New paper from the lab 🚨
Led by Ali Golbabaei, this study explores the how the composition of prefrontal cortical engrams changes with memory age:

Imagine a brain decoding algorithm that could generalize across different subjects and tasks. Today, we’re one step closer to achieving that vision.

Looking forward to giving a talk on the latest developments in engram research 🧠
The main lecture will be in English, with a part on my own research in Ukrainian.

“If everything is everywhere, why have distinct areas? Here we show that the function of a brain area is more related to how different types of information are combined (formatted) in neural representations than merely whether that information is present.”
New results for a new year! “Linking neural population formatting to function” describes our modern take on an old question: how can we understand the contribution of a brain area to behavior?

Linking neural population formatting to function
Animals capable of complex behaviors tend to have more distinct brain areas than simpler organisms, and artificial networks that perform many tasks tend to self-organize into modules (1-3). This sugge...

Despite its efficiency, the brain is oddly inefficient: requires ~8 hours of sleep for every 16 hours of runtime. We spend a third of our lives recharging.

#IBB shared some highlights from their visit to @sjo09.bsky.social lab. It was rewarding to see how much interest was sparked by #engrams as well as #ML and #NeuroAI 🧠✨

Shoutout to @mhsarikahya.bsky.social & other JF lab members!

Wrapped up 2 intense weeks at #NeuroAI by @neuromatch.bsky.social! 🚀
Our team explored how RNNs encode spatial memory — and found they implicitly learn a discrete spatial layout.

Thanks to my amazing teammates!

@ryanpaulbadman1.bsky.social & Riley Simmons-Edler show–through cog sci, neuro & ethology–how an AI agent with fewer ‘neurons’ than an insect can forage, find safety & dodge predators in a virtual world. Here's what we built

Your brain doesn’t just passively track time ⏳ - it structures it.
In @Science.org we show that activity in 🧠 memory circuits (LEC) drifts constantly, but makes sharp jumps at key moments, segmenting life into meaningful events. (1/2)

Event structure sculpts neural population dynamics in the lateral entorhinal cortex
Our experience of the world is a continuous stream of events that must be segmented and organized at multiple timescales. The neural mechanisms underlying this process remain unknown. In this work, we...

It took me a while, but I can now see a purpose in speaking to the discussion of my departure from Yale for the University of Toronto. Here I address four public framings of last year’s move that arose in recent weeks, which tell us something of our present moment

Learn how the amygdala helps us tell apart friends vs. foes (as reenacted in the photo) and how this ability is shaped by oxytocin signaling and engrams :)

DeepLabCut has demonstrated high performance on professional skiers, but how does it handle snowboarders who spend more time eating snow than riding? 🤭
Despite a very small training dataset, the output is surprisingly promising! @deeplabcut.bsky.social
