[quote] One rat was designated as the "encoder". Once this rat pressed the correct lever, its brain activity was delivered as electrical stimulation into the brain of the second rat - designated the "decoder". The decoder rat had the same types of levers in its chamber, but it did not receive any visual cue indicating which lever it should press to obtain a reward. In order to receive the reward, the decoder rat would have to rely on the cue transmitted from the encoder via the brain-to-brain interface. "There is a moment in time when... it clicks. Suddenly the [decoder] animal realises: 'Oops! The solution is in my head. It's coming to me' and he gets it right." There was also a feedback system, denying the encoder rat an extra reward if the decoder rat did not press the correct lever. The encoder rat's brain signals then became clearer, giving the decoder a greater chance of interpreting the message correctly, Prof Nicolelis noted. "We will have a way to exchange information across millions of people without using keyboards or voice recognition devices or the type of interfaces that we normally use today," he said. "I truly believe that in a few decades… we will know what it is to communicate in that way."[/quote] So basically like the Protheans in Mass Effect which can share idea's instantly can be replicated for Humans in reality, basically it could stop people being complete and utter idiots. Maybe education would vanish and you learn everything you know by having somebody transfer their knowledge to you, perhaps even the start of telepathy. This is incredible.
