  • Application of the protocol to 105 human whole-body donors, with artifact assessment.

    • Main Results:

    • The described craniectomy method was successfully applied to 105 donors.
    • Procedural optimization and technician experience (5-10 cases) improve extraction effectiveness.
    • In situ immersion fixation can increase tissue stiffness but may slow chemical diffusion.

    Conclusions:

    • Optimized whole brain extraction protocols enhance tissue quality for neuroscience research.
    • Improved brain tissue preservation supports advancements in diagnosing and treating neurological disorders.
    • Standardized extraction methods are vital for reproducible brain banking and research outcomes.
