Visualizing a beautiful mind

How does an autistic child take in information when he sits in a classroom abuzz with social activity? How long does it take someone with multiple sclerosis, which slows activity in the brain, to process the light bouncing off the windshield while she drives?

Until recently, the answers to basic questions of how diseases affect the brain – much less the ways to treat them – were lost to the limitations on how scientists could study brain function under real-world conditions. Most technology immobilized subjects inside big, noisy machines or tethered them to computers that made it impossible to simulate what it’s really like to live and interact in a complex world.

But now UC San Francisco neuroscientist Adam Gazzaley, MD, PhD, is hoping to paint a fuller picture of what is happening in the minds and bodies of those suffering from brain disease with his new lab, Neuroscape, which bridges the worlds of neuroscience and high-tech.

In the Neuroscape lab, wireless and mobile technologies set research participants free to move around and interact inside 3-D environments, while scientists make functional recordings with an array of technologies. Gazzaley hopes this will bring his field closer to understanding how complex neurological and psychiatric diseases really work and help doctors like him repurpose technologies built for fitness or fun into targeted therapies for their patients.

“I want us to have a platform that enables us to be more creative and aggressive in thinking how software and hardware can be a new medicine to improve brain health,” said Gazzaley, an associate professor of neurology, physiology and psychiatry and director of the UCSF Neuroscience Imaging Center. “Often, high-tech innovations take a decade to move beyond the entertainment industry and reach science and medicine. That needs to change.”

As a demonstration of what Neuroscape can do, Gazzaley’s team created new imaging technology that he calls GlassBrain, in collaboration with the Swartz Center at UC San Diego and Nvidia, which makes high-end computational computer chips. GlassBrain creates vivid, color visualizations of the structures of the brain and the white matter that connects them, as they pulse with electrical activity in real time.

These brain waves are recorded through electroencephalography (EEG), which measures electrical potentials on the scalp. Ordinary EEG recordings look like wavy horizontal lines, but GlassBrain turns the data into bursts of rhythmic activity that speed along golden spaghetti-like connections threading through a glowing, multi-colored glass-like image of a brain. Gazzaley is now looking at how to feed this information back to his subjects, for example by using the data from real-time EEG to make video games that adapt as people play them to selectively challenge weak brain processes.

Gazzaley has already used the technology to image the brain of former Grateful Dead drummer Mickey Hart as he plays a hypnotic, electronic beat on a Roland digital percussion device with NeuroDrummer, a game the Gazzaley Lab is designing to enhance brain function through rhythmic training. Hart, whose brain is healthy, is collaborating with Gazzaley to develop the game and performed on NeuroDrummer while immersed in virtual reality on an Oculus Rift at the Neuroscape lab opening on March 5.

The Neuroscape lab will be available to all UCSF researchers who study the brain. And Gazzaley ultimately hopes it will aid in the development of therapies to treat diseases as various as Alzheimer’s, post-traumatic stress disorder, attention deficit and hyperactivity disorder, schizophrenia, autism, depression and multiple sclerosis.

UCSF is a leading university dedicated to promoting health worldwide through advanced biomedical research, graduate-level education in the life sciences and health professions, and excellence in patient care. It includes top-ranked graduate schools of dentistry, medicine, nursing and pharmacy, a graduate division with nationally renowned programs in basic biomedical, translational and population sciences, as well as a preeminent biomedical research enterprise and two top-ranked hospitals, UCSF Medical Center and UCSF Benioff Children’s Hospital.

    This is a amazing article that is a big inspiration because of the work that is being done. This new technology that is being developed and used to study the way the brain works on a more visual way will change how we see disorders in the brain. With this technology docters and scientists will be able to see speisific areas and things that have a impact on the brain, as is mentioned in the article hard questions will be answered with this technology like how do autistic children concentrate in a noisy clasroom. By understanding these questions and answers we will also understand how to work with children with brain disorders such as autism, we will know how to teach them and how to treat them so that they can be in control of their brain even though they have a disordet. I personally think this is a huge step forward in the medical field and by using this technology we will be able to help people have beter lives with brain disorders.
