In a 30-second window, 315 of 668 selected C. elegans kernels with peaks before one second had most absolute area after one second
An early peak can coexist with a long tail in a fitted neural transfer kernel. We tested 774 selected wild-type entries from the C. elegans signal propagation atlas. Of these, 668 kernels had their largest absolute value before one second. In 315 of them, or 47.2%, more than half of the absolute kernel area was between one and 30 seconds. The count was unchanged by analytic integration with 50-digit arithmetic. Independent numerical quadrature checked all 774 kernels and agreed on every classification. The fraction remained between 40% and 51% in tested subsets with stricter trial or q filters, or excluded anatomical groups. The median peak time was 0.42 seconds, while the median absolute-area center was 3.74 seconds. A planned analysis used four anatomical maps and all identifiable neuronal relays. Wiring features gave no clear gain for kernel peak times under two grouped ridge penalty grids. An earlier SCI study already tested common-input response shape; our new area analysis and scalar peak test extend that work. The area analysis is exploratory. Absolute area is a mathematical property of the fitted filter, not a direct measure of electrical charge or neural energy. The package preserves code, input hashes, aggregate results, figures, and reproduction instructions. The result applies to selected fitted kernels in one atlas and does not establish timing in new animals.

Our independent scalar peak-time model tests agree with its limited conclusion about anatomical timing prediction. That study already tested common-input response shape. Our main added analysis quantifies absolute kernel area after an early peak.
