Acute or selective nNOS inhibition preserved the spatiotemporal features of Stage III retinal waves but significantly changed network topology, increasing network degree and density. Molecular profiling showed that nNOS blockade lowered the expression of chemical (SYN, SYP) and electrical (Cx36, Cx45) synaptic genes, disrupted their laminar distribution in vivo, and increased neurite length in primary retinal cultures without altering branching complexity. By combining ultrasensitive NO detection, large-scale electrophysiology, and mathematical network analysis, our results identify NO as a key regulator of circuit refinement that operates largely independently of the spatiotemporal dynamics of retinal waves during development.
