Are parts of the memory trace found in the ‘astroengram?’ thetransmitter.org/memory/are-par… What an enriching experience it is to discuss science with experts in the field! A fascinating discussion, and hopefully just the beginning of many more! @cncajal-csic.bsky.social @csic.es

Neuroscience hasn’t been able to investigate the role of astrocytes in memory because “all the tools we have to understand how the brain works are related to neurons." #neuroskyence By @davidbrz.bsky.social www.thetransmitter.org/memory/are-p...

Are parts of the memory trace found in the ‘astroengram?’

Neurons have long taken top billing in memory, but researchers are making the case for astrocytes.

The future of neuroscience meets at #CajalJunior26 🎉 On 18–19 June, predoctoral and postdoctoral researchers will share their latest findings alongside invited speakers including Javier Bernácer (Fundación Tatiana) and Carlos Gómez Guzmán (mpiforbi.bsky.social). 📅 Full programme below ⬇️

🔥 ¡Vuelven las #CajalJunior2026 al CNC! 🔥 📅 18–19 junio 🌍 Abierto a participantes externos 🧪 Charlas (10–15 min) + pósters 💡 Feedback, visibilidad + certificado 🎁 Y sí… premios y buen ambiente 🗓️ Inscripción hasta 15 mayo 👉 Link en bio

Hoy nos despedimos del #InstitutoCajal Han sido años de ciencia, aprendizaje y, sobre todo, de personas que han dado vida a cada pasillo, cada laboratorio y cada idea. Nos llevamos todo eso con nosotros. Vamos con ilusión hacia lo que viene con el #CentroDeNeurocienciasCajal 🫶

🧠 A new study led by our PI Marta Llinás published in Nature Communications shows that a specific #astrocyte ensemble drives memory deficits caused by adolescent #cannabis use in mice. 🔬 Reducing their overactivation prevents cognitive impairments. More info🔗https://shorturl.at/Mxih0

Our @natureportfolio.nature.com paper is featured in Editors’ Highlights “From brain to behaviour”‼️🆙 Thanks @MarsicanoLab @khakhlab @GrandesLab nature.com/collections/mj… @institutocajal.bsky.social @csicdivulga.bsky.social

🗞️Un estudio liderado por @navarrete-llinas.bsky.social @institutocajal.bsky.social muestra que los problemas de memoria y aprendizaje tras consumir #cannabis en adolescencia están modulados por #astrocitos, células tradicionalmente consideradas de apoyo de las neuronas 🔗https://buff.ly/N1Nt9ka

Células distintas de las neuronas medin la pérdida de memoria por cannabis. Un estudio en ratones muestra que el componente principal del cannabis sobreactiva a un grupo de astrocitos, que alteran la comunicación entre las regiones implicadas en el aprendizaje www.csic.es/es/actualida...

🧠Un estudio en ratones del @institutocajal.bsky.social describe el mecanismo celular que influye en la pérdida de memoria por consumo de cannabis 🔬Un grupo de astrocitos, células auxiliares de las neuronas, modula los déficits cognitivos asociados a su consumo en la adolescencia 👉 tiny.cc/nfwx001

🎉 Great news! Our paper is now published in @naturecomm We identify a specific astrocyte ensemble that mediates THC-induced cognitive impairments during adolescence Huge thanks to our collaborators @marsicanolab @khakhlab @grandeslab 🔗 rdcu.be/eY0Or @jsromero.bsky.social @crismonteagudo.bsky.social

The @navarrete-llinas.bsky.social lab is kicking off 2026 with even more new science! Our latest paper, led by the amazing @crismonteagudo.bsky.social, is out now in @natcomms.nature.com. 🧠 Astrocytes mediate cognitive impairments induced by THC 🌿 exposure during adolescence. 👇🏼

Getting a head start into the new year with the latest from the @navarrete-llinas.bsky.social lab out now in @natrevneuro.nature.com! Engrams are not composed solely of neurons: astrocytes also form coordinated ensembles that drive memory encoding and recall. 🧪 🧠 👇🏼

Y'all, I'm in this tweet! Won't do the where's Waldo thing, though (I'm too easy to spot). Jokes aside, thanks to Network Glia @gliameeting.bsky.social for the stipend to attend #GLIA2025!

Network Glia | European Glia Meeting@gliameeting.bsky.social · last yr.

#GLIA2025 is in full swing! We’re halfway through an exciting week full of energy, ideas, and exchange. Highlights so far: 🎓 Stipend Award Session 🧠 Poster Sessions 🤝 Welcome Reception Let’s keep the momentum going! #GliologistsTogether

This is today! I will be representing the @navarrete-llinas.bsky.social lab at #GLIA2025 talking about astrocyte ensembles in memory and behavior. Go check it out!

Navarrete Lab@navarrete-llinas.bsky.social · last yr.

Curious how astrocyte diversity rewires circuits & drives brain health/disease? Join our S24 symposium “Astrocyte Heterogeneity: Synapses → Behavior” at the XVII European Glia Meeting on Thu 10 Jul 2025! Proud #IBROSpeakerSupport awardee. See you there! #IBRO #IBROinEurope

Took a plane to Marseille this morning on my way to #GLIA2025. Landed in Nice instead because of a wildfire. At least I get to see some gorgeous views of the Côte Bleue from the train to Marseille. Could have been worse, I guess.

¡Nuestro stand en la feria #madridesciencia2025 está a tope! Estaremos hasta el sábado, ven a vernos y a aprender de neurociencia, microbiología, virología y astrobiología. Y si quieres momento instagram📸, nuestro arcoíris químico te vendrá genial 🌈🦠🧠🔬🧫🪨🧬

There are times when science and art collide. 🧪🎨 I once took these micrographs of astrocytes expressing CaMPARI-GFAP, a calcium indicator for taking snapshots of astrocytic activity. They reminded me of a firework display which just won first prize at SENC's #NeuroArt contest! 🎆 youtu.be/eyPI8r15db4

So I patched an astrocyte.

Impressive work by our very own @crismonteagudo.bsky.social on #astrocytes in THC-related impairments. 🧪🧠✨ Go show the preprint some love 👇🏼

Navarrete Lab@navarrete-llinas.bsky.social · last yr.

🚨New preprint alert!🚨 Excited to share our latest research led by @crismonteagudo.bsky.social on how accumbal #astrocyte ensembles modulate #THC impairments. Huge thanks to our collaborators: Nagore Puente, Pedro Grandes, Giovanni Marsicano, and Ana Covelo.🧪🐁🧠✨ www.researchsquare.com/article/rs-5...

Kicking off our Bluesky profile celebrating our newest publication in @natureneuro.bsky.social! Using our new tool AstroLight we demonstrate that a specific group of #astrocytes —an astrocyte ensemble— in the nucleus accumbens regulates cue-motivated behavior. Check it out!✨https://rdcu.be/d8qJi

We have a beautiful paper out in @natureneuro.bsky.social. Go check it out 👇🏼 #astrocytes

Nature Neuroscience@natneuro.nature.com · 2y ago

An #astrocytic ensemble that emerges in the nucleus accumbens upon activity during cue-motivated behaviors and is essential for modulating cue-reward associations 🧪🧪 www.nature.com/articles/s41...

Guess we're on Bluesky now.
