Progress in connecting neural stimulation to physical body control is transforming the development of prosthetics and the therapeutic training of people with disabilities, according to new research. The results were presented at Neuroscience 2018, the annual meeting of the Society for Neuroscience, the world's largest source of emerging news on brain science and health.
As understanding of neuronal functions and their interactions allies with technical advances, scientists are developing new and improved prostheses and therapies to improve the quality of life for people with paralysis, stroke, or blindness . Electrical signals that stimulate specific regions of the brain or body can prevent damage to the spine or eyes and activate target areas, causing the brain to process motion or vision as efficiently as possible.
New discoveries today show that:
Advances in the precision and strength of computer-controlled, brain-controlled hand movements can help people with quadriplegia and those with hand paralysis begin to incorporate electrical stimulation-based prostheses in their body. daily life (Gaurav Sharma, abstract 271.01). The use of avatars to provide stroke patients with visual feedback associated with real-time electronic feedback has improved the use of motor function even years after stroke ( Christoph Guger, abstract 271.14). A new hand prosthesis system is the first prosthesis designed for regular home use to restore task-related sensations in an amputee (Ranu Jung, Abstract 404.10, see summary attached). A new brain stimulation technique called "dynamic current steering" helps restore the limited vision of blind people (Michael Beauchamp, Abstract 226.09). An assistive device that combines visual vision and sound can help blind people perform daily tasks such as identifying and locating people and objects around them (Michael Paradiso, abstract 226.04) . "The advances being made today are expanding the possibilities of brain-machine interfaces," said moderator Emery University's Chethan Pandarinath, Ph.D., whose work interpret how the brain represents information and its intention to design assistive devices for people with disabilities. . "The neuroscience advances and range of techniques presented offer new assistive devices and treatment strategies for people with disabilities, and also open the door to a deeper understanding of how our brain translates intention." in shares.
