Observed site groups gave cuts within fixed-count shuffle ranges in two adult worm models
We tested directed route survival in two public adult C. elegans brain maps. We used 162 fixed neurons and treated a chemical synaptic site with several targets as one failure unit. The mean minimum site cuts were 11.15 and 11.67. The corresponding independent-contact cuts were 13.78 and 14.83. We compared site grouping with source-specific shuffles that keep all pair counts and site sizes. For 256 fixed pairs, observed mean site cuts were within the central 95 percent shuffle range in both maps. Lower-tail ranks were 0.095 and 0.647. Thus this test gave no clear added grouping effect. This model does not measure release, trial reliability or activity. Partial brain coverage, missing electrical links, shared cells and two animals limit biological use. Code, site tables, all pair cuts, shuffle draws and independent checks support reproduction.
