According to the journal Nature, the research agency DARPA has funded the development of a system for automatic control of a person’s mood, which, in real time, scans brain activity and, if necessary, eliminates “unwanted failures” that can cause depressive conditions.
The device itself is not inherently unthinkable. It is a chip for deep stimulation of the brain. Such intracranial neuroimplants are already used to treat disorders of motor activity, restoration of lost functions due to stroke and Parkinson’s disease. But any attempts to influence not the physical, but the emotional component previously ended unsuccessfully.
The new type of neyroimplants most of the time is in a “sleeping” mode and turns on only as needed, when “the mood goes beyond the permissible limits.” As part of the training, experts fixed the activity of the brain and the mood of the experimental subjects in order to compare the change in brain activity with a deterioration in mood. Then the data was introduced into the system, which was adjusted in such a way that the stimulation of brain regions responsible for the mood would begin only when it went beyond the permissible boundaries, in other words, it became bad. That is, a small disorder does not cause activation of the chip, in contrast to a state close to depression.
According to the chip developers, a personalized mood management system can help patients with severe behavioral disorders, as well as soldiers to whom neuroimplants can help cope with the effects of stress during hostilities and post-traumatic syndrome. Moreover, in the future DARPA plans to develop similar devices that do not require implantation in the skull.
