A future of your emotional well being might depend on something called tDCS or transcranial direct current stimulation. Used as a potential means to address neuropsychiatric disorders, including depression, transcranial direct current stimulation is just that, stimulation of the brain through a low-level direct current. Basically, zapping your brain! You read it right! But I’d have to stop you here before you go on with the idea of electroshocks and twitching.

Has science finally found a way to make us smarter and still keep our health? Well, some say it has!

Living in such a cutthroat world, where a slight edge in memory and focus can mean a huge difference, as we are constantly on the lookout for new ways to make us smarter, more motivated and driven. This is how we came to something called tDCS, a method scientists think will help us have that extra-fast brain. So what is tDCS stand for...?

tDCS has taken the world of neuroscience by storm. Scientists have started experimenting with the notion that a low electrical current passing through the skull can enhance the cognitive powers of an individual. Though the idea of zapping the brain to help individuals is not a new one (the experiments have been conducted for a couple of decades now), the notion that using tDCS for healthy individuals to enhance their working memory, heighten concentration and improve their cognitive powers is a completely new one. It has made such hype in the world of science that many scientists have taken upon themselves to prove that it works.

Your own DIY tDCS device? Many of our readers have told us that they’ve found resources online with the electrical schematics to build their own transcranial direct current stimulation, tDCS device for around $20-$25 in materials. Ultimately, they ask us if we would recommend this method to get started on the cheap..

With the tDCS anode placed on the back upper head and the tDCS cathode on the left side at the same position, this montage increases the sense of empathy that the user has for other people. This montage is in perfect sync with Loving Kindness Meditation, aka Metta, the aim of which is to send positive thoughts and vibrations towards three people that the individual practicing meditation has contact:  a close person, a neutral one and one that they have had a conflict with.

These tDCS montages are just an example of...
