New paper out in J. Neuro! We used MEG and pattern classifiers to ask: if a memory is reactivated in the brain, does that mean you'll recall it? Short answer: no. www.jneurosci.org/content/46/1... Read on for the details! [1/7] #neuroscience #memory

Alpha Oscillations Track the Projection of Reactivated Memories into Conscious Awareness

By definition, episodic memory is a conscious phenomenon. Memory traces reactivated by the hippocampus and reinstated in the sensory cortices need to enter conscious awareness for them to be re-experi...

🧠 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! rdcu.be/eui9l

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...

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. Thread below. www.biorxiv.org/content/10.1...

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...

New manuscript published! ✍️👀 Concept neurons evolve from index neurons through overlapping memories. Check it out here: www.cell.com/trends/cogni... 1/15

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...
