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.

Seizures are abnormal and recurrent brain activities, and sometimes, treatment includes resecting a region where seizures happen and propagate. In specific evaluation before resection surgery, EEG electrodes are implanted in the brain to temporally record a seizure propagation and generating zone(s). A magnetic resonance imaging (MRI) scan can help neurologists to spatially locate the electrodes inside the brain for the analysis of the seizure start and spread. According to two experienced neuroscientists, using two different tools for the analysis of the EEG and neuroimage with a 2D representation is the most common and traditional way for specialists to plan surgery in this case (Figure 1).

We developed a tool that (a) integrates the medical data sets and (b) creates an immersive visualization in a physical space to aid neurologists in the task. Our tool, EPES (Epilepsy Pre-Evaluation Space), visualizes seizure propagation through the brain while the EEG panel is placed in the 3D space for showing the required information (Figure 2).
