Nanofibres help rebuild brain cells
MIT scientists have used nanotechnology to help restore the sight of hamsters blinded by a severed tract in their brains' visual system
Massachusetts Institute of Technology (MIT) bioengineers and neuroscientists have invented a biodegradable scaffold of nanofibres through which brain cells can regrow to repair injury. The technique was proven in hamsters blinded by a severed tract in their brains' visual system, which had their sight partially restored within weeks.
This method may one day help patients with traumatic brain injuries, spinal cord injuries and stroke. The study is the first that uses nanotechnology to repair and heal the brain and restore function of a damaged brain region.
