Guest yikes Posted June 19, 2011 Share Posted June 19, 2011 idm as fuck-√ scary orwellian implications-√ just think of the possibilities 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. In a scene right out of a George Orwell novel, a team of scientists working in the fields of “neural engineering” and “Biomimetic MicroElectronic Systems” have successfully created a chip that controls the brain and can be used as a storage device for long-term memories. In studies the scientists have been able to record, download and transfer memories into other hosts with the same chip implanted. The advancement in technology brings the world one step closer to a global police state and the reality of absolute mind control. More terrifying is the potential for implementation of what was only a science fiction fantasy – the “Thought Police” – where the government reads people’s memories and thoughts and can then rehabilitate them through torture before they ever even commit a crime based on a statistical computer analysis showing people with certain types of thoughts are likely to commit a certain type of crime in the future. We already pre-emptively invade nations and torture alleged terrorist suspects with absolutely no due process of law, so the idea of pre-emptively torturing a terrorist suspect beforehand to prevent them from committing an act of terrorism in the future really isn’t that far fetched of an idea. Perhaps a less sensational example than those I just depicted from Orwell’s famous dystopian novels would be using the technology as it is depicted the modern day Matrix movies, in which computer programs are uploaded into people’s brains allowing them to instantly learn how to perform a wide variety of tasks. That is exactly the example that Smart Planet uses in their write-up on the USC press release. The Matrix reality: Scientists successfully implant artificial memory system It seems the sci-fi industry has done it again. Predictions made in novels like Johnny Mnemonic and Neuromancer back in the 1980s of neural implants linking our brains to machines have become a reality. Back then it seemed unthinkable that we’d ever have megabytes stashed in our brain as Keanu Reeves’ character Johnny Mnemonic did in the movie based on William Gibson’s novel. Or that The Matrix character Neo could have martial arts abilities uploaded to his brain, making famous the line, “I know Kung Fu.” (Why Keanu Reeves became the poster boy of sci-fi movies, I’ll never know.) But today we have macaque monkeys that can control a robotic arm with thoughts alone. We have paraplegics given the ability to control computer cursors and wheelchairs with their brain waves. Of course this is about the brain controlling a device. But what about the other direction where we might have a device amplifying the brain? While the cochlear implant might be the best known device of this sort, scientists have been working on brain implants with the goal to enhance memory. This sort of breakthrough could lead to building a neural prosthesis to help stroke victims or those with Alzheimer’s. Or at the extreme, think uploading Kung Fu talent into our brains. Decade-long work led by Theodore Berger at University of Southern California, in collaboration with teams from Wake Forest University, has provided a big step in the direction of artificial working memory. Their study is finally published today in the Journal of Neural Engineering. A microchip implanted into a rat’s brain can take on the role of the hippocampus—the area responsible for long-term memories—encoding memory brain wave patterns and then sending that same electrical pattern of signals through the brain. Back in 2008, Berger told Scientific American, that if the brain patterns for the sentence, “See Spot Run,” or even an entire book could be deciphered, then we might make uploading instructions to the brain a reality. “The kinds of examples [the U.S. Department of Defense] likes to typically use are coded information for flying an F-15,” Berger is quoted in the article as saying. [...] In this current study the scientists had rats learn a task, pressing one of two levers to receive a sip of water. Scientists inserted a microchip into the rat’s brain, with wires threaded into their hippocampus. Here the chip recorded electrical patterns from two specific areas labeled CA1 and CA3 that work together to learn and store the new information of which lever to press to get water. Scientists then shut down CA1 with a drug. And built an artificial hippocampal part that could duplicate such electrical patterns between CA1 and CA3, and inserted it into the rat’s brain. With this artificial part, rats whose CA1 had been pharmacologically blocked, could still encode long-term memories. And in those rats who had normally functioning CA1, the new implant extended the length of time a memory could be held. [...] Source: Smart Planet USC: Restoring Memory, Repairing Damaged Brains Biomedical engineers analyze—and duplicate—the neural mechanism of learning in rats LOS ANGELES, June 17, 2011 /PRNewswire-USNewswire/ Scientists have developed a way to turn memories on and off—literally with the flip of a switch. (Image Information)For stroke or Alzheimer's victims, the promise of Dr. Theodore Berger's recent breakthrough is enormous: imagine a prosthetic chip inserted in the brain that imitates the function of a brain's damaged hippocampus (the region associated with long term memory). 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. (PRNewsFoto/USC Viterbi School of Engineering) 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. Marmarelis and Research Assistant Professor Dong Song, and from Wake Forest, Associate Professor Robert E. Hampson and Post-Doctoral Fellow Anushka Goonawardena. Berger, who holds the David Packard Chair in Engineering, is the Director of the USC Center for Neural Engineering, Associate Director of the National Science Foundation Biomimetic MicroElectronic Systems Engineering Research Center, and a Fellow of the IEEE, the AAAS, and the AIMBE.

delet... Posted June 19, 2011 Share Posted June 19, 2011 Also, lol @ "megabytes stashed in our brain". This guy seems the wrong person to be reporting on the work done there. I'd like to see proper academic criticism of the claims made or conclusions drawn. It is my understanding that the development of the brain in an unique being is a haphazard process, things beyond basic nature, are learnt through trial and error. So what they're trying to do in transferring memories may be like speaking broken japanese sentences to a kalahari bushman, or more succinctly, like plugging a nintendo video out into an android phone, completely uninterpretable. (probably, but that's why we need the critique) Link to comment Share on other sites More sharing options...

lumpenprol Posted June 19, 2011 Share Posted June 19, 2011 Yeah I stopped reading somewhere in the first paragraph. Don't see why the guy is so worried as if this is actual reporting and not a hoax, his brain clearly is in dire need of an upgrade. Link to comment Share on other sites More sharing options...
