Science fiction author Philip K. Dick's stories have been used in more movies than those of any other writer: Bladerunner, Total Recall and Paycheck are all derived from his stories. Scientists are now taking a page out of his books. In his 1964 novel The Three Stigmata of Palmer Eldritch, people could actually get more brains if they wanted to be smarter. A procedure called E Therapy was performed to increase the size of their brains:
Some day soon, you may get your wish to be brainier. According to researchers at MIT, a single gene and its growth-promoting protein (CPG15) may be used to develop therapies for renewing damaged or diseased brain tissue.
Over-expressing CPG-15 in rats gives them bigger brains; these enlarged brains have grooves and furrows like evolved mammalian brains with larger surface areas.
In another recent study performed at Harvard, the beta-catenin gene in selected mice was engineered to exhibit increased activity; the mouse brains grew to almost double the usual size. The cerebral cortex, seat of intelligence and language, became more human like.
