You Can Grow Brain Cells Through Exercise?

Researchers have discovered that aerobic exercise may increase neurogenesis. 

 Based on the results, rats that were put on a treadmill grew more brain cells than rats that didn't. 

Resistance training seemed to have no effect.

 This is significant, because the neuron reserve of the hippocampus can be increased, thus preconditions for learning for humans could be improved simply through aerobic exercise.
