Put your head inside a brain
by Staff Writers
Geneva, Switzerland (SPX) Nov 17, 2017


Wearing VR goggles, users can put their head inside a virtual brain to explore 3-D neuroanatomical data.

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. A poster describing the system will be presented on Wednesday 15 November at the annual meeting of the Society for Neuroscience 2017, in Washington DC.

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 Stephane 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 - 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.

Dekalb IL (SPX) Nov 14, 2017
At Northern Illinois University, Dan Gebo opens a cabinet and pulls out a drawer full of thin plastic cases filled with clear gelatin capsules. Inside each numbered capsule is a tiny fossil - some are so small they rival the diminutive size of a mustard seed. It's hard to imagine that anyone would be able to recognize these flecks as fossils, much less link them to an ancient world that wa ... read more
