If you could stretch out all of a human’s blood vessels, they would be about 60,000 miles long. The brain’s precisely coordinated action relies on a dense network of fibers capable of rapidly transmitting information, both locally (to adjacent neurons whose separation can be measured in microns) and to distant locations removed by many centimeters from one another. The exception to this is the vagus nerve, which is the longest cranial nerve. Some methods can include but aren’t limited to supplementation of growth-promoting cells, specific growth factors, or even stem cells to promote regeneration or repair of nerve tissue.
