Our paper is now online in eNeuro! This story is about how prolonged stressful experiences can affect the morphology of astrocytes and their relationship with the neurons. Here's to the starry cells of the brain!
In @SfNJournals #eNeuro by @SaptarnabN & Chattarji @NCBS_Bangalore, "#Stress Elicits Contrasting Effects on the Structure and Number of #Astrocytes in the #Amygdala versus #Hippocampus." bit.ly/2V5o99j #brain #CA3 #glia #neuron #neuroscience #plasticity #pyrimidal
Excited to present our work at SFN 2024. Thanks @Inscopix for the award and congratulations to all the winners.
🎉Exciting News! 🏆 Meet the 2024 @Inscopix Tech Award Winners: @MMostafizur_R, @SarahTThai, @PeyshyuanC Congrats to all awardees and lab mentors for their efforts! Don't miss #SfN24 as they showcase their groundbreaking work. Stay tuned this week to explore their abstracts.
Hands down @CortexGrc ‘24 was the best conference I’ve ever been part of. My inaugural GRS co-chair @julia_mitchh doing this along side me, @doc_becca and @DavidEMoorman for a diverse/inclusive GRC, but THE TRAINEES - the scientific future is dazzling because of our community🫶🧠
Back home supercharged after a wonderful week at the @CortexGrc and GRS. Thank you chairs @ShanskyLab @DavidEMoorman @drsilvershana @julia_mitchh for everything. And a big thanks to everyone for the amazing science, conversations and all the fun!
Also super excited to be elected alongside @Dr_Bediya as Chairs of the 2028 Frontal Cortex GRC 🤩🧠 We will place an emphasis on nurturing the next gen of cortex lovers, and to providing a platform for underrepresented cortex researchers across career stages and species 🐁🐒👩💼
Cummings lab had an amazing time at the Frontal Cortex GRS/GRC 🧠! We met so many brilliant scientists, learned a TON, and @cardosorodrigo2, @Bfitz_Sci, @HunterFranks17, and Zephyr Desa represented the lab with 4 exciting posters and 2 outstanding talks 📈🎤
🚨🚨Pre-print alert 🚨🚨 Led by @IbrahimOladepo: a computer-vision guided robotic commutator that can track mice & correct for animal heading direction changes. Simple to implement. Can be added to any existing commutator biorxiv.org/content/10.110…
NEW LAB PAPER ALERT! Ever asked… How are different BLA interneurons organized to support distinct microcircuit motifs and how does this relate to their in vivo activity patterns across fear conditioning and extinction… We got you covered 👇🏾 biorxiv.org/content/10.110…
🚨 COOL COSYNE WORKSHOP 🚨 yourbrainondrugswork.shop @achristensen56, @OttTorben, and I have organised a CoSyNe workshop about how psychoactive drugs modify neural and behavioural dynamics. Our superstar line-up includes @KathaSchmack, @kaymtye, @JonahPadawer @SamVesuna
New paper online! In 2018, we found a human brain signal that tracks real time fluctuations in mood/anxiety. Now Adam Jackson back-translates this biomarker to mice, dissects its circuit mechanisms, & tests its causal relationship to emotional state. 🧵1/6 authors.elsevier.com/sd/article/S08…
Excited to be a part of this recent study in @BiolP , along with @YannDromard and @AmelieBorie! We show that a pathway-specific neuropeptide loss hyperactivates somatostatin neurons in septum, impairing social fear extinction in Prader-Willi syndrome. sciencedirect.com/science/articl…
A 2023 essential!
I’m delighted to share this perspective that we put together with @papouinlab @ShiNungChing Here we propose a new framework on how to think about the roles of astrocytes in the brain, that we call contextual guidance. nature.com/articles/s4159…
An incredibly insightful study about how endocannabinoids helps us cope in stressful situations. Congratulations team!
In grad school we found that stress increased endocannabinoid levels in the amygdala… it only took 20 years to figure out how and what they do!! Final chapter of @veronikakondev thesis with special thanks to @yulonglilab @GrueterLabVandy! cell.com/cell-reports/f…
Very happy and proud that our paper is online in Neuron now. sciencedirect.com/science/articl… 🧵 includes a short summary of our findings:
🚨 New pre-print alert!🚨 Led by the brilliant, twitter-less post-doc James Hope. We built a 🤖 exoskeleton for 🐭🐁 so we can study their 🧠's as they go around navigating their world. An e.g., imaging 1000s of neurons in the cortex when mice walk an 8-maze. A 🧵
Brain-wide neural recordings in mice navigating physical spaces enabled by a cranial exoskeleton biorxiv.org/cgi/content/sh… #bioRxiv
It's finally out after peer-review. Post stress riluzole reverses delayed anxiogenesis and neuronal remodelling in the amygdala (and hippocampus). Grateful to Twitterless Zubin Rashid, Shona Chattarji and Siddhartha Dutta for shaping this incredible study. academic.oup.com/pnasnexus/adva…
