3.2 First Brainets
  • Humans and animals need circuits of neurons, not individual neurons, to do computations and have multiple outputs.

    • At any moment in time, the brain can pull from the billions of neurons, a subset than can produce a particular behavio.
    • If some neurons die, there are new combinations of neurons that can produce behaviors.
  • Professor Nicolelis created a mouse-to-mouse brainet.

    • To test how multiple areas of the brain come together to synchronize and to generate a common function, Nicolelis created brain-to-brain interactions.
    • Tests were conducted by linking brains in rats.
    • Nicolelis recorded the brain activity of a rat making a decision (encoder) and sent the electrical activity to a second rat (decoder).
    • The decoder mouse had to choose between left and right to get a reward, but only the encoder mouse knew which side was correct.
    • The rats were able to succeed 70% of the tim.
  • Brainet experiments with three monkeys showed they were able to collaborate in a video game together successfully 70% of the time.
