UCLA neuroscientists use weak electrical signal to stimulate human brain and improve memory
FINDINGSNeuroscientists at the  David Geffen School of Medicine at UCLA have discovered precisely where and how to electrically stimulate the human brain to enhance people’s recollection of distinct memories. People with epilepsy who received low-current electrical pulses showed a significant improvement in their ability to recognize specific faces and ignore simila r ones.Eight of nine patients ’ ability to recognize the faces of specific people improved after receiving electrical pulses to the right side of the brain’s entorhinal area, which is critical to learning and memory. However, electrical stimulation deli...

New therapy spurs nerve fibers to regrow through scar tissue, transmit signals after spinal cord injury in rodents
Neuroscientists at UCLA, Harvard University and the Swiss Federal Institute of Technology have identified a three-pronged treatment that triggers axons — the tiny fibers that link nerve cells and enable them to communicate — to regrow after spinal cord injury in rodents. Not only did the axons grow through scars, they could also transmit signals across the damaged tissue.If researchers can produce similar results in human studies,  the findings could lead to a therapy to regrow axon connections in  people living with spinal cord injury, potentially restoring function. Nature publishes the research in its Aug. 29 onl...
