Transcranial Direct Current Stimulation

Transcranial direct current stimulation, or tDCS is a non-invasive way to electrically stimulate the brain. In essence, its connecting a battery to the brain via a wet sponge.

A nine-volt battery 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 millimetre area of the scalp for up to 15 minutes.

Whilst the mechanism behind it are unclear, 'boosting' the electrical power running through the brain by this tiny amount - most of that 2.5 milliamps is dissipated throughout the head, not just the brain - has been shown to temporarily improve memory access and general cognitive ability. It is often used in the treatment of damaged brains.
