#microns — Public Fediverse posts

I first got excited about this ~8y ago when I started seeing a pattern in #microns and other datasets at bossdb.org

Usually neuron cell bodies are spread out... But every so often, you get what I call "cuddle buddies". wtf?

Scientists have created the most detailed wiring diagram of the brain ever, thanks to IARPA’s MICrONS program. They mapped over 200,000 cells and 500 million synapses in a mouse’s visual cortex, linking structure and function at an unprecedented scale. This breakthrough could revolutionize our understanding of cognition, consciousness, and brain disorders.

Wie funktioniert das #Gehirn? Mit dem bisher größten Schaltplan und der größten Funktionskarte eines Säugetiergehirns ist ein weltweites Team mit Beteiligung unserer Uni der Antwort näher gekommen.

Das Team kombinierte Live-Aufnahmen von Gehirnbildern mit hochauflösender #Mikroskopie und #KI, um nie zuvor gesehene Einblicke in die Funktion und Organisation des Sehsystems des Gehirns zu gewinnen: https://www.uni-goettingen.de/de/3240.html?id=7776

Scientists map the half-billion connections that allow mice to see https://www.princeton.edu/news/2025/04/09/first-time-scientists-map-half-billion-connections-allow-mice-see #MICrONS project

The MICrONS Project https://www.nature.com/immersive/d42859-025-00001-w/index.html "An unprecedented dataset of high resolution anatomical images of individual cells in mouse visual cortex, mapped on to their responses. This integrated view of function and structure lays a foundation for discovering the computational bases of cortical circuits."

They said it couldn't be done ... but neuroscientists have successfully mapped all the cells in a cubic millimeter of #brain tissue, and have traced how the neurons fire. Find out more about the $100 million #MICrONS project and the role that Seattle's #AllenInstitute is playing. https://www.geekwire.com/2025/brain-microns-wiring-diagram-connections/ #Science #Neuroscience

Results: In this study of the #MICrONS 🐭👁️-cortex 3D #ElectronMicroscopy dataset, I show how the shape of #Contractile #MuralCells transition from #PenetratingArteriole to #PrecapillarySphincter to #Capillaries. Vascular lumen = blue, mural cells = various colors (5/15)

When I was a kid, my father bought one of those "Great Books" collections. One of them was "In Praise of Folly" with illustrations by Hendrik Willem Van Loon, a popular children's illustrator. I loved those quirky scratchy sketches and copied many of them. I guess I have incorporated that style into my adult life. Still quirky and scratchy.
These are sketches of people in a Zoom class I attend.
