Scientists have spent decades trying to build machines that talk to the brain. Robust and reliable neural interfaces have long been a holy grail in the field of neuroscience. The hope is that a new wave of research programs, including the BRAIN Initiative and Human Connectome, among others, could lead to groundbreaking technologies for helping people with brain-related diseases. If effective, these new therapies could even, some argue, bring about the end of disability.
Some believe that developing such interfaces will require advanced brain implants that are still a decade or more away. More recently, though, neuroscientists—as well as a legion of “brain hackers”—have turned to powerful new sensing, processing, and prototyping tools to explore a host of non-invasive techniques to stimulate the brain. Some of these methods, proponents say, could benefit not only patients who suffer from disease orinjury, but also healthy individuals, who would be able to learn faster, acquire better math skills, improve their memory capabilities, and even boost their creativity. …[Read more]
