The human brain constantly adapts in response to experiences, forming new connections between neurons and reorganizing existing ones. The brain's ability to adapt in response to experiences is known as neuroplasticity.
Consider two seemingly unrelated medical puzzles. First: Every day, our bodies produce hundreds of billions of new cells, many of which are mutated. If cancer arises from cellular mutation, why don't we all have the disease ...
