Coolt! Det här kanske är mindre coolt: Scientists Successfully Implant Chip That Controls The Brain; Allowing Thoughts, Memory And Behavior To Be Transferred From One Brain To Another http://www.activistpost.com/2011/06/scientists-successfully-implant-chip.html
Citat: 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.
Ja, det där känns lite oroväckande faktiskt. Det är nog lite emot alltets gång att leka gud sådär, teknik är inte alltid bra. Dessutom finns det nog någon hake i det där, att gå förbi inlärningsprocessen på det där sättet bara måste ha negativa effekter. Man kan kanske också tänka sig att tekniken kan ha en del mer ljusskygga användningsområden?
Coolt!
