Development of interactive MRI-based 3D visualization tools for neuroanatomy education in Latin America

Area of Science:

• Neuroscience and Education Technology
• Application of advanced visualization in anatomy education

Background:

• Neuroanatomy is a challenging subject for students.
• Three-dimensional (3D) visualizations and interactive tools offer personalized engagement for learning complex structures.
• There is a need for accessible and evaluated interactive neuroanatomy educational tools, particularly in Latin America.

Purpose of the Study:

• To create and evaluate the educational impact of interactive 3D neuroanatomy visualization tools.
• To address the gap in interactive neuroanatomy education resources in Latin America.

Main Methods:

• Developed a 3D neuroanatomy visualization using magnetic resonance imaging (MRI) and post-processing.
• Integrated the visualization into a web-based tool and a CAVE (Cave Automatic Virtual Environment) virtual reality system.
• Assessed impact via student grades and faculty/student questionnaires in an undergraduate neuroanatomy course.

Main Results:

• Tools received high ratings for enjoyment, usefulness, and self-study potential from students and faculty.
• Student grades showed a statistically significant improvement post-implementation (p=0.05, Cohen's d=0.44).
• Simulator sickness was noted as a factor impacting user experience in the virtual reality environment.

Conclusions:

• Interactive 3D neuroanatomy tools are well-received and show potential for enhancing student learning and grades.
• The developed tools contribute to filling the need for interactive neuroanatomy education in Latin America.
• Larger, controlled studies are recommended to further validate the educational efficacy and address challenges like simulator sickness.
