The researchers found that the tissue made normal connections with surrounding nerves and muscle tissues in the mice, and those connections allowed the tissue to function normally. (scientificamerican.com)
On the other hand, mouse pups that did not receive VPA showed normal connections in their developing cerebral cortex. (techtimes.com)
Obviously, researchers would love to be able to replace all the lost neurons and axons and restore normal connections in a damaged spinal cord. (cvm.ncsu.edu)
