Researchers show that animals can collaborate via a brain-to-brain interface.
Pairs of rats can communicate through brain chips and collaborate to perform a task, report researchers in today’s Scientific Reports. Brain activity recorded in one rat was translated into a pattern of electrical pulses that were then transmitted to another rat that had been trained to push a particular lever in response to one of two patterns of electrical stimulation in its brain. The rats also worked together, say the researchers. If the second rat chose the wrong lever, then the first rat would change its brain function and behavior in the next trial so that the receiving rodent was more likely to get it right, claim the scientists.
