Whole-Brain Connectomics

# Whole-Brain Connectomics **Entity class:** Concept or analytic term **Collection:** [[collections/Neurotech|Neurotech]] **Type:** Connectomics scope concept **Primary sources:** [[articles/2026 Annual Report on Brain-Computer Interfaces|2026 Annual Report on Brain-Computer Interfaces]]; [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]] ## Definition **Whole-brain connectomics** seeks a connectivity map spanning an entire nervous system or brain under a specified inclusion threshold. ## Relationships - [[wiki/FlyWire|FlyWire]] provides adult insect whole-brain structural coverage. - [[wiki/ZAPBench|ZAPBench]] provides whole-brain vertebrate activity while aligned reconstruction remains a separate milestone. - The [[wiki/Aedes aegypti|Aedes aegypti]] project extends the approach to a disease-vector species. - Whole-brain coverage leaves synaptic completeness, functional state, or identity sufficiency unresolved.  This entry's documented connections are expressed in its definition and related-work routes, with provenance retained in the source-linked material.  ## Related Work in the Corpus  - In [[articles/2026 Annual Report on Brain-Computer Interfaces|2026 Annual Report on Brain-Computer Interfaces]], **FlyWire: Whole-Brain Completeness at Insect Scale** provides the narrative context for **Whole-Brain Connectomics**: In May 2025, Jefferis and Elizabeth Marin secured a Wellcome Discovery Award to produce 'A whole-brain connectome of the female Aedes aegypti mosquito,' in collaboration with Wei-Chung Allen Lee (Harvard Medical School) and Meg… - In [[articles/2026 Annual Report on Brain-Computer Interfaces|2026 Annual Report on Brain-Computer Interfaces]], **MICrONS: Function-Structure Registration at Mammalian Scale** provides the narrative context for **Whole-Brain Connectomics**: As David Markowitz (IARPA Program Manager) stated: 'IARPA's moonshot investment in the MICrONS program has shattered previous technological limitations, creating the first platform to study the relationship between neural…  ## Research Inference Attractors  These are secondary semantic placements for the inference attractor network.

Human connectomics is underway at millimeter scale today. - **Canonical cluster:** [[wiki/Connectomics|Connectomics]] - **INF-0111 — Strongly indicated.** At current electron-microscopy economics a whole mouse brain implies tens of billions of dollars; at a 100× reduction it becomes a large-instrument-scale project comparable to a telescope. That crossing converts the mouse connectome from a thought experiment into a fundable program. - **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-0123 — Analytic.** A human brain holds on the order of a thousand times the neurons of a mouse, so a mouse-scale success does not imply a human one without another cost reduction of similar magnitude. Naming the required factor explicitly is what turns the roadmap into an engineering schedule. - **Canonical cluster:** [[wiki/Connectomics|Connectomics]] - **INF-0124 — Unresolved.** Human connectomics depends on tissue quality achievable within realistic post-mortem intervals, and that quality ceiling has not been characterized at whole-brain scale. Resolution requires a coordinated perfusion protocol study, which is an institutional rather than technical undertaking. - **Canonical cluster:** [[wiki/Connectomics|Connectomics]] - **INF-0127 — Strongly indicated.** Benchmarking whole-brain activity prediction in larval zebrafish turns emulation from an argument into a leaderboard. Once a capability has a benchmark, it acquires a measurable improvement rate, and measurable improvement rates end debates about feasibility. - **Canonical cluster:** [[wiki/Whole-Brain Emulation|Whole-Brain Emulation]] - **INF-0141 — Analytic.** The field is climbing an explicit ladder — worm, fly, zebrafish, mouse, primate, human — and each rung is a funded program with published milestones. Reading the ladder as a schedule rather than a metaphor produces a defensible estimate of when human-scale attempts begin. - **Canonical cluster:** [[wiki/Whole-Brain Emulation|Whole-Brain Emulation]] - **INF-0143 — Plausible.** Replacing one circuit with a simulated equivalent while the rest of the brain runs biologically is the incremental path, and hippocampal prosthesis work has already done it in rudimentary form. Gradual replacement sidesteps the discontinuity problem that whole-brain transfer raises. - **Canonical cluster:** [[wiki/Whole-Brain Emulation|Whole-Brain Emulation]] - **INF-0147 — Analytic.** Roadmaps written in the 2000s specified resolution, throughput, and compute requirements that can now be checked against delivered capability. Auditing those predictions against 2026 reality is the most rigorous available method for calibrating the remaining timeline. - **Canonical cluster:** [[wiki/Whole-Brain Emulation|Whole-Brain Emulation]]  ## Simple Reminders, Quotations, and Thoughts  > "We aim at reading the first complex memory from a vertebrate brain to deepen our understanding of how neural circuits encode, store, and retrieve information at the level of synaptic connectivity." > **— Kornfeld Lab**, *institutional research mission* [[reminders/Connectomics/Reading the First Complex Memory from a Vertebrate Brain by Kornfeld Lab|Reading the First Complex Memory from a Vertebrate Brain by Kornfeld Lab]] > "The brain is an electrical device.
