Link doubling reduced some remote voltage transfers in passive models of two partial adult worm maps

We tested whether a stronger electrical link can lower steady voltage transfer between two other cells. We used 180 common neurons from two partial adult C. elegans maps and a passive circuit with equal positive membrane leak. At the primary leak, doubling one recorded link lowered transfer by at least 1 percent in 3834 of 244660 eligible remote cases in adult 7 and 5709 of 307943 cases in adult 8. The shares were 1.57 and 1.85 percent. Endpoint transfer rose for every doubled link. At tenfold leak, no eligible remote case changed by at least 1 percent. A standard inverse formula gives an exact sign test for any finite single-link gain. An original four-cell example and separate full matrix inverses support the calculation. Incomplete electrical annotation, assumed conductance and leak, two selected maps and no matched activity prevent a claim about live-animal responses or reliable representations. Original code, aggregate results, source hashes and separate external-data retrieval steps support reproduction.
