In traditional biology education, there are many abstract biological models and phenomena. However, the traditional classroom teaching format often fails to vividly and concretely present knowledge, making it difficult for students to imagine and leading to difficulties in understanding. Virtual reality technology addresses this issue by constructing an immersive learning environment, providing learners with threedimensional visualizations and immersive interactive experiences of biological processes. This approach makes knowledge more tangible, aiding learners in better understanding biological concepts. This study focuses on the nervous system as a classic case, creating an immersive learning environment. In addition to building realistic scenes, various interactive features such as joystick interaction, scene roaming, and automatic audio explanations have been implemented. These functionalities, spanning from the macro to the micro level, assist learners in comprehending the structure and functional characteristics of the nervous system.
