# Nanometer-Resolution Imaging **Collection:** [[collections/Neurotech|Neurotech]] **Type:** Imaging-resolution concept **Primary source:** [[articles/2026 Annual Report on Brain-Computer Interfaces|2026 Annual Report on Brain-Computer Interfaces]] ## Definition **Nanometer-resolution imaging** resolves structures at billionths-of-a-meter scale, enabling synapses, fine neurites, and cellular boundaries to be distinguished in connectomic tissue volumes. ## Relationships - [[wiki/Electron Microscopy|Electron microscopy]] is the principal modality in the FlyWire source passage. - The images become input to [[wiki/Machine Learning Segmentation|machine-learning segmentation]] and human [[wiki/Connectome Proofreading|connectome proofreading]]. - Resolution is one attribute; volume coverage, contrast, tissue preparation, and reconstruction accuracy remain separate.
