Twenty years ago, on this day in 2006, Allen Institute for Brain Science announced the completion of our inaugural project: a web-based, 3D map of gene expression in the mouse brain providing scientists with a level of data previously not available. #openscience

Please share--the Shansky lab is currently recruiting at all levels to work on an NIH-funded project investigating sex differences in the neural circuits that drive defensive behaviors. The official job ad isn't yet up, but interested folks can contact me as instructed here www.shanskylab.com/join

So grateful to @thetransmitter.bsky.social for the opportunity to talk about a paper that truly shaped how I think about my science by @fowleruci.bsky.social and @paulkennyphd.bsky.social! They helped make causal sense of the association that people call “Mr. Big“ in the context of 🚬!

I'm thrilled to share our recent publication “Overlapping representations in the ventral hippocampus support rapid fear memory retrieval” www.nature.com/articles/s41... We asked, what is the moment-to-moment link between HPC spatial representations, memory retrieval, and fear behaviour?

Overlapping representations in the ventral hippocampus support rapid fear memory retrieval - Nature Neuroscience
Fear learning increases the similarity of threatening and neutral context representations in ventral CA1, which may enable faster reinstatement of threat memories, compared to dorsal CA1.

Our new review is out now on the ventral hippocampus, highlighting a large body of recent work, from the information it represents to how internal state shapes its activity to how its circuits influence behavior.

Our paper is out today!!! (not an April fool's day joke) Congrats to authors @azulsilva.bsky.social, @belalima-paiva.bsky.social, Ele Pronier, and mostly to the amazing scientist and human being who led this project @facuumm.bsky.social #neuroskyence #hippocampus www.nature.com/articles/s41...

Dorsoventral hippocampus neural assemblies reactivate during sleep following an aversive experience - Nature Neuroscience
Synchronization of sharp-wave ripples across the dorsoventral hippocampus during sleep supports coordinated reactivation that represents negative experiences more faithfully than positive ones.

Out now in Nature from @behrenstimb.bsky.social and crew: www.nature.com/articles/s41... Understanding this kind of schematic pattern learning and transfer will be key, IMO, to moving towards models of what we might call "higher-order cognition" or "reasoning". 🧠📈 🧪

Super excited to share our first preprint of work from the lab! We monitor and manipulate the CA1 representation of mice exploring a multicompartment environment to contrast geometric vs. predictive theories of cognitive mapping. TLDR: All signs point to a predictive theory! tinyurl.com/yeyv5p3x
