Basically, two pivotal notions about the nature of the brain have been nullified. __22__ The second is that thebrain steadily loses brain cells after age twenty or so and consequently relentlessly declines in mental capacities.  __23__ But scientists thought older brains lost the capacity to grow, and were fixed and static after puberty. It isnow known that brain cells can sprout new dendrites and new synapses, forming new communication networks at anyage. Thus, although everyone is born with a fixed number of brain cells, that innate figure does not define mentalcapacity. __24__ Brains with fewer cells can have just as much, or more, mental capacity than larger brains, dependingon the lushness of neurons. The idea that a massive and progressive loss of neurons is an inevitable consequence ofaging has also been thoroughly disproved.  According to Russell L. Blaylock at University of Mississippi Medical Center, “The process by which the brain is‘wired’ and even ‘rewired’ is referred to as plasticity. __25__ We now know that even the brains of adults areconstantly changing and being rewired.”
