It had to depend on the visual information from the brain of the first rat to know which lever to push to get the reward.<\/p>\n<p>It gets better.\u00a0 The first rat didn&#8217;t get a reward if the 2nd rat pushed the wrong lever.\u00a0 The communication became two way.\u00a0 The first rat modified it&#8217;s behaviors and brain function to help the 2nd rat get the right lever.<\/p>\n<p>Now, neither of the rats was saying, &#8220;I&#8217;m going to modify my brain function to get that treat.&#8221;\u00a0 What probably happened was the 1st rat was expecting a reward.\u00a0 When the reward didn&#8217;t appear, it repeated the behavior, maybe in a slightly different way.\u00a0 Like a small child who almost got something right, it tried harder.\u00a0 My speculation would be that more focus on the task would result in a &#8216;cleaner&#8217; mind state sent to the receiving rat.<\/p>\n<p>It&#8217;s like humans, we do some things so often, we don&#8217;t even think about it&#8230; until we&#8217;re forced to.\u00a0 For example, going to pee is easy.\u00a0 Going to pee with a broken wrist requires some thinking and focus.<\/p>\n<p>The second experiment involved rats using their whiskers to measure the size of an opening.\u00a0 That information was then transmitted from a rat in Brazil to a rat in North Carolina who performed a task based on the size of the opening.<\/p>\n<p>One, very fascinating thing, that the researchers found was that the receiving rat&#8217;s brain actually changed.\u00a0 The 2nd rat&#8217;s brain actually created a second &#8220;whisker pattern&#8221; in its brain that responded to the 1st rat and not its own whiskers.<\/p>\n<p>Basically, your brain has a representation of you in it.\u00a0 That representation is linked to all the sensory nerves in your body.\u00a0 That&#8217;s how you know when someone pokes you in the leg or in the hand.\u00a0 Rats&#8217; whiskers are connected to sensory nerves and, some time ago, researchers had mapped the whisker pattern in the rats brain.<\/p>\n<p>But the rat in North Carolina built (for lack of a better term) a second mental map for a set of whiskers.\u00a0 Only it was the set of whiskers of a rat on another continent connected to it by the internet.\u00a0 Yes, the brain maps were sent via the internet.<\/p>\n<p>The rat&#8217;s brain was plastic enough (a technical term meaning that the brain can change) to accommodate a complete second set of whiskers.<\/p>\n<p>These experiments were done with only a few thousand neurons mapped in the brain.\u00a0 The researchers are hoping for an order of magnitude increase in the amount of mapped neurons in the next few years.<\/p>\n<p>The researchers are also considering whether this could develop into an organic computer system.\u00a0 There&#8217;s nothing in the knowledge or technology that would prevent multiple animals from being linked in an organic social computing network.<\/p>\n<p>The researchers are looking at this to help paralyzed people learn to walk or control exoskeltons.<\/p>\n<p>Personally, I can&#8217;t wait to learn Kung Fu via download.\u00a0 The only problem I see is some one hacking into a system like this and just programming humans to be smart bombs or religious zealots.\u00a0 The science fiction novel<a href=\"http:\/\/www.amazon.com\/Helm-Steven-Gould\/dp\/0812571355\/ref=sr_1_1?ie=UTF8&amp;qid=1362161640&amp;sr=8-1&amp;keywords=Helm\"> Helm<\/a>, by Steven Gould (not THAT Stephen Gould) talks about some of this kind of technology and uses for bad and good.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>OK, my mind is officially blown.\u00a0 Science is just so freaking cool.
