Neurons can be linked together with light Stocktrek Images, Inc./Alamy
A way to link unconnected neurons in the brain and change an organism’s behaviour, dubbed neural engineering, could one day help treat spinal injuries.
There is already a technique for manipulating neurons with light, known as optogenetics, that been used for a variety of purposes, such as controlling the (Caenorhabditis elegans). But using this method in vertebrates, including humans, requires invasive surgical procedures so the light can reach specific brain cells.
