Area of Science:

Neuroscience
Anatomy
Medical Research

Background:

Brain banking is crucial for studying neurological diseases, physiology, and neuroanatomy.
Detailed methods for whole brain extraction are scarce, potentially leading to tissue artifacts.
Standardized brain removal is essential for reliable post-mortem analysis.

Purpose of the Study:

To describe and evaluate a standardized method for whole human brain extraction for fixed tissue banking.
To document procedural steps, time requirements, and artifact frequency.
To offer insights into optimizing brain extraction for research.

Main Methods:

A sequential craniectomy technique involving circumferential and sagittal cuts.
A posterior approach for dura mater transection.
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.
