Neuroanatomy is a complicated subject for students, scientists and physicians which could benefit from modern three dimensional (3D) applications. One of these applications is called GreyMapp, which provides a detailed overview of the 3D anatomy of the human brain by integrating non-augmented- and augmented reality (non-AR and AR respectively).

Using GreyMapp was found to lead to a proper understanding of 3D neuroanatomy without exerting a disproportional amount of cognitive load. The cognitive load theory assumes that the human cognitive system has a limited working memory which should not be exceeded. Generally, cognitive load is divided into three categories: intrinsic, extraneous and germane cognitive load and each subset is suggested to be affected by non-AR- and AR-features. Research showed that cross-sectional learning was negatively impacted by use of GreyMapp.

Therefore, to optimize cross-sectional learning, 7 Tesla MR slices of the corresponding brain were added to all modalities of GreyMapp. By interleaving all 3D technologies with the 2D MRI slices, GreyMapp became an all-round educational tool which enables students to learn by the anytime, anywhere principle. The gamification principle, on the other hand, forms the next step.

By use of conventional VR-systems, students will be allowed to navigate through the ventricular system. This game will allow students to earn points when recognizing surrounding structures correctly. For less advanced learners (i.e., patients), 3D applications like GreyMapp can be used as an educational tool which will help to understand their neurological deficits. For more advanced learners like scientists and physicians, more complex environments will be created.

One example of a clinically relevant learning environment concerns the placement of a ventricular drain by use of AR. By learning such invasive techniques in an AR setting, clinical skills will be trained without the possibly negative side-effects for patients.
