I’m excited to share my final co-first author paper from my postdoc in Dan Dombeck's lab! We explored how behavior, senses, and neurons influence how much information in the brain changes over time. www.nature.com/articles/s41... #science #research #neuroscience #hippocampus #placecells

Hippocampal representations drift in stable multisensory environments - Nature

Tracking of individual place cells in mouse CA1 shows that representational drift is not influenced by changes in environment or behaviour, and is lower for more excitable place cells.

Very happy to see a Transmitter (@thetransmitter.bsky.social) piece on our recent work on estrous cycle modulation of hippocampal structure and function. Thanks to Sydney Wyatt (@sydneywyatt.bsky.social) for covering the work and its context: www.thetransmitter.org/neuroendocri...

Spatial learning circuitry fluctuates in step with estrous cycle in mice

Cyclic shifts in estradiol levels coincide with changes in dendritic spine density and the activity of place cells in the CA1 region of the hippocampus, a new study shows.

🚨New paper alert! 🚨 Inactivation of the nucleus reuniens causes relapse of extinguished fear. Here we show this “circuit-induced relapse” depends on hippocampal fear memories and is mediated by hippocampal engrams. Congrats to the team!

Great to see this Tim! Glad that eLife is standing up here. I was worried after HHMI cut their DEI programme. Did you see my article btw? www.thetransmitter.org/policy/scien...

This list has doubled. Who haven’t I found?

go.bsky.app/LdtUYZS I created a starter pack for the growing community of hippocampus physiologists that have joined the great migration. Also included the physiology-adjacent. Tell me who I haven’t found yet
