This research utilizes electron microscopy connectomics to establish the first comprehensive logic of how mitochondria are organized within neural circuits. By analyzing datasets from both fruit flies and mice, the authors discovered that mitochondrial size and shape are so specific to individual cell types that they can function as biological fingerprints to identify neurons. The study further reveals that mitochondria are positioned with micrometer precision along neurites, showing a strong preference for clustering near presynaptic sites and within regions of high neural activity. In the…
