How Stem Cell Can Help Rejuvenate an Old Brain


Science Daily shares some really intriguing findings in this piece. It’s called Rejuvenating the Brain With Stem Cells.

In it, scientists reveal some really thought-provoking findings. Here’s one of them:

It is well known that individuals learn to navigate in a new environment in a different way depending on whether they are young or old. When young, the brain can build and remember a cognitive map of the environment but this ability fades away in older brains. As an alternative solution to the problem, older brains without a cognitive map of the environment need to learn the fixed series of turns and twists that are needed to reach a certain destination. While the two strategies may superficially appear similar, only a cognitive map can allow individuals to navigate efficiently when starting from a new location or when in need of reaching a new destination.
