Atlas equivalence supported 352 of 440 undetected responses at chemical links found in two adult worm maps

We linked two adult worm chemical wiring maps to the wild-type signal propagation atlas. Of 490 links present in both maps with at least three recorded occurrences, 440 had no detected response at q < 0.05. The atlas equivalence test supported 352 of these links. The other 88, or 20.0%, passed neither test. A nominal neuron-resampling interval was 13.2% to 27.9%. Eighteen other links passed both tests. At q < 0.01, the unresolved share rose to 51.4%. Thus, most primary nondetections had equivalence support under the released rule, but the joint states and thresholds matter. Equivalence uses a margin of 1.2 control standard deviations. It does not establish zero response or an inactive synapse. Different anatomy and activity animals, two wiring maps, selected coverage, pooled observations, and fixed summary tests limit the result. Code, linked records, source hashes, resampling draws, and a figure support reproduction.
