The conformation of anatomical structures is complex in the 3 spatial planes. Historically, anatomy teaching has been carried out using 2-dimensional representation, 3-dimensional physical models, or real bodies. Only recently it has been possible to create digital 3-dimensional anatomical models that can be explored online or downloaded. The aim of this work is to critically describe two of the best-known online tools for anatomical visualization (Anatomography and Biodigital Human), and to present a teaching experience in the neuroscience domain. Animated images of brain structures were created and later used in class, and students were asked about their interest and usefulness. Results indicated that the use of this kind of resource is interesting due to its flexibility, attractiveness and cost. 1 Corresponding author.

Evaluation of neuroanatomical training using a 3D visual reality model
Studies in health technology and informatics, 2012
As one of the more difficult components of any curricula, neuroanatomy poses many challenges to students - not only because of the numerous discrete structures, but also due to the complicated spatial relations between them, which must be learned. Traditional anatomical education uses 2D images with a focus on dissection. This approach tends to underestimate the cognitive leaps required between textbook, lecture, and dissection cases. With reduced anatomical teaching time available, and varying student spatial abilities, new techniques are needed for training. The goal of this study is to assess the improvement of trainee understanding of 3D brain anatomy, orientation, visualization, and navigation through the use of digital training regimes in comparison with current methods. Two subsets of health science and medical students were tested individually after being given a group lecture and either a pre- or post-dissection digital lab. Results suggest that exposure to a 3D digital lab...
Interactive 3D User Interfaces for Neuroanatomy Exploration
Web Information Systems and Technologies, 2009
Human neuroanatomy is extremely complex, and functional neuroanatomical pathways can not be dissected and easily visualized in an anatomy lab. Teaching students to see neuro-anatomical relationships over the extent of the neuraxis is challenging. The ability to internalize a 3D map of the neuraxis with the appropriate clinically relevant neuro-pathways superimposed is critical for medical students, as it facilitates long-term retention of the information as opposed to short-term memorization. Interactive 3D simulations can play a significant role in facilitating learning through engagement, immediate feedback and by providing realworld contexts.
Chapter 10: Students’ Recognition of the Human Nervous System in 3D Anatomical Illustrations
Advances in Social Science Research, 2020
In this chapter, we described the development of a multiple-choice instrument to explore sixth-grade students’ ability to recognise the place and shape of the basic components of the human nervous system from their 3D representations depicted in an interactive anatomical simulation. We also reported the findings from the use of the instrument with 86 Turkish sixth-grade students and the association of the instrument with a spatial ability test. In conclusion, 3D anatomical illustrations can be used to construct valid and reliable written instruments to elicit students’ understandings of human organs and organ systems. Furthermore, interactive anatomical simulations may facilitate the teaching and learning of these organs and organ systems.
Background The authors had previouslydeveloped AnaVu, a low-resource 3D visualization tool for stereoscopic projection of 3D models generated from annotated MRI neuroimaging data. However, its utility in neuroanatomical education needs to be quantified,and the students’ perspectives known. Methods A three-limb randomized controlled trial with crossover was designed. A sample (n=152) from the 2022 cohort of MBBS students at Government Medical College, Thiruvananthapuram (GMCT), was randomly selected from those who gave informed consent. After a one-hour introductory lecture on brainstem anatomy and a dissection session, students were randomized to three groups (S – stereo; M – Mono and C – Control). S was given a 20-minute demonstration on the brainstem lesson module in AnaVu in stereoscopic mode. M was given the same demonstration, but in monoscopic mode.The C group was taught using white-board drawn diagrams. Pre-intervention and post-intervention tests for four domains (basicrecal...
An interactive 3D framework for anatomical education
International Journal of Computer Assisted Radiology and Surgery, 2008
Object This paper presents a 3D framework for Anatomy teaching. We are mainly concerned with the proper understanding of human anatomical 3D structures. Materials and methods The main idea of our approach is taking an electronic book such as Henry Gray's Anatomy of the human body, and a set of 3D models properly labeled, and constructing the correct linking that allows users to perform mutual searches between both media. Results We implemented a system where learners can interactively explore textual descriptions and 3D visualizations. Conclusion Our approach allows easily performing two search tasks: first, the user may select a text region and get a view showing the objects that contain the selected structures, and second, using the interactive exploration of a 3D model
Does three‐dimensional anatomy improve student understanding?
Clinical Anatomy, 2019
We aim to provide an overview of the various digital three‐dimensional visualizations used for learning anatomy and to assess whether these improve medical students' understanding of anatomy compared to traditional learning methods. Furthermore, we evaluate the attitudes of the users of three‐dimensional visualizations. We included articles that compared advanced newer three‐dimensional anatomy visualization methods (i.e., virtual reality, augmented reality, and computer‐based three‐dimensional visualizations) to traditional methods that have been used for a long time (i.e., cadaver and textbooks) with regard to users' understanding of anatomy. Of the 1,148 articles identified, 21 articles reported data on the effectiveness of using three‐dimensional visualization methods compared to two‐dimensional methods. Twelve articles found that three‐dimensional visualization is a significantly more effective learning method compared to traditional methods, whereas nine articles did n...
Development of a 3D Printed Neuroanatomy Teaching Model
University of Ottawa Journal of Medicine, 2019
Gross anatomy has been seen as one of the basic bodies of knowledge that must be mastered as part of medical training. Likewise, neuroanatomy has been seen as foundational to clinical neurosciences. However, Neuroanatomy is different from gross anatomy and this is due to the complexity of the central nervous system, moreover, some of its structures cannot be dissected or demonstrated in anatomy cadaveric lab. The use of anatomical models in medical curricula has been reported as an effective way in teaching and learning anatomy. They have been used to replace cadaveric material when the latter is difficult to acquire, or when the anatomical structures cannot be dissected like the brain ventricles for instance, moreover they have the privilege of visualizing the structures in a 3 dimensional modality. The goal of this study was to create a 3 D printed neuroanatomy model in order to complement the University of Ottawa anatomy models’ library, and help medical students visualize the pa...
Three-Dimensional E-Learning Application for Anatomy and Physiology of Brain
International Journal of Integrated Engineering
Neurology is one of the most challenging areas to master among the medical students owing to the complexity of the structures and their spatial arrangement. Teaching dissection and prosecutions during the anatomy lab sessions are not necessarily effective due to large class strength. To complement teaching and learning on this subject matter, a web-based, 3D interactive e-learning application called the Brainy is proposed to help medical students and lecturers to learn and teach neurology in an efficient way. Brainy merges virtual technology with learning by breaking down the brain information into three different parts, namely the lobes of brain, parts of brain, and structures of brain. Every time a student chooses to study a part of brain, the 3D model of selected part will be complemented with brief description of anatomy, physiology and applied aspects. Thus, the student will no longer need to switch different books while studying. Brainy is thus a versatile application for students to study brain in a fun and engaging way.
Construction of a 3-D anatomical model for teaching temporal lobectomy
Computers in Biology and Medicine, 2012
Although we live and work in 3 dimensional space, most of the anatomical teaching during medical school is done on 2-D (books, TV and computer screens, etc). 3-D spatial abilities are essential for a surgeon but teaching spatial skills in a non-threatening and safe educational environment is a much more difficult pedagogical task. Currently, initial anatomical knowledge formation or specific surgical anatomy techniques, are taught either in the OR itself, or in cadaveric labs; which means that the trainee has only limited exposure.
