With advancement in research in a given field, there should be parallel development in visualisation methods to understand the data accrued. 3D visualisation and interactive visual applications can facilitate synthesis and understanding of high dimensional data. This concept has been applied within varying fields of research, though it has yet to be explored significantly in the field of functional neural mapping. This project documents the development of an interactive application for mobile and tablet devices visualising multivariate functional mapping of fMRI data within a 3D structural model of the brain. The application is developed as a proof of concept for the efficacy of interactive 3D visualisation for representing research in functional mapping, as well as the potential for Unity 3D game engines use as a visualisation tool for the complex data involved in the research of functional neural activity.
