Neuropixels in human hippocampus (anesthesia). Neurons show strong tracking of the auditory envelope of sound cues. No evidence for sound-evoked spatial reactivation. Come and have a look! Poster attached.

Despite recent criticism from Quiroga to our claim that Concept Neurons emerge from Conjunctive Coding Neurons we claim: “And yet, the hippocampus codes conjunctively!”.
We hope it sparks a smile (and maybe a few debates).

🧠 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!

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.

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...

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...
