A 3D Voyage Inside A Brain Using VR Goggles

Amazing Applications For VR Goggles.

Virtual reality, once the dream of computer gamers everywhere is starting to prove it’s worth outside of the video game world. The medical community and industry is moving quickly to adapt the technology to solve some real world problems. Brain surgery is one of these critical endeavors that can be improved significantly by virtual reality.

A new immersive virtual reality (VR) experience now offers a unique way to visualize and interact with large volumes of 3D anatomical brain data. The system, developed by researchers from the Wyss Center for Bio and Neuroengineering and the University of Geneva, has applications in neurotechnology development, research and surgeon training.

Users wearing VR goggles can put their head inside a mouse brain and visualize the 3D structure at cellular resolution. Interactive hand-held pointers allow rapid, natural interaction with the data to highlight, select, slice and zoom

Developed to help handle the huge volumes of data now routinely produced by a new generation of high-resolution imaging techniques, the system is a novel tool to analyze data like that produced by the Wyss Center’s custom lightsheet microscope at Campus Biotech in Geneva, Switzerland.

Dr St├ęphane Pages, Staff Scientist at the Wyss Center and Senior Research Associate at the University of Geneva, who managed the microscope fabrication and is lead author of the paper said:

The immense data volumes produced by today’s high-performance microscopes are driving the development of new methods to visualize the brain. We have developed this virtual reality system to reconstruct cellular level neuroanatomical data in 3D space. The system provides a practical solution to experience, analyze and quickly understand these exquisite, high-resolution images.

One of only three in the world, the Wyss Center’s lightsheet microscope can image individual neurons which is five times thinner than a human hair. The latest viral tracing reveals the distribution of neuronal pathways and even dendritic spines, the micron sized protrusions that are communication points between neurons. Lightsheet microscope imaging is also a valuable tool to visualize and understand the detailed mechanical and biological interactions between novel neural implants and the brain, which is a focus of the Wyss Center’s translational neurotechnology program.

The VR system can also be readily combined with semi-automatic data analysis tools to accelerate the analysis of imaging data and simplify the identification of structures that can be difficult to recognize on a screen.
