The majority of brain cells aren’t neurons
Did you know that for all the neurons in the brain, there are at least as many glial cells that support and protect these neurons? “These microscopic unsung heroes make sure neurons have a constant supply of nutrients and oxygen, insulate neurons from each other, and even help clean up after neural damage,” says Dr. Wingeier. “They even help optimize communication between neurons.”
Exercise is just as good for your brain as it is for your body
Professional athletes know how important fueling their brain is to ensure they’re able to put maximum effort and energy into their workouts. “This is because of the mental stimulation that comes with exercise, but also because a healthy cardiovascular system means better plumbing for the brain,” says Dr. Wingeier. Especially when you try a new fitness class or regimen for the first time, your brain is working hard at learning the motions and controlling your muscles.
You can “see” through your ears
Neuroplasticity, or the brain’s ability to reorganize and change itself throughout a person’s lifetime, is a truly remarkable thing. One study by the University of Montreal compared the brain activity of individuals who were born blind and those who had normal vision. They found that the part of the brain that’s normally wired to work with our eyes can instead rewire itself to process sound information instead of visual perception. Pretty cool, right?
