The device itself inherently is not something unimaginable. It is a chip for deep brain stimulation. Such intracranial neuroimplant already used for the treatment of impaired motor activity, restore lost function due to stroke and Parkinson's disease. But any attempt to affect on a physical and emotional component earlier it was ended unsuccessfully.
A new kind of neuroimplants most of the time is in "sleep" mode and activated only as needed, when the "mood is out of range". In preparation for the experts recorded brain activity and mood of the subject, to map the changing activity of the brain with deterioration of mood. Then, the data was entered into the system which is adjusted so that the stimulation sites of the brain responsible for mood, would begin only when it is outside the limits, in other words, was bad. That is a small disorder does not cause activation of the chip, in contrast to a state close to depression.
According to developers of the chip, personalized management system mood can help patients with severe behavioral disorders, as well as soldiers who neuroimplant can help to cope with the effects of stress during hostilities and post-traumatic stress disorder. Moreover, in the future, DARPA plans to develop similar devices that do not require implantation in the skull.
