Blood Work: Scientists Uncover Surprising New Tools to Rejuvenate the Brain

Tulips blooming in the California sun

Scientists used to believe that our neurologic fate was sealed at birth with a single, lifetime allotment of brain cells.

The thinking went – not so very long ago – that little by little, with the bumps of age and lifestyle, this initial stash of neurons died, taking our brain function along with them. Yet, strange as it may sound, canaries, video games, and young blood are finally putting that punishing prospect to rest. Studies involving bird song, gaming, and the rejuvenating factors of young blood have shown not only that neurons can be generated throughout adulthood, but also that the maddening aspects of aging, such as memory loss and slower processing speed, can be partially reversed.
