NAC coding for distance to goal is dependant on VTA's dopamine, but not HPC or PFC activity. Really cool stuff from the Ito group!

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.

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

My main postdoc work is now published: www.nature.com/articles/s41...! We (myself, Isabel Low, Frances Cho, and @lgiocomo.bsky.social) discovered task-relevant remote representations in entorhinal cortex independent of CA1. #paperthread below! 1/13

🔔PREPRINT: Sleep ripples drive single-neuron reactivation for human memory consolidation
1/9: How does sleep support human memory consolidation? To test this, we recorded hundreds of neurons in the human medial temporal lobe (MTL) across learning, wakefulness, and sleep.

Astounding work!
I don't know much about subiculum but do we know, or can you speculate on the interaction between HPC CA1 Sharp wave ripples and these plateau you describe? We know SWR occur more at reward, could they be driving these "low" plateaus?

🚀 New preprint from the lab! Our first foray into the subiculum uses in vivo whole-cell recordings to show that dendritic plateaus are a prominent, learning-dependent signaling mode of subicular neurons. Feedback is welcome!

I’m pleased to share our new paper, “Hippocampal ripple diversity organizes neuronal reactivation dynamics in the offline brain”, out in @cp-neuron.bsky.social !

With @vitorlds.bsky.social and David Dupret, we show that diversity in ripple current profiles shapes reactivation dynamics

Thanks, that explains a lot of things!

Could it be that photometry averages two different populations, one that is responding to reward onset, one that increase at CS+ time? (Somehow remind me of this paper pmc.ncbi.nlm.nih.gov/articles/PMC...) Or did I just misread the old papers?

Very cool data! Congrats! I have so many questions!
First one that pop to my mind: I'm suprised to see that DA and GABA neurons keep firing at the reward time, even during 'late' phase. My understanding of classical Schultz results were that the response to reward faded away with learning?

Very excited to share this major update to our paper delineating VTA GABA neuron encoding of valence and decision conflict. Studies led by the amazing @margestelzner.bsky.social. We leaned in here, taking the opportunity to add a lot of cool new data. www.biorxiv.org/content/10.1...

We show how CRH in the thalamic reticular nucleus modulates NREM sleep, helping to understand how stress impacts sleep

I'd be happy to help!
