Fruit Fly Lab
Interactive FlyWire v783 whole-brain LIF simulation with stimulus controls and activity visualization. Research prototype.
Neurons are simulated — leaky integrate-and-fire or better — with documented, tuned parameters.

No evidence, no level.The LIF equations and constants are transcribed from the published Shiu et al. 2024 whole-brain model.

A 139,255-neuron FlyWire FAFB v783 simulation running the Shiu et al. (2024) whole-brain LIF model, transcribed constant-for-constant with an equivalence test against a literal Brian2 reference. Voltages evolve under a documented, published neuron model, so L1 is comfortably earned. Not L2: the engine's step() reads self.wdata to schedule delayed synaptic events but never writes to it, and the project's own assumptions document states plainly that there is no synaptic plasticity, facilitation, depression or adaptation, and that the mushroom body 'is present and wired, but cannot learn here'. The escape-circuit experiments work by silencing neurons, which is a lesion, not plasticity.
