Visualization of the human brain using complex images (tractography, functional connectivity, and functional imaging) is a challenge.
Different visualization solutions have been proposed. For example, Margulies et al. (2013), describe 2-D as well as 3-D neuroimaging visualization methods for anatomical, tractography, and functional connectivity data. Rojas et al. (2014), described a stereoscopic-related method to view neuroradiological 3-D images.
Virtual reality (VR) is an environment of scenes or real-life like objects, generated by computer technology, which create the feeling of being immersed in it. The environment is viewed by the user via a device usually known as glasses or virtual reality helmet.
Google Cardboard is a VR platform created by Google Inc. It is a low-cost device built using a piece of cardboard, 45 mm focal length lenses, magnets, VelcroTM, and optionally a near field communication tag (NFC), that uses a smartphone to generate VR stereoscopic 3D scenes with a broad field of view.
Here we describe an Android based mobile VR application that shows in 3D the seven standard functional connectivity networks with immersive characteristics.
