom with low-D tasks, should we then marvel at how scalar/categorical the response? elifesciences.org/articles/908...

Hippocampal output suppresses orbitofrontal cortex schema cell formation - Nature Neuroscience
Inactivation of the ventral subiculum does not change existing schema cells in the orbitofrontal cortex (OFC) but aids their formation during new learning. This challenges the idea that the OFC relies...

Check out this cool work from my superstar student Elie developing a new dimensionality reduction algorithm that compares two conditions! It works on many types of data
Does your research involve comparing experimental conditions? Then our latest publication is for you: We developed generalized contrastive PCA (gcPCA), a tool for comparing high-dimensional datasets. 🧠📊 doi.org/10.1371/journal.pcbi.1012747
This tool was born out of necessity, here is the story. 🧵

After careful curation of single units from CA1 and connected structures, we identified cell assemblies - repeated patterns of synchronous firing (typically N~100, some approaching 300). Some assemblies were more active in NEW trials, others OLD. But did either or both groups reactivate in sleep?

Using thread, the artist Sonya Clark has stitched a map of the world on a piece of wood, but then woven the individual threads into a single pony tail, visualizing our connected humanity.
