High tech: please tell me about the principle and knowledge of remote control of human mind by computer

I believe you are seeing something similar in a book or movie or TV show. In reality what is placed inside the body would not be some isolated substance (like a pill) but a tiny man-made complex device.

1. Currently in humans or other animals in the subcutaneous or visceral implantation of remote control devices has been feasible, mainly using radio remote control technology, computer operation can achieve the effect of: remote sensing implanted where the location of the person (tracking technology), sound recording (eavesdropping, etc.), the body's temperature and pulse and other conditions (diagnostic monitoring), the release of long-lasting drugs (control of medical care), miniature explosive devices (remote cutting). Explosive devices (remote control cutting), interference with bodily functions (human muscle control) and so on.

2. The above body function interference refers to: the implanted person, with or without his knowledge, placed in his subcutaneous, muscle, viscera, blood vessels, and the brain of the miniature therapeutic drug slow-release device (medical treatment) or controlled drug delivery device (suicide or self-mutilation), or brainwave interference device (simple behavioral control), etc.

3.

3. This kind of body function control or interference, at present, generally can only carry out simple control of human behavior and life, but it is impossible to carry out deep spiritual thought or behavioral manipulation, such as immediate learning of a more complex skills operation, instantaneous large-scale emotional changes. And the controlled person's nerves and body damage, is completely possible, is in the human body's blood vessels or muscles, through the implanted micro-remote control device (currently can be such a device to do only as small as a green bean) to release the control of the drug, and then achieve temporary or longer control purposes (such as mental disorders, limb loss of control, etc.).

4. Now this kind of human remote control technology is still rarely used, mainly to control the effect and time of the mastery of the need to be very high requirements, and the general public is rarely used (mainly in the medical). The main technical means of control is radio (electromagnetic wave) technology, simply put, like the control of toy remote control cars, forward and backward (open and close), left and right direction (the size of the amount of energy) on the line.

Such as science fiction films in the human deep spiritual and behavioral control is not yet practical applications, as to whether someone is conducting this research, that is, belongs to the absolute confidentiality! Oh, don't bother prying...
