Brain Health and Willful Consciousness
MORE Credit: Shutterstock We may go to sleep at night, but our brains don’t. Instead, they spend those quiet hours tidying up, and one of their chores is to lug memories into long-term storage boxes . Now, a group of scientists may have found a way to give that memory-storing process a boost, by delivering precisely timed electric zaps to the brain at the exact right moments of sleep. These zaps, the researchers found, can improve memory . And to make matters even more interesting, the team of researchers was funded by the Defense Advanced Research Projects Agency (DARPA), the U.S. agency tasked with developing technology for the military. They reported their findings July 23 in The Journal of Neuroscience . If the findings are confirmed with additional research, the brain zaps could one day be used to help students study for a big exam, assist people at work or even treat patients with memory impairments , including those who experienced a traumatic brain injury in the military, said senior study author Praveen Pilly, a senior scientist at HRL Laboratories, a research facility focused on advancing technology. [ 5 Surprising Sleep Discoveries ] The study involved 16 healthy adults from the Albuquerque, New Mexico, area. The first night, no experiments were run; instead, it was simply an opportunity for the participants to get accustomed to spending the night in the sleep lab while wearing the lumpy stimulation cap designed to deliver the tiny zaps to their brains. Indeed, when the researchers started the experiment, "our biggest worry [was] whether our subjects [could] sleep with all those wires," Pilly told Live Science. The next night, the experiment began: Before the participants fell asleep, they were shown war-like scenes and were asked to spot the location of certain targets, such as […]
