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!

Honored to have worked on this fun study which puts forth a cautionary tale on a rather colorful cannabinoid consumer product landscape. Deeply enjoyed the journey from figuring out CeA GRIN lens implants to finding dose dependent effect of cannabinoids on fear.

Had a fantastic first Winter Brain! The people, the science, the mountains!!! Thanks for organizing the panel @veronikakondev
Another winter brain in the books! Thanks to Laura & Julia for organizing a great panel & @SaptarnabN Miguel & Anthony for loving endocannabinoids with me :D

New preprint alert!🚨
Mice on high-fat diet since adolescence show poor memory and altered in vivo spine dynamics - both rescued with time-restricted feeding for 4 weeks!
Grateful to my postdoc mentor Freddy and our wonderful collaborators! 1/2

It's finally out in @jclinicalinvest. We study the role of 2AG depletion in fear generalization and associated prefrontal neuronal activity. Congrats to the X-cluded Luis E Rosas-Vidal, @SachinPatelLab and everyone on the team! jci.org/articles/view/179881…
Excited to share this preprint and super happy to have worked alongside twitterless Luis-E Rosas Vidal and @SachinPatelLab for this study. Shout out to all the incredible contributors! @MayoOnTheBrain @

✨ Announcing a new glutamate indicator - iGluSnFR4! ✨
Launched as a pair, iGLuSnFR4s and iGluSnFR4f have high-sensitivity and fast activation/deactivation for recording synapses.
More on the indicators and what they are already revealing: biorxiv.org/content/10.1101/…

Our new study from
@DulacLab led by the amazing @dingliuabc. We identify the neural circuit that responds to social isolation consisting two distinct neuronal populations. We also demonstrate that lack of touch leads to emergence of social need.

Ever wondered how cannabis consumption made you anxious/panic? Check out this preprint that sheds light on it! Thoroughly enjoyed working through this rollercoaster of a project!! Thanks @SachinPatelLab , @farhana_yasmn
and Luis Rosas for the opportunity to work on this.
If you’re interested in understanding how cannabis can increase anxiety and cause panic reactions in some people, this paper might help👇🏾👇🏾👇🏾👇🏾

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🫶🧠

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 📈🎤

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/10.1101/…
