The "Virtual Brain" project is a joint venture based on the JARA cooperation, fostering the transfer of knowledge across several scientific domains. Computer scientists from JARA-HPC provide their know-how to neuroscientists from the institutes INM-1 and INM-2, subsumed in the JARA-BRAIN division, to support the exploration of cortical areas and their interconnection.
Stereoscopic visualization of probability maps is an important step towards understanding the spatial alignment and size of the cortical areas and their wiring by fiber tracts, while real-time interaction with the displayed content represents a canonical way of data analysis. Both are vital ingredients of any virtual reality system.
Using interaction devices, the user is able to examine internal structures, otherwise covered by the cortex. Moreover, by semi-opaque display of probabilistic fiber tracts scientists get an immediate idea of the displayed data.
A combination of those techniques allows to draw conclusions about the relationship between fiber tracts and anatomical structures.
