Exploring the Drosophila Ventral Nerve Cord
High-fidelity connectome-scale simulation powered by Brian2 and Janelia FlyWire data.
FlyBrian is an advanced neural circuit simulation platform designed to model and analyze the complex neural networks of the Drosophila melanogaster ventral nerve cord (VNC).
Built on cutting-edge computational neuroscience frameworks, our platform integrates high-resolution connectome data from Janelia Research Campus with sophisticated biophysical neuron models to enable detailed circuit-level simulations.
Researchers can explore neural dynamics, test hypotheses about circuit function, and investigate how specific neurons contribute to behavior through targeted stimulation and silencing experiments.

Launch simulations, inspect connectome data, and review experiment output from the workstation, the lab bench, or a phone between meetings.
