Neurologists have tested a unique method of brain rejuvenation

A bone marrow transplant taken from a young donor can have an amazing effect on an aging body. The bone marrow of a healthy young mouse was transplanted to old mice. As a result, the cells of old mice were well preserved, and the level of cognitive abilities was increased, "Naked Science" reports. The animals showed an increased level of activity, improved learning ability, as well as had a good spatial and working memory.

This is a valuable discovery, which can give medications for age-related ailments and aging in the future. According to the results of detailed analysis, the owners of young bone marrow have more synapses between neurons (connections, necessary for signal transmission) in the hippocampus (memory center of the brain). At the same time, the total number of neurons did not differ in old individuals and individuals who received young bone marrow.

According to scientists, young bone marrow is associated with reduced activation of microglia – the type of immune cells in the brain. Microglia supports the health of neurons, but in the case of increased activity leads to the breakdown of synapses. The less level of microglia, the more healthy neurons and synapses in the brain.
