Other implants, like contraception, addressed biochemistry. Neuronal implants like Berger's black box directly address the control of human behavior. It reduces human brain activity to digital information, suitable for programming. Eventually, these researchers could learn which synaptic patterns correspond to meaningful human events, and the implants they build could interfere with and supplant our thoughts, memories and feelings. Mitochondrial DNA helps regulate cellular metabolic functions.
Cancer is the breakdown of cellular messaging and control.
Implanted identification tags help track wayward pets and, one day, perhaps employees. And silicon neural units like the ones in Berger's USC project will someday replace worn-out patterns of thinking with new and more acceptable patterns of thought. These groups could perhaps respond to particular input-output patterns, catalogued by official agencies or unofficial individuals, overt and covert. Well, yes, the United States government. In fact, they've already done some nifty work with a little help from biochemistry.
