In young rats, researchers find a reaction to spinal cord injury that speeds recovery
...rvous system uses a two-way transmission system to communicate the electrical impulses that lead to muscle movement and the perception of sensation. In humans, hundreds of thousands of nerve fibers (axons), which can be several feet in length, run through the spinal cord like a two-lane road. Half of these axons...Newts which regrow their hearts

An enzyme of this nature - focal adhesion kinase -, which plays a part in the transmission of signals in the cells, is phosphorylated in the transp......ly in the brain where it is used by nerve cells to communicate with each other. So, whilst it can be poisonous, the body also uses it beneficially as an internal signal."

In the new findings, scientists identified more than 175,000 gene tags useful for understanding brain functions, increasing by more than 100 times the amount of genomic information available for...Scientists uncover potential key to brain blood-flow disorders
