Trans-Cranial Direct Current Stimulation (Tdcs) – The Future Of Cognitive Enhancement?

tDCS – Transcranial direct current stimulation; involves the application of a very mild current for 20 minutes to the frontal lobes of the brain, through electrodes placed on the skin. Much to my surprise, this extremely simple and non-invasive technique is proving to have lasting effects on learning and cognition – in some instances, lasting as long as 5 hours after the treatment. The results are quite impressive and the data thus far seems consistent. The author of a recent study at Vanderbilt University states, “…when we up-regulate that process, we can make you more cautious, less error-prone, more adaptable to new or changing situations — which is pretty extraordinary.”
