is a novel immersive analytics system that facilitates the visual inspection of structural and functional connectome datasets. The representation of the human connectome as a graph enables neuroscientists to apply network-theoretic approaches in order to explore its complex characteristics. With NeuroCave
, brain researchers can interact with the connectome— either in a standard desktop environment or while wearing portable VR headsets (such as Oculus Rift, Samsung Gear, or Google Daydream VR platforms)— in any co-ordinate system or topological space, as well as cluster brain regions into different modules on demand. Furthermore, a default side-by-side layout enables simultaneous, synchronized manipulation in 3D, utilizing modern GPU hardware architecture, and facilitates comparison tasks across different subjects or diagnostic groups or longitudinally within the same subject. Visual clutter is mitigated using a state-of-the-art edge bundling technique and through an interactive layout strategy, while modular structure is optimally positioned in 3D exploiting mathematical properties of platonic solids. NeuroCave
provides new functionality to support a range of analysis tasks not available in other visualization software platforms. NeuroCave
was developed in collaboration with the Collaborative Neuroimaging Environment for Connectomics (CoNECt@UIC
), and first presented at NetSci 2017
, the International School and Conference on Network Science.
