Meet Eyewire II: a new connectomic resource for the mouse retina. ~1 mm² of retina at nanometer resolution, with synapses and circuits of ca. 100,000 neurons, plus visual responses from the ~400 neurons shown in the video! Preprint: doi.org/10.64898/202... Data: eyewire.ai 🧠📈 🧠💻🧪 #VisionScience

Spinal motor neurons in dazzling detail. ✨🧠 Each green dot is a spinal motor neuron - crucial but rare cells making up just 1% of spinal cord neurons. In diseases like #ALS, they are selectively damaged, making them of special interest to neuroscientists. 🔗 https://bit.ly/4anj19z #SciShots
