Visualization of Functional Connectivity Networks

Posted on Posted in VR

The visualization of complex neuroimages such as tractography, functional connectivity and functional imaging, is a difficult task that imply how to show the targets of this parametrical neuroimages in a manner to offer good information to understand it. In previous works we had shown some visualization techniques for neuroimages (such as anaglyph, augmented reality, virtual reality using Cardboard, etc.; Rojas et al, 2014, Rojas et al., 2015, Rojas et al., 2016).


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 specific device usually known as glasses or virtual reality helmet. There are different types of VR devices: VR glasses (such as Oculus Rift, HTC Vive, Sony PlayStation VR, Samsung Gear VR, and Google Daydream View), and cheaper devices such as Google Cardboard (Google Inc.).


Here we describe a Windows based HTC Vive VR system that allows viewing seven Yeo functional connectivity networks (Yeo, 2011), with EEG 10-20 electrodes superimposed to that functional connectivity networks.


This Application was presented in Poster Session during the OHBM Conference.
