After a simple explanation, complete with pictured light bulb inside a head, of how messages in the form of electrical signals travel along nerve cell branches to ""the special part of the brain that takes care of that problem,"" the Pereras state that the process of storing information--in ""a place in your brain"" we call memory--is part of what we call learning. Many scientists, they add, believe that thinking is the rearranging of this stored information, and, possibly, the more you use and exercise the pathways involved, the easier thinking becomes. ""Scientists are not sure about this."" Not much here to store, but it might establish some new connections.
