None of the science is ours.

Application framework: routing, rendering and the build pipeline.

Interface runtime for the application shell and control surfaces.

Utility CSS layer. The design tokens are first-party custom properties.

Build-time type system for the application, engine and worker protocol.

Interface and display typefaces, self-hosted. No runtime font requests.

Monospaced typeface for numerical and technical text, self-hosted.

Type declarations for the WebGPU API. Build-time only.

The complete adult Drosophila connectome. Not bundled, not redistributed and not downloaded by this project. Cited as the reference dataset and as the target of the documented import adapter, which leaves the data with the researcher who obtained it under its own licence.

Central-brain reconstruction used as a literature source for circuit statistics. No data from it is bundled or redistributed here.

The simulator in which the reference Drosophila model was written. NeuroSim does not embed, wrap, port or execute it. The same published equations are implemented natively in TypeScript.

GPU spiking-network simulator, referenced as prior art for kernel structure. No GeNN code is used, ported or linked.

Physics engine and anatomical fly body model, referenced as the proper approach to embodied fly simulation. The NeuroSim agent is an independent kinematic model and uses neither.

Referenced as the standard framework for connectome-constrained model fitting in the literature. Not a dependency: the browser platform has no Python runtime.

The complete adult Drosophila connectome: 139,255 neurons and roughly 54.5 million synapses. Cited as the reference dataset for connectome-scale work and as the target of the data-import path. Its data is not bundled with this site.

Cell-type annotation and neurotransmitter assignment across the FlyWire connectome; the basis for treating GABAergic and glutamatergic cells as inhibitory.

The leaky integrate-and-fire parameterisation used by the NeuroSim engine: −52 mV rest, −45 mV threshold, 20 ms membrane time constant, 5 ms synaptic decay, 2.2 ms refractory period, 1.8 ms propagation delay and 0.275 mV per synapse.

The random-sampling rule used to wire projection neurons onto Kenyon cells (~6 claws per cell).

Compartmental organisation of the mushroom body: MBON and DAN counts, and their compartment-matched connectivity.

The role of the APL neuron as a global inhibitory feedback loop enforcing sparse Kenyon-cell coding.

Quantitative mushroom-body connectivity used to sanity-check the generated circuit's degree statistics.

The E-PG / P-EN / Δ7 wiring of the central-complex ring attractor, including the ±1 wedge offset that rotates the bump.

Central-complex cell types and network motifs underlying the heading-direction circuit.

The L1→Mi1/Tm3→T4 ON pathway and the offset-arm structure of the elementary motion detector.

Comprehensive ON-pathway connectivity, including CT1's role in null-direction suppression.

The L2→Tm1/Tm2→T5 OFF pathway and its symmetry with the ON pathway.

The hemibrain connectome; a second independent source for the circuit statistics used here.

Reference for embodied fly simulation. NeuroSim's browser agent is a far simpler kinematic model and does not use this work's body model or code.

The simulator in which the reference Drosophila LIF model was written. NeuroSim implements the same equations natively for the browser; it does not run or embed Brian 2.

GeNN's approach to GPU spiking simulation, which informed the structure of the NeuroSim WebGPU kernel.
