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.

The direction and timing of theta and alpha traveling waves modulate human memory processing To support a range of behaviors, the brain must flexibly coordinate neural activity across widespread brain regions. One potential mechanism for this coordination is a traveling wave, in which a neura...

this is really cool, Earl! We saw something similar in humans. It was mentioned in this preprint, Figures 5&6. But unfortunately this result didn't make it into the final version of the paper. www.biorxiv.org/content/10.1...

Please come to our Wave Club meeting tomorrow, April 1, at 12pm ET!

Our presenter is Dr. Jon Kleen (UCSF), who will discuss traveling waves in the human hippocampus from microgrids. All are welcome! Register here: forms.gle/5Q4CPqTHAchH...
