Side totals recover 78 of 83 bilateral assignments between two adult worm maps

We tested whether chemical connection profiles distinguish the left and right members of known neuron pairs across adult C. elegans maps D7 and D8. Input and output profiles to named partners recovered 79 of 83 pair assignments. Hiding the side of each bilateral partner reduced the count to 40. A follow-up control using only total inputs and outputs to left, right and unpaired partners recovered 78. Query neurons and their mutual links were excluded from features. Inputs alone recovered 80 pairs, and direction-erased counts recovered 81. High matching accuracy in this task therefore does not require detailed partner identity. These are results for two fixed partial brains with known partner labels. They do not establish reliable neural activity, arbitrary cell identification, or population accuracy. Code, matrices, pair scores, anchor subset draws, source hashes and independent checks support reproduction.
