Excision of whole intact mouse brain

Area of Science:

• Neuroscience
• Biomechanical Engineering
• Materials Science

Background:

• Accurate mechanical characterization of brain tissue is vital for understanding normal physiology and conditions like traumatic brain injury.
• Undamaged, unfixed brain tissue is essential for reliable mechanical property measurements.
• Current brain tissue excision methods can cause damage, compromising experimental results.

Purpose of the Study:

• To present a refined method for excising intact mouse brains.
• To ensure the preservation of normal, undamaged brain tissue mechanical properties.
• To facilitate reliable biomechanical studies of brain tissue.

Main Methods:

• Resection of the scalp to expose the anterior skull.
• Careful cranial bone resection along sutures using a scalpel.
• Resection of connective tissue for brain removal from the cranial vault.

Main Results:

• The presented method allows for the complete and intact removal of the mouse brain.
• This technique minimizes induced damage during tissue excision.
• Preserves the native mechanical properties of the brain tissue.

Conclusions:

• The described method provides a reliable approach for obtaining undamaged mouse brain samples.
• This technique is critical for accurate biomechanical characterization of healthy brain tissue.
• Enables more precise research into brain tissue mechanics and injury.
