1391-Connectomic Basis of Neuromuscular Network Formation
This research utilizes connectomic analysis to map the development of mouse neuromuscular circuits from birth to adulthood. The study reveals a massive reduction in axonal branching, transforming neonatal poly-neuronal innervation into the simplified single-input connections found in adults. Researchers discovered a second form of synaptic refinement called interjunctional competition, where entire neuromuscular junctions are eliminated based on their physical distance and the synchrony of neural activity. Analysis shows that these connections are not random but follow a rank-ordered pattern…
