A little brain boost is something we could all use now and then. A new option may be on the horizon. Researchers at the National Institute for Neurological Disorders and Stroke, in Bethesda, MD, are studying how applying gentle electrical current to the scalp can improve learning.

A little brain boost is something we could all use now and then. A new option may be on the horizon. Researchers at the National Institute for Neurological Disorders and Stroke, in Bethesda, MD, are studying how applying gentle electrical current to the scalp can improve learning.
-
a stream of current can improve motor function, verbal fluency, and even language learning.
-
The device is simple: a nine-volt battery that's been approved by the Food and Drug Administration for delivering drugs across the skin is connected to large flat sponges that are moistened and then applied to the head. It delivers a gentle 2 to 2.5 milliamps of current spread over a 20 to 50 square millimeter area of the scalp for up to 15 minutes. Little of that current actually reaches the brain--about half is shunted away from the target area, and the other half quickly dissipates as it gets farther from the scalp.
-
researchers found that direct current stimulation could improve memory in participants asked to learn and then recall a list of 12 words.
-
the learning curve for those working without the device quickly caught up to the zapped learners.
