Skull electrodes give memory a boost

University of Sydney researchers have developed the first non-invasive method of stimulating the brain that can boost visual memory. It uses transcranial direct current stimulation (tDCS), in which weak electrical currents are applied to the scalp using electrodes.

The method can temporarily increase or decrease activity in the anterior temporal lobe (ATL), an area near the temple, and has already been shown to boost verbal and motor skills in volunteers.
