Color and polarization provide complementary information about the world are detected by specialized photoreceptors. However, downstream neural circuits that process these distinct modalities incompletely understood in any animal. Using electron microscopy, we have systematically reconstructed synaptic targets of photoreceptors to detect color skylight Drosophila, used light microscopy confirm many our findings. We identified known novel selective for different wavelengths or polarized...
Summary Many animals rely on vision to navigate through their environment. The pattern of changes in the visual scene induced by self-motion is optic flow 1 , which first estimated local patches directionally selective (DS) neurons 2–4 . But how should arrays DS neurons, each responsive motion a preferred direction at specific retinal position, be organized support robust decoding downstream circuits? Understanding this global organization challenging because it requires mapping fine,...
Abstract Flying insects exhibit remarkable navigational abilities controlled by their compact nervous systems. Optic flow , the pattern of changes in visual scene induced locomotion, is a crucial sensory cue for robust self-motion estimation, especially during rapid flight. Neurons that respond to specific, large-field optic patterns have been studied decades, primarily large flies, such as houseflies, blowflies, and hover flies. The best-known optic-flow sensitive neurons are tangential...

In this protocol we describe the voxel-based classification of organelles and cellular substructures in volume electron microscopy data used to train deep learning networks for automated segmentation. This is centered around using Amira software ‘painting’ details how CellMap Project Team has defined [up to] 37 semantic segmentation tasks. was described Heinrich et al, Nature (2021).
