Remember the Mythbusters episode where they seemingly claimed to have debunked the psionic helmet? Well, now mainstream science says that magnets may help make the brain grow stronger. While the exact mechanism remains unknown, the boys in white lab coats have determined that magnets can induce electric fields in the brain tissue which, in turn, activate or deactivate groups of neurons. They theorized that this process aids learning and memory by strengthening brain circuits through a process called long-term potentiation (LTP). Emphasis on LONG-TERM. Something that a Mythbusters episode is NOT!
