GE Brain Health Initiative

GE has launched a new Brain Health Initiative linking numerous entities within the company such as GE Healthcare, GE Ventures & Healthymagination, and GE’s Global Research Center.

The Initiative will build on and coordinate multiple efforts within the company, including corporate venture capital, open innovation, R&D, and health care lines of business. This includes previously announced efforts at GE, such as the work that the company has done to convene the traumatic brain injury community and support for “Brain Trust” meetings of thought leaders.

Commercializing auditory neuroscience.

Dr. Donald "Lloyd" Watts has worked as an engineer at Microtel Pacific Research, Synaptics and Arithmos. In 1997, he joined Paul Allen's Interval Research Corporation and continued his research in reverse-engineering the human auditory pathway. In 2000, he founded Audience, Inc., to commercialize his research, with investment from Paul Allen, Carver Mead and Allan Crawford. He served as Chairman and Chief Executive Officer from 2000-2005, leading the development of the company's core technologies.

Turning off Parkinson’s and depression

Deep brain stimulation is becoming very precise. This technique allows surgeons to place electrodes in almost any area of the brain, and turn them up or down -- like a radio dial or thermostat -- to correct dysfunction. Andres Lozano offers a dramatic look at emerging techniques, in which a woman with Parkinson's instantly stops shaking and brain areas eroded by Alzheimer's are brought back to life.

Taking genetics out of optogenetics

Light can be used to activate normal, non-genetically modified neurons through the use of targeted gold nanoparticles—a new technique that could hold promise for treating diseases such as macular degeneration.

“Many optogenetic experimental designs can now be applied to completely normal tissues or animals, greatly extending the scope of these research tools and possibly allowing for new therapies involving neuronal photostimulation.”

Bioelectricity can Control Brain Development

Bioelectrical signals among cells control and instruct embryonic brain development and manipulating these signals can repair genetic defects and induce development of healthy brain tissue in locations where it would not ordinarily grow.

These bioelectric signals are implemented by changes in the voltage difference across cell membranes – called the cellular resting potential -- and the patterns of differential voltages across anatomical regions.
