Hello, everyone! Please enjoy one of my favorite micrographs while I finally get set up over here. Vasculature (magenta, perfused lectin), GFAP (cyan), and cx43 (green) in a conditional astrocyte cx43 knockout mouse, demonstrating that cx43 is lost from astrocytes but not pericytes after tamoxifen.

I wrote a recent survey about deep reinforcement learning. The paper is a compact guide to understand some of the key concepts in reinforcement learning. Link: arxiv.org/pdf/2401.023... #ReinforcementLearning #ICLR2025 #ACL2025 #NAACL2025 #NeurIPS2024 #ICML2025 #DeepRL #DeepReinforcementLearning

Hello! I'm a neuroscientist working on astrocytes and brain states! Happy to be here and interested to see what it's like. Here's a video of astrocyte and neuron activity we recorded to start things off. #introduction #neuroscience #datascience #astrocytes

I might as well post my favorite animation I've made here. This is an EM reconstructed astrocyte surrounding a single neuron in mouse visual cortex. Meshes from the MICrONS dataset. #neuroscience #astrocytes

I am usually not fan of atlases… but this one is actually useful, as it demonstrates the value of protein-level measurements to identify functional cell states. #Brain #Development www.nature.com/articles/s41...

🪰My personal favorite “understudied” anatomical structure of the fruit fly #drosophila is the “proventriculus” (AKA the cardia), where the foregut meets the midgut. Here are #confocal images of various Gal4 lines, green. Blue is DAPI (DNA), magenta is phalloidin (f-actin).

Starting the week strong! Cheering myself up for the next challenges with 15 min of axonal growth cone dynamic madness. F-actin (cyan) and membrane (magenta) show their dance. One image taken every 10 s.🧠🔬 #MicroscopyMonday #LiveImaging #Neuroscience #Microscopy

This may be the most important scientific finding of the year and it is largely unknown. The AMOC far more sensitive to ocean warming than was expected. When I read that paper by Rahmstorf, my jaw dropped. Climate change is a slow motion disaster, but this will be an exception. t.co/89PA0HbRQR

doi.org/10.1017/S174... I knew Lin and Vincent but never put it together that their work on the commons and polycentricity was deeply influenced by cybernetics and Ashby's ideas about requisite variety.

First post! Does the success of deep neural networks in creating AI systems mean Bayesian models are no longer relevant? Our new paper argues the opposite: these approaches are complementary, creating new opportunities to use Bayes to understand intelligent machines arxiv.org/abs/2311.10206
