  • Implementation of a standardization procedure to align individual 3D confocal microscopy images to a common coordinate system.
  • Computation of average intensities per voxel and an integrated data management system.

    • Main Results:

    • The VIB protocol enables quantitative assessment, comparison, and presentation of neuroanatomical data.
    • Facilitates direct comparison of gene expression patterns and analysis of interindividual variability.
    • Provides tools for brain region volumetry and characterization of mutant phenotypes without requiring programming skills.

    Conclusions:

    • Standardizing brains and gene expression patterns offers a novel approach to studying biological shape and variability.
    • The VIB protocol provides initial tools for standardization in Drosophila neuroanatomy.
    • The VIB script suite is freely available for research use.
