Male Fruit Fly Connectome

NEW

Key Features

The dataset reconstructs the male fruit fly Drosophila melanogaster.
The map includes the ventral nerve cord and central nervous system.
The published reconstruction contains more than 166,000 neurons.
The map includes approximately 125 million synaptic connections.
AI-supported reconstruction turns microscopy sections into detailed neuronal structures.
HHMI Janelia experts annotated and proofread the connectome.
Neuroglancer enables interactive viewing of the large multidimensional dataset.
Male and female reconstructions enable study of sex differences and shared circuitry.

The reconstruction combines electron microscopy, computational alignment, AI segmentation, and expert proofreading. It contains more than 166,000 neurons and 125 million synaptic connections, including the ventral nerve cord. Researchers can inspect and download the reconstruction using tools such as the open-source Neuroglancer viewer.


The dataset supports circuit analysis, comparisons with female fruit fly maps, and investigation of structural variability. It is a scientific data resource rather than a consumer chatbot or diagnostic tool. Its public visualization and download pathways make detailed nervous-system anatomy accessible for further computational and experimental research.
