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...

If we could record all neurons we still would not know how they communicate: medium.com/@kording/628...
Would recording all neurons reveal their interactions?
For years, I was captivated by the idea that if we could record the activity of every neuron in the brain, we’d eventually crack the code…

I am incredibly proud to share my first, first-author paper as a postdoc with @benhayden.bsky.social . How does the human hippocampus, known for encoding concepts, represent the meanings of words while listening to narrative speech?

Incorporation of complex narratives into dreaming
Reactivation of waking neuronal activity during sleep holds a functional role in memory consolidation. Reprocessing of daytime memory in dreams might aid later memory performance in a similar way. Num...

Wow, non-invasive stimulation of the human hippocampus & entorhinal cortex during VR-navigation inside the MRI scanner! Impressive technical achievement and interesting result. By Beanato et al. www.science.org/doi/10.1126/...
Noninvasive modulation of the hippocampal-entorhinal complex during spatial navigation in humans
Transcranial temporal interference stimulation allows noninvasive modulation of the hippocampus leading to better navigation.

Excited to share our preprint "Fast-timescale hippocampal processes bridge between slowly unfurling neocortical states during memory search" 🧠✨ We leverage iEEG to elucidate the fast neural mechanisms by which long multimodal narratives are unfurled in continuous memory-search tinyurl.com/wjkr3dvf
Fast-timescale hippocampal processes bridge between slowly unfurling neocortical states during memory search
Prior behavioral work showed that event structure plays a key role in our ability to mentally search through memories of continuous naturalistic experience. We hypothesized that, neurally, this memory...
