Demyelination -  A cellular response to trauma that destroys myelin, the fatty substance that insulates and protects axons to improve their transmission of electrical impulses. Demyelination impedes or halts that transmission, resulting in a loss of function.
Dorsal Horns (also called posterior horns) -  A pair of projections that form the back “wings” of the butterfly-shaped gray matter in the spinal cord.
Dorsal Root Ganglion (DRG) neurons -  Neurons just outside the spinal cord that receive sensory information from the periphery of the body and transmit it to the brain. These cells readily regenerate their axons after an injury.
Drosophila melanogaster -  A fruit fly often used in genetic studies.
