🟠 🔬 There is a new sensitive orange #calcium indicator: #OCaMP
📄 https://www.nature.com/articles/s41467-026-74553-4
Highlights:
⚡ Detects single #ActionPotentials #InVivo
🔬 Optimized for 1030 nm #imaging
📸 Highly #photostable, minimal photoswitching
🌈 #Multiplex with green biosensors -
Are action potentials in vertebrate muscle essential for contraction? This study of #zebrafish lacking #SodiumChannel NaV1.4 reveals that NaVs are dispensable for #muscle contraction, so the need for muscle #ActionPotentials can vary between vertebrates @PLOSBiology https://plos.io/42EXQwx

Why is neuronal repolarization during #ActionPotentials so uniform despite ~10x range in axonal diameter? Study shows that higher K+ currents in smaller #axons compensate for biophys constraints, resulting in size-independent trigger signals #PLOSBiology https://plos.io/3ZzJvzE
