Integrated Guide · Chapter 6

What to do now — guidance by position.

The current status in Chapter 3 and the dependency structure in Chapter 4 make it possible to identify the buttons that, when pushed, actually move the whole field. This chapter states the field-wide priorities first, then gives concrete suggestions for researchers, students, funders and individuals. It ends with something equally important: what not to do.

6.1 Priorities

Five buttons that move the whole field.

#PriorityWhy it is rate-limitingWho is working on it
P1Fully automated proofreading — cutting AI segmentation error rates by orders of magnitudeThe mouse connectome (M3) essentially depends on it. Straight extrapolation of manual proofreading gives thousands of person-yearsGoogle, Princeton and E11 among others. The area with the highest demand for people1
P2The science of inferring dynamics from structure — recovering synaptic weights and modulatory state from EM morphologyChapter 2's "greatest scientific uncertainty". A finished map will not run without itMICrONS validation work and digital-twin approaches have reached the entrance2
P3Validation benchmarks — extending the ZAPBench pattern to nematode, fly and mouseWithout a yardstick for "it worked", neither progress nor investment decisions are possibleZAPBench is the first instance. Standardised behaviour and perturbation batteries are a blank space3
P4Scientific validation of preservation — quantifying ASC quality in human post-mortem brains; demonstrating preserve-then-read-outThe only axis relevant to people alive now. Unvalidated adoption is an ethical risk; validation removes the time constraintThe Nectome preprint and BPF evaluations exist, but independent verification and standards are lacking45
P5Getting ahead on ethics and governance — consent design, emulation welfare, brain-data protectionReactive handling risks halting research; proactive work turns social trust into an accelerantAcademic proposals exist (Sandberg 2014, Metzinger 2021) but institutionalisation is at zero67

6.2 For Researchers

For researchers and engineers: open problems by axis.

AxisProblems worth working on
1. MappingSelf-correcting segmentation, including barcode-assisted approaches such as PRISM; integrating molecular annotation of transmitters and receptors at synapses; hybrid pipelines combining expansion microscopy, X-ray and EM
2. ReadoutStable long-term recording at 10⁵-neuron scale in behaving mammals; registering recorded and structural data from the same animal; BCI channel density and electrode lifetime
3. ModellingSystematic validation of the mapping from EM morphology to physiological parameters (MICrONS is the test bed); state-space models of neuromodulation; identifying and implementing biological learning rules
4. RunningMemory and communication design for spiking simulators at 10⁹–10¹¹ neurons; standardising body and environment models (generalising the NeuroMechFly line); automatic mapping onto neuromorphic hardware
5. PreservationQuantitative evaluation of ASC quality in human post-mortem brains; end-to-end demonstration of preserve → EM → reconstruct; intraoperative monitoring of perfusion quality
6. ValidationActivity-prediction benchmarks portable across species; protocols that eliminate degeneracy through perturbation response; a white paper defining emulation pass criteria

Because the problem is cross-disciplinary, there are entry points well outside neuroscience proper: machine learning (P1, P3), systems software and HPC (axis 4), microscopy, optics and materials (axes 1 and 5), control and robotics (axis 4), statistics and causal inference (axes 3 and 6), and bioethics and law (P5).

6.3 For Students

For students and career changers: a learning path.

6.4 For Funders & Policymakers

For funders and policymakers.

6.5 For Individuals

For individuals: six realistic options.

6.7 Do NOT

What not to do.

Five things to avoid

1. Do not pay any current service claiming to upload consciousness. As of 2026 no provider can scan or upload a personality. Chatbot-style "digital clones" replay records; they are not a transfer of the person.

2. Do not let hopes about uploading accelerate irreversible medical or end-of-life decisions. Preservation guarantees structural retention only and remains an unproven bet. Nothing in current science justifies letting "sooner is better" distort decisions about the timing of death — which is precisely what makes ethical review of assisted-death-compatible protocols contentious4.

3. Do not spread confident dates. Neither "arriving in 2045" nor "impossible forever" has documentary support. Speak in distributions (Chapter 4).

4. Do not run experiments on systems that might have subjectivity without a validation and ethics framework. Welfare and stopping criteria for animal emulations should be designed before the experiment. Metzinger's moratorium argument7 is strong, but the precautionary principle behind it is increasingly shared.

5. Do not treat brain data casually. Connectomes and neural recordings are the ultimate personal information. Confirm the protection framework (neurorights) before letting them onto a default path toward sharing or commercialisation.

Chapter summary
  • The field's rate limiters are five: proofreading automation, structure-to-dynamics inference, validation standards, preservation validation, and ethics infrastructure. From any position, the highest-value action is one that connects to one of these.
  • Because nearly all the data is open, students and individuals can start today (FlyWire, ZAPBench, OpenWorm).
  • For an individual the realistic order is understand → track → participate, with any preservation contract treated as optional insurance taken out in full knowledge of the scientific limits.
