Transcranial Direct Current Stimulation: An Update

It's been a while since I posted a blog article on transcranial direct current stimulation. Probably not an exciting new therapy for psychiatric conditions but a exciting oportunity to study the actions of certain brain parts and a way of influencing these superficial parts of the brain. You can see the procedure in a video here: Video of Transcranial Dirrect Current Stimulation and Efficacy in Cognitive Neurorehabilitation. The first publication on memory and tDCS and it's mechanism of action can be read here: Transcranial Direct Current Stimulation, Brain Boost and Side-Effects. A recent publication shows that Transcranial direct current stimulation (tDCS), .....read more »

What is transcranial direct current stimulation? With tDCS a weak electrical current of 1 or 2 m Ampere is applied to the head with an electrode. The electrode is a non-metalic conductive rubber electrode, covered completely by saline soaked sponges.It is a noninvasive brain stimulation technique that utilizes low amplitude direct currents applied via scalp electrodes to inject currents in the brain and thus modulates the level of excitability. It doesn’t elicit seizures and it doesn’t require anesthesia. For comparison in ECT current of 9 m Ampere is used to elicit seizures during narcosis. Advantages for tDCS above rTMS? In comparison with rTMS, .....read more »

Transcranial direct current stimulation (TDCS) could improve memory in participants asked to learn and then recall a list of 12 words. The effect was significant in the early learning stages: in the first few trials, in which participants were given the same list over and over again, people in the treatment group could remember more words. But the learning curve for those working without the device quickly caught up to the zapped learners.This conclusion of a recent research on TDCS published on Technology Review: Want to Enhance Your Brain Power? At first the encoding of of the words is better .....read more »
