Matched windows in 23 C. elegans worms showed no clear increase after light in the electrical count term for response correlation

We tested whether the relation between electrical anatomy and shared trial changes increases after single-neuron stimulation. We used fixed DANDI data and a reference C. elegans connectome. Three eight-second windows had equal twelve-second spacing. We centered target changes within repeated-source groups. The main panel had 4,209 animal and target-pair rows from 23 worms. A weighted linear model controlled animal, target identity and chemical wiring. The fitted correlation contrast from zero to two electrical sections was +0.157 before light and +0.142 after light. The direct after-minus-before contrast was -0.015, with a 95% range of -0.114 to +0.067 from 4,000 refitted animal bootstrap samples. All specified difference ranges included zero. The data support an electrical-count association already present before the current pulse. They give no clear evidence that this association increases after the pulse. They do not establish equal effects or a direct junction mechanism. An added algebra check shows why a positive baseline-adjusted coefficient need not imply an increase. The package preserves code, raw window means, fixed source keys, source URLs and hashes, all fits and bootstrap draws, figures, and repeat steps. No new neural measurements were collected.
