Drosophila Larva Mushroom Body

Interactive connectome visualization and CRN simulation results for the canonical decision-making circuit of the fruit fly larva.

About the data

Winding et al. (2023), Science: The complete brain connectome of the Drosophila melanogaster larva contains 3,016 neurons and over 500,000 synapses. The Mushroom Body (MB) is a canonical module for associative memory and learning. Architecture: projection neurons (PN) → Kenyon cells (KC, sparse coding) → output neurons (MBON, readout).
