Skull electrodes give memory a boost - New Scientist - New Scientist

Skull electrodes give memory a boost: "The technique uses transcranial direct current stimulation (tDCS), in which weak electrical currents are applied to the scalp using electrodes. ...

Subjects then repeated the experiment 12 times, with one group receiving so-called anodal tDCS (which boosts activity) on their right ATL and cathodal tDCS (which inhibits activity) on their left. A second group received the opposite stimulation and a third group received a placebo treatment, which did not stimulate either side of the brain.

Those in the first group more than doubled their scores after receiving tDCS, experiencing a 110 per cent improvement in visual memory. Participants in the second and third groups showed no overall improvement in performance."
