Collection route: [[collections/Neurotech|Neurotech]]. - **INF-0112 — Established.** Losing or damaging ultra-thin sections fragments a dataset into discontinuous chunks, and no group has traced neurons through even a millimeter of sliced tissue in all three axes. Mechanical handling, not imaging, is the unglamorous constraint on long-range connectivity. - **Canonical cluster:** [[wiki/Connectomics|Connectomics]] - **INF-0113 — Analytic.** Local circuits can be reconstructed from small volumes, but identity-relevant computation depends on long-range projections that cross the whole brain. A connectome that omits long-range structure describes a component, not a mind, which makes volume continuity the key acquisition property. - **Canonical cluster:** [[wiki/Connectomics|Connectomics]] - **INF-0117 — Unresolved.** Whether synaptic strength can be inferred reliably from morphology alone is the open question that determines if a static connectome is sufficient for function. Resolution comes from paired physiology-and-ultrastructure datasets, which MICrONS-class experiments are designed to produce. - **Canonical cluster:** [[wiki/Connectomics|Connectomics]] - **INF-0118 — Analytic.** Connectomes record wiring but not the diffuse neuromodulatory context that sets gain across the whole network. Recovering that context requires molecular measurement alongside structure, which is precisely what molecular-annotation methods add, closing a gap most emulation critiques assume is permanent. - **Canonical cluster:** [[wiki/Connectomics|Connectomics]] <!-- END DEEP INFERENCE ATTRACTORS 2026-09-11 -->
