Description
A synapse-resolution reconstruction and annotation of the adult female Drosophila melanogaster central nervous system, spanning both the brain and ventral nerve cord. The dataset includes cell annotations, neurotransmitter predictions, connectivity matrices, and NBLAST similarity results to other fly connectomes, providing a stable reference for the analyses in the associated 2025 manuscript. Data is based on CAVE materialization 888, snapshotted on April 17, 2026, and is accessible via FlyWire Codex, the BANC portal, and BossDB.
Use Cases
Analyze neural connectivity and circuit motifs based on the provided synapse-resolution connectivity matrices.
Compare neuron morphology and homology across connectomes using the included NBLAST similarity results and aligned metadata.
Model neural dynamics and compute influence scores using the linear dynamical model and all-to-all influence matrix described in the manuscript.
Visualize and explore neuron reconstructions using the provided L2 skeletal representations and colorMIP images.
Strengths
Synapse-resolution reconstruction of the complete adult female Drosophila central nervous system, including both brain and ventral nerve cord.
Includes multiple data layers: cell annotations, neurotransmitter predictions, connectivity matrices (v2 and v3 snapshots), and cross-dataset neuron comparisons.
Provides a stable, versioned snapshot (CAVE materialization 888) from April 17, 2026, linked to a published manuscript.
Aligned with other major fly connectomes (FAFB, FANC, HemiBrain, MANC) for visual and computational cross-dataset comparison.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment for specific computational tasks.
Data is specific to the adult female Drosophila melanogaster, limiting generalizability to other species or sexes.
Provenance
Source
BANC Connectome Dataverse, associated with the manuscript 'Distributed control circuits across a brain-and-cord connectome'.
