ABSTRACT Neuroscientists traditionally use information representations on 2D displays to analyze multivariate spatial and temporal datasets for an evaluation stage before neurosurgery. However, it is challenging to mentally integrate the information from these datasets. Our immersive tool aims to help neuroscientists to understand spatiotemporal phenomena inside a brain during the evaluation. We refined our tool through different phases by gathering feedback from the medical experts. Early feedback from neurologists suggests that using virtual reality for epilepsy presurgical evaluation can be useful in the future.
