Thrilled to see our paper published! I’m deeply grateful to the amazing @ggirardeau.bsky.social for trusting me to develop and carry it out. Many thanks as well to @azulsilva.bsky.social , @belalima-paiva.bsky.social and Eleonore for driving this work forward together. 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.

1/7 🧠 My journey into development begins with this work and question: how does the brain's spatial navigation system develop? We found that the neural networks for spatial navigation (tori and rings) are preconfigured and only later anchor gradually to the world with experience! 🧵

Happy belated publication of some of my PhD work! Building on our findings that grid field firing rate changes can cause hippocampal remapping and memory impairment, here we show that this effect has a fixed input-output relationship, and we can even predict how place cells will remap!

We had a lot of fun doing these experiments! Theta sweeps in MEC and internal direction signals in parasubiculum track moving objects during pursuit and reverse during backward movement. Simultaneously recorded HD cells in other areas remain locked to head direction across behaviors:

Really excited to share this Opinion piece we've been working on with fellow head-direction cell geeks @apeyrache.bsky.social @desdemonafricker.bsky.social and (bsky-less?) Andrea Burgalossi! While head-direction cells pop up in many cortical regions, we think that one of them is quite unique (1/8)

Stoked to see this paper finally out! It answers two big questions: where visual objects are encoded in the brain, and how head-direction cells get oriented using visual landmarks. Super fun collaboration with @mace-lab.bsky.social and Stuart Trenholm. www.science.org/doi/10.1126/...

Our new paper out now in Science explores how neural activity in the lateral entorhinal cortex (LEC) *drifts* over time - and *jumps* at key boundaries - to help organize events in memory. 🔗 www.science.org/doi/10.1126/... Here's a quick summary of what we found 🧵👇

Our experience of the world is a continuous stream of events that must be segmented and organized at multiple timescales. The neural mechanisms underlying this process remain unknown. In this work, we...

Excited to share the sequel to our 2022 paper! In this follow-up, we show that the stable head direction (HD) signals we reported in blind mice rely on stereo olfaction—that is, the comparison of odor info. between the two nostrils. Link: www.nature.com/articles/s41... 🧵highlights below

Check out Amy’s cool work on the octopus visual system! Amy + team describe novel receptors and map their distribution and function in the optical lobe. Turns out: Octos run different hardware to process visual input, but might have evolved similar circuit motives / logic to those in vertebrates!
