New neurons in the brain discovered

In spite of the long belief that the individual brain does not develop new neurons as we get old, recent analyses in the last years have determined that it does (our brains are shriking over the generations, however.)

Just men of science were not certain what the new neurons do.

A fresh study indicates they clear off the leftovers of old memories to create some space for new ones. The brain's hippocampus works like an inbox for memories, which then must be shuttled elsewhere for lasting storage. One function of new neurons is to clean out the inbox once memories are filed.

A lot explore in this field is needed to verify the results.
