Movie-watching evokes ripple-like activity within events and at event boundaries Nature Communications - The neural processes involved in memory formation for realistic experiences remain poorly understood. Here, the authors found that ripple-like activity in the human...

🧠 Paper out!

We investigated how hippocampal and cortical ripples support memory during movie watching. We found that:

🎬 Hippocampal ripples mark event boundaries
🧩 Cortical ripples predict later recall

Ripples may help transform real-life experiences into lasting memories!

Cholinergic blockade reveals role for human hippocampal theta in encoding but not retrieval Cholinergic dysfunction is a hallmark of Alzheimer's disease and other memory disorders. Yet, the neurophysiological mechanisms linking cholinergic signaling to memory remain poorly understood. In thi...

Hi Bluesky! First post here. Kicking things off with a new preprint.

🧠 Using human iEEG + pharmacology, we asked: is hippocampal theta required for retrieval?

Turns out it’s not. Instead, it may reflect a reinstated encoding mode.

On the origin of memory neurons in the human hippocampus The hippocampus is essential for episodic memory, yet its coding mechanism remains debated. In humans, two main theories have been proposed: one suggests that concept neurons represent specific elemen...

New manuscript published! ✍️👀

Concept neurons evolve from index neurons through overlapping memories.

After years of work designing and running this study with a multi-University team, we have our first preprint 🎉🎉 showing how a memorization technique builds neural representations through conjunctive representations! See thread and preprint link ⬇️
