A Tangible Educative 3D Printed Atlas of the Rat Brain

Area of Science:

• Neuroscience
• Biology Education
• Anatomical Modeling

Background:

• Traditional methods for teaching brain anatomy, such as Magnetic Resonance (MR) images and histological sections, lack dynamism and intuitiveness.
• Understanding complex 3D brain structures can be challenging with 2D representations.

Purpose of the Study:

• To develop an educational, 3D printed rat brain model for improved understanding of neuroanatomy.
• To provide a tangible and interactive tool for teaching brain structure and organization.

Main Methods:

• Designing and manufacturing an anatomically accurate, multi-part 3D printed rat brain model using poly(lactic acid) (PLA).
• The model is scaled up and designed for easy assembly and disassembly of its eight major divisions.
• Utilizing 3D printing techniques for fabrication and post-processing (smoothing, modification).

Main Results:

• A functional, dissectible 3D printed rat brain model was successfully created.
• The model facilitates hands-on learning of the rat brain's 3D organization and major anatomical divisions.
• The methodology offers a viable alternative to animal dissection for anatomy education.

Conclusions:

• The 3D printed rat brain model serves as an effective, intuitive educational tool for neuroanatomy.
• This approach enhances student comprehension of complex brain structures.
• The methodology is adaptable for broader applications in clinical and pre-clinical research and education.
