Astrocytes shown to regulate signal speeds of neurons.

The world’s greatest supercomputer, also known as the human brain is composed of neurons with tail-like extensions known as axons.  Axons are wrapped in layers of myelin, serving as insulation to increase the speed of signals relayed by neurons. Gaps between segments of myelin are called nodes of Ranvier, with the number and width of these gaps known to regulate
