Resumen de Telepathic animals solve task as one
The world's first brain-to-brain link has given rats and monkeys the power to communicate by thought alone. Although monkeys have used brain-to-machine interfaces to control robots, Miguel Nicolelis and his team created the first direct connection between two brains. His team initially trained rats to press one of two levers when an LED above that lever was lit, in order to receive a reward. The rats were then split into two groups: encoders and decoders. Each encoder rat had an array of microelectrodes implanted into its primary motor cortex, a brain region that processes movement. The researchers used the implant to record neuronal activity just before the rat makes a decision in the lever task. They found that pressing the left lever produced a different pattern of activity from pressing the right, regardless of which was the correct action.
