Neurons are cells found in the nervous system, which transmit information either by electrical or chemical signaling. Information travels out of a neuron down a projection called an axon to the next neuron. If the axon is wrapped in a material called myelin, then information can travel faster. This picture shows the neuronal nuclei (red) within the mouse cerebral cortex, along with a meshwork of axons ensheathed in myelin (green) surrounding the neurons. All cell nuclei, regardless of cell type, are stained blue.
