Localizing functional regions of the cortex and deep-brain areas in epileptic patients is an important pre-surgical procedure prior to resection. This is often achieved using intra-cortical electrodes for both stimulation as well as recordings of Local Field Potentials (LFPs), concurrent to behavioral tasks related to language or motor function. To assist and improve accuracy in the identification of relevant brain networks associated to core cognitive functions, we present a novel interactive virtual reality system that aids in 3D visualization of precise electrode placement within cortical and sub-cortical regions of the patient and facilitates dynamical functional connectivity analysis of the aforementioned networks. The system is an extension of the BrainX3 tool [1][2][3], developed at the Laboratory for the Synthetic, Perceptive, Emotive and Cognitive Systems (SPECS).
