1/ How does deep sleep reshape our memories? Our new study shows that slow-wave sleep (SWS) reorganises episodic memory networks, shifting recall from the parietal cortex to the anterior temporal lobe (ATL). With Polina Perzich and @bstaresina.bsky.social . A thread below👇

We asked a simple-but-big question:
What changes in the brain when someone becomes an expert?
Using chess ♟️ + fMRI 🧠 + representational geometry & dimensionality 📈, we ask:
1️⃣ WHAT information is encoded?
2️⃣ HOW is it structured?
3️⃣ WHERE is it expressed?

The method generates descriptive text of what we perceive and recall from brain activity — a linguistic interpretation of nonverbal mental content rather than language decoding.

The effect presumably comes from the absence of S-cones in the fovea.

1/8: How do human neurons encode meaning?
In this work, led by Katharina Karkowski, we recorded hundreds of human MTL neurons to study semantic coding in the human brain:

#Decoding studies often rely on training in one (visual) condition and applying it to another (e.g. rest-reactivation). However: How well does this work? Show us what makes it work and win up to 1000$!

I argued that our overly specialized, modular approach to studying the brain has given us a simplistic view of readout.

Different representational formats of a memory can be used at different times or in different contexts, and draw on different neural representations.

We built an RNN🤖 with key-value episodic memory that learns causal relationships between events and retrieves memories like humans do!

Excited to share our latest work on alpha/beta activity, eye movements, and memory.
Across 4 experiments combining scalp EEG/iEEG with eye tracking, we show that alpha/beta activity directly reflects eye movements, and only indirectly relates to memory.
👇 Highlights (1/7):
