DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Active lifestyle influences regenerative capacity of neurons after spinal cord injury

The influence of an active lifestyle on the regenerative capacity of the peripheral nervous system, that is, the set of cranial and spinal nerves that control motor and sensory functions, is described here for the first time, explains Ángel Barco, who has led the participation of the Institute of Neurosciences UMH-CSIC, in Alicante, in this international study.
