Scientists Successfully Implant Chip That Controls The Brain Allowing Thoughts, Memory And Behavior To Be Transferred From One Brain To Another
Scientists working at the University of Southern California, home of the Department of Homeland Security’s National Center for Risk and Economic Analysis of Terrorism Events, have created an artificial memory system that allows thoughts, memories and learned behavior to be transferred from one brain to another.
The current successful laboratory tests on rats, restoring long term memory at the flick of a switch, will next be duplicated in primates (monkeys) and eventually humans. But there a couple of hundred thousand of humans that very much realized that there is very little use testing A.I. on monkeys or any animal but a Human Being concerning this particular industry. Those that not only claim but often have verifying evidence they have been used for Human Experimentation for rather obvious reasons those agencies and laboratories that 'are allowed ' to "practice" A.I. on people ,without their consent keep these studies guised and guarded and may do so because their are indeed implications concerning this technology that pertain to Homeland Security. Those chosen to be literally made "lab rats" are called Targeted Individuals.
Using an electronic system that duplicates the neural signals associated with memory, they managed to replicate the brain function in rats associated with long-term learned behavior, even when the rats had been drugged to forget.“Flip the switch on, and the rats remember. Flip it off, and the rats forget,” said Theodore Berger of the USC Viterbi School of Engineering’s Department of Biomedical Engineering.Berger is the lead author of an article that will be published in the Journal of Neural Engineering. His team worked with scientists from Wake Forest University in the study, building on recent advances in our understanding of the brain area known as the hippocampus and its role in learning.In the experiment, the researchers had rats learn a task, pressing one lever rather than another to receive a reward. Using embedded electrical probes, the experimental research team, led by Sam A. Deadwyler of the Wake Forest Department of Physiology and Pharmacology, recorded changes in the rat’s brain activity between the two major internal divisions of the hippocampus, known as subregions CA3 and CA1. During the learning process, the hippocampus converts short-term memory into long-term memory, the researchers prior work has shown.“No hippocampus,” says Berger, “no long-term memory, but still short-term memory.” CA3 and CA1 interact to create long-term memory, prior research has shown.In a dramatic demonstration, the experimenters blocked the normal neural interactions between the two areas using pharmacological agents. The previously trained rats then no longer displayed the long-term learned behavior.“The rats still showed that they knew ‘when you press left first, then press right next time, and vice-versa,’” Berger said. “And they still knew in general to press levers for water, but they could only remember whether they had pressed left or right for 5-10 seconds.”Using a model created by the prosthetics research team led by Berger, the teams then went further and developed an artificial hippocampal system that could duplicate the pattern of interaction between CA3-CA1 interactions.Long-term memory capability returned to the pharmacologically blocked rats when the team activated the electronic device programmed to duplicate the memory-encoding function.In addition, the researchers went on to show that if a prosthetic device and its associated electrodes were implanted in animals with a normal, functioning hippocampus, the device could actually strengthen the memory being generated internally in the brain and enhance the memory capability of normal rats.“These integrated experimental modeling studies show for the first time that with sufficient information about the neural coding of memories, a neural prosthesis capable of real-time identification and manipulation of the encoding process can restore and even enhance cognitive mnemonic processes,” says the paper.Next steps, according to Berger and Deadwyler, will be attempts to duplicate the rat results in primates (monkeys), with the aim of eventually creating prostheses that might help the human victims of Alzheimer’s disease, stroke or injury recover function.The paper is entitled “A Cortical Neural Prosthesis for Restoring and Enhancing Memory.” Besides Deadwyler and Berger, the other authors are, from USC, BME Professor Vasilis Z.
