A small handful of doctors in China are using a highly controversial procedure to rid people of drug addiction by destroying a part of patients' brains. The procedure involves drilling small holes into the skulls of patients and inserting long electrodes that destroy a part of the brain called the nucleus accumbens. This area, often referred to as the "pleasure center" of the brain, is the major nucleus of the brain's reward circuit. Is it worth being cured of addiction if, losing the addiction, we also lose part of who we are?
BTW, this method to cure addiction was developed by soviet pseudo-scientist http://en.wikipedia.org/wiki/Natalia_Bekhtereva who was also know for her advertisement of various mages and psychics.
