My lab is recruiting a postdoctoral researcher! Interested in astrocyte transcriptional regulation and addiction? We study how astrocytic transcriptional, epigenetic, and chromatin regulation contributes to substance abuse disorders. DM or email me! www.l-holt-lab.com

Move over, GLM-HMM—there’s a new hidden Markov model in town. In our new preprint, we introduce the DDM-HMM: a model that jointly infers latent decision states from reaction times and choices. Using 24-hour behavioral data from rats, we found that evidence accumulation changes with time of day!

Astrocytes do so much more than any of us thought - they even communicate among specific brain regions across hemispheres! The journey to this paper spanned nearly a decade, but I'm most excited to see what everyone else does with the tools we've built. There's so much for all of us to explore!

Astrocytes connect specific brain regions through plastic networks - Nature

Communication between distant brain regions is mediated by plastic networks of gap junction-coupled astrocytes.

Excited to share our new preprint! We explore the link between the locus coeruleus (LC) and arousal for astrocytes, pyramidal cells, interneurons in the hippocampus. A fantastic collaboration with @sianduss.bsky.social @bohaceklab.bsky.social, and many others: www.biorxiv.org/content/10.6... 1/5

Thrilled to wrap up the year and my postdoc work in the Nester lab with this publication 🥳! We show that astrocytic CREB regulates astrocyte calcium and D1-MSN activity to drive behavioral response to cocaine. pubmed.ncbi.nlm.nih.gov/41406210/

Just out in Nature! “The astrocytic ensemble acts as a multiday trace to stabilize memory.” We identified astrocytic ensembles that link experiences across days to stabilize memory nature.com/articles/s41.... New astrocyte tools are openly available at Addgene: addgene.org/Jun_Nagai/. 1/8

90% of neuroscience papers are one of: 1. it turns out what we thought was generally true was actually just a special case 2. the thing we think is true contains smaller things that we can measure 3. what we thought was true is still true, but now with lasers pew pew

This is why science funding matters. We uncovered a hidden signaling system in the brain—one that responds to maternal environment, even to drugs like LSD during pregnancy. It took 5 years, a brilliant team, and public funding to get here. Out today in @NatureNeuro: 🧵👇

Sharing a new paper from the lab. This paper, led by Sangyoon Ko, represents a merging of two longstanding research themes in the lab-- adult neurogenesis and systems consolidation. rdcu.be/el18q A short thread follows for those interested. 1/n

Systems consolidation reorganizes hippocampal engram circuitry

Shared some of my recent experiences and thoughts with @callimcflurry.bsky.social of @thetransmitter.bsky.social. In these chaotic times, it’s important that there’s an ability for voices to be heard. I’m very thankful to Calli and The Transmitter for the opportunity.
