What Is Brain Hacking?

Depression is among most common illnesses worldwide today. As the growing population of an estimated 350 million people suffer from it, many of them are struggling to find a simple yet effective solution to their problem. Recently, an idea of using electrical current to stimulate the brain has emerged on a popular social news and discussion website.
Transcranial direct current stimulation (tDCS), now popularly called “brain hacking”, is said to not only help those battling depression, epilepsy and other similar conditions but also to improve concentration, memory and mental abilities of healthy individuals. The process is quite simple, it uses two electrodes, cathode and anode, which are put on the skin on certain positions on the head. The current used is a very low-voltage direct current. Those behind this method claim that the current enters the brain through the skull and causes neurons to change their firing rate, which then leads to beneficial effects. If proven right, the possibilities of brain hacking would be
For example, stroke patients, using this method, would be able to regain partial function of their damaged brain area. However, “brain hacking” remains FDA-unapproved as very few research exists on this subject. Also, scientists are split on this question. The
