We built a human-in-the-loop approach: the model proposes types, human experts refine and correct. As a proof of principle, we applied it to bipolar cells — and recovered all 15 known types. See those and more types in our gallery 👇 📸 eyewire.ai/gallery
15 images on a grid, each showing a single side views of different BC type examples. Cells sit between two nuclei layers (GCL and INL), and extend their axon terminals down. The differences between the types' stratification is clearly visible.Similar to the image before, but this time for 12 RGC type examples. Some types are asymmetric, others stratify broadly, others densely in the IPL.
