New cell-type for #FluorescenceFriday: astrocytes in the cerebral cortex

Which track do I choose: On #FluorescenceFriday, a pair of newly formed oligodendrocytes encounter a field of neuronal axons. Later in development, they will wrap around and insulate subset of these axons

The hippocampus is one of the most studied brain areas because of its major role in fundamental brain functions including learning, memory, and spatial navigation. In a new #ScienceReview, researchers focus on the role of overlooked areas and circuits within the hippocampus. https://scim.ag/3VKRbMM

Delighted to share this work on intracortical arbor development and selective synaptogenesis by corticothalamic neurons. This was a really fun collaboration with Alan and the Brown lab during my PhD.

The Wu Lab at @JohnsHopkins is looking for a new postdoc fellow to study sleep and/or circadian-related behaviors in mice. If you're interested in, please contact us. www.markwulab.net

#JNeurosci: @srirams433.bsky.social‬ Guzman-Clavel et al. uncover roles for Mef2c in cortical development: regulation of laminar subtype specification during embryogenesis & axon targeting in postnatal callosal neurons. @oneneuroinitiative.bsky.social https://doi.org/10.1523/JNEUROSCI.0201-25.2025

Stanford research by Dr Barres changed our understanding of myelin—once seen as static insulation, now linked to learning & memory.

Celebratory #FluorescenceFriday this week, with the JNeurosci cover featuring an image from our article on how Mef2c controls intracortical projection targeting

The winner of OneNeuro's April #FotoFriday #FluorescenceFriday contest was submitted by Luis Guzman-Clavel at the Alex Kolodkin Lab. For more information, see pubmed.ncbi.nlm.nih.gov/40228894/ View the complete gallery of OneNeuro BRAINART images here: www.oneneurojhu.org/art/

Our latest manuscript (7 years in the works) tackles the question of how diurnal ground squirrels evolved a cone-dominant retina, in contrast to the ancestral rod-dominant retina retained by virtually all other mammals./1 www.biorxiv.org/content/10.1...

Our field has lost an amazing scientist, mentor, and old friend. Benny, along with Mike Hoffman, had a brilliant idea in the early 1980s. The first oncogenes were being cloned and they realized if we wanted to understand their roles in cancer, we needed to understand their normal function 1/n 🧪

I am proud to share that our work of 4+ years has finally been published. We wondered if there are distinct behaviors that mark sleep in 🪰, where sleep has been defined as prolonged immobility. 🔗 www.science.org/doi/10.1126/...

Bittersweet #FluorescenceFriday saying goodbye to the Kolodkin lab with one last image, this time from the retinal side side of the lab. Here's a collection of retinorecipient targets in the mouse brain. How many of them can you name?

We're organizing the 4th iDISCO / TRISCO workshop at @rockefelleruniv.bsky.social in NYC! April 14-19 - FREE - registration to [email protected]. Deadline: March 1st. We'll talk about brain mapping of cells, genes, axons, vasculature, light sheet microscopy, tissue clearing.

'From thought to action'... axons from the sensory cortex (green) arrive in the motor region to synapse with target neurons (yellow). Can't wait to get back to more imaging after weeks of thesis writing #FluorescenceFriday

Happy to share our pre-print, “ Mef2c controls postnatal callosal axon targeting by regulating sensitivity to Ephrin Repulsion”. We found that the topography of interhemispheric connectivity in the cerebral cortex is disrupted upon Mef2c deletion.(1/n)
