When will artificial electrical synapses (Duke LinCx) or connectome-based activity prediction (Eon) reach first human use?

67%Belief the predicted event happens at all — every “yes / by-a-date” outcome added together. “Other” is tracked as its own third slice.
Outcomes
Resolution criteria
The first claimed use of artificial-synapse or connectome-prediction technology in a human, in a registered study. Resolution horizon: 2040-12-31. Source: registry, publication.
Description
Two 2026 advances in engineering brain wiring, both still far from humans. Duke's LinCx is an artificial electrical synapse: engineered fish-derived proteins that dock only with a matching partner and pass electrical current between two chosen neurons, so researchers can add a brand-new connection to a circuit instead of repairing a broken one. In mice and worms it altered social behavior, stress resilience, and temperature-seeking (Nature, May 2026). Background: https://today.duke.edu/2026/05/new-wire-points-new-treatment-approach-neurological-disorders Eon (Eon Systems) does connectome-based activity prediction: start from a wiring map of a brain, then use deep learning to predict what those neurons will actually do — first demonstrated on the fruit-fly visual system inside a virtual embodied fly. Background: https://eon.systems/updates/embodied-brain-emulation This market asks when either line of work first reaches a human in a registered study. Resolution horizon: 2040.
Evidence & context
Trials, publications and reports our research found on this prognosis. Each links to the original source.
This is a 2026 Nature publication on an engineered electrical synapse for long-term editing of brain circuits. It is directly relevant to the artificial-synapse side of the prediction because it evidences technical progress toward eventual human use, though the provided excerpt does not indicate a human study or a registered trial.
This is a Duke School of Medicine news article describing a preclinical study on electrically rewiring brain circuits, which appears directly related to Duke's artificial-synapse/LinCx line of work. It is not a human study or registered trial, but it is meaningful background evidence on the maturity and trajectory of the technology.
This is a news article describing Duke preclinical research on engineered brain rewiring, which is directionally relevant to artificial electrical synapse approaches such as LinCx. It is not itself a registered human study or publication record, but it provides indirect evidence that the technology is still at an early research stage.
