CHIMERA
Drosophila larval connectome experiment linking a 1,373-neuron circuit to a MuJoCo body and a language-to-stimulus interface. Larval circuit subset.
Neurons are simulated — leaky integrate-and-fire or better — with documented, tuned parameters.
Dispute this rating →The evidence
No evidence, no level.Neurons are leaky integrate-and-fire units with explicit time constant, threshold, reset and refractory period.

1,373 neurons from the Winding et al. (2023) Drosophila larva connectome simulated as leaky integrate-and-fire units with stated constants (TAU 8.0, V_REST -70, V_TH -52, V_RESET -75, REFRAC 2), driving a MuJoCo body. A Qwen 0.5B model only parses the typed text into sensory channel activations; it is not part of the brain. Documented membrane dynamics earn L1. Not L2: the adjacency matrix self.W is loaded from a .npy file and appears exactly three times in the codebase - the load, a nonzero count for the banner, and the read in step() - so no synapse is ever written. The project's own roadmap lists Hebbian learning as Planned, not Done.
