Glutamate indicators with increased sensitivity and tailored deactivation rates 🧪

On the left, the image shows a schematic of a fly head, ring neurons and EPG neurons together with some calcium imaging frames. On the right is a photo of a fly on a ball in virtual reality and another schematic of a VR system.

📢 Join us, the Haberkern lab, @uni-wuerzburg.de for a postdoc studying neural circuit mechanisms of navigation. You’ll spearheading neurophysiology experiments on our brand new 2P!

Learning how to ignore hunger does not sound like a great evolutionary strategy. They might need admin privileges to control those.

The hustle to crack the genetic code between Nirenberg and Ochoa was a pretty spicy one too! Or so I hear.

highly processed calcium imaging >>> highly processed foods

congrats! one of the most exciting things I remember from SLB. glad to see it out!

🚨iGluSnFR4 is finally out!🚨🧪

We present iGluSnFR4f and 4s, a novel pair of genetically-encoded glutamate indicators designed for high-fidelity imaging of synaptic activity in the living brain. ⬇️

Happy new year sky fam

Can't get the pdf to load :( hope it's just a me problem

Happy Thursday. Bird up

off target

Maximal support but only self generated starter packs count go.bsky.app/3vKYJLF

Rainy day bird

and the campus is on the beach

these are very fun, thanks!

Microscopy photo showing some cell types in the brain, including neurons in blue, astrocytes in gold and microglia in purple. Piece of the frontal cortex (Brodmann area 46), rhesus macaque.

Just a piece of cortex I saw under the microscope today 🤓🔬
Cell types: neurons 🔵, astrocytes 🟡, microglia 🟣. Observe how astrocytes are covering two long blood vessels, crossing all the gray matter and almost reaching white matter. The brain is so pretty!

Still here

'can't spell behavior without u' sounds like a 10/10 pickup line

New day new bird

This place sort of feels like the science Twitter I used to like. Maybe even better? Fingers crossed.

Wish I had a fresh preprint to share, but here's the next best thing:
a fresh osprey with some blue sky background.

never gets old
