A team of researchers co-led by the University of Pennsylvania has developed and tested a new high-resolution, ultra-thin device capable of recording brain activity from the cortical surface without having to use penetrating electrodes. The device could make possible a whole new generation of brain-computer interfaces for treating neurological and psychiatric illness and research.
The work was published in Nature Neuroscience.
"The new technology we have created can conform to the brain's unique geometry, and records and maps activity at resolutions that have not been possible before," says Brian Litt, MD, the study's senior author and Associate Professor of Neurology at the Perelman School of Medicine and Bioengineering at the University of Pennsylvania. "Using this device, we can explore the brain networks underlying normal function and disease with much more precision, and its likely to change our understanding of memory, vision, hearing and many other normal functions and diseases." For our patients, implantable brain devices could be inserted in less invasive operations and, by mapping circuits involved in epilepsy, paralysis, depression and other 'network brain disorders' in sufficient detail, this could allow us to intervene to make patients better, Litt said.

Hope is but the first step upon the road to disappointment.
