Virtual Fly Brain

Virtual Fly Brain integrates and organizes multi-modal Drosophila neurobiology data to enable anatomical and molecular analysis of the larval and adult central nervous system.

Key Features:

• Data integration and FAIR compliance: Integrates 3D images of neurons and brain regions, connectomic maps, transcriptomic profiles, and reagent expression datasets while adhering to Findability, Accessibility, Interoperability, and Reusability principles.
• Search functionality: Supports text-based queries, image search, 3D image-based queries, and queries by neuron type (e.g., dopaminergic neurons) or properties (e.g., synaptic inputs in the antennal lobe).
• Visualization tools: Provides cross-registered 3D image visualization with linked 2D and 3D representations of neural structures and connectivity.
• Data download and licensing: Enables download of data under open licenses for use outside the platform.
• Curated descriptions: Includes literature-curated descriptions of cell types and brain regions.

Scientific Applications:

• Anatomical and molecular circuit analysis: Supports integrated anatomical and molecular characterization of Drosophila neural circuits in larval and adult CNS.
• Hypothesis generation about brain function and behavior: Facilitates generation of hypotheses linking neural anatomy, connectivity, and gene expression to behavior.
• Experimental design and reagent selection: Assists identification of appropriate reagents and experimental targets using integrated expression and anatomical data.
• Research in neurogenetics, development, and systems neuroscience: Serves studies in neurogenetics, developmental biology, and systems neuroscience by providing multi-modal datasets and derived maps.

Methodology:

Computational integration of 3D images, connectomic maps, transcriptomic profiles, and reagent expression data using algorithms for data linking and cross-registration of 3D images.
