Following up on Vincent Clark at UNM, working on the IARPA-funded SHARP project.

The current researchers use has a few effects including increasing chemicals in the brain that help humans encode memories. As those chemicals increase, people find it easier to learn new things. Another effect involves the applied current, which seems to alter attention so that people can attend to what they’re doing better; they can pay more attention to the task at hand.

When the researchers gave people tDCS, their score went up faster. An examination of the difference before and after shows a score that goes up about 14 percent without tDCS. With full tDCS, the score goes up about 27 percent. If they wait an hour and test again, and compare no tDCS with full tDCS, it goes up even more.
