Rats Communicate Through Brain Chips: The researchers also demonstrated the brain-to-brain communication with whisker stimulation in the first rat. Like a cat, rats use their whiskers to determine how wide an opening is, and the rodents can be trained to turn their head to the left or right depending on whether a hole in their cage is narrow. Similar to the first experiment, the brain activity of the first rat was translated into a particular pattern of pulses sent to the second rat, which had been trained to poke its head left in response to electrical pulses, and right in the absence of pulses. With these tests, the second rat chose the correct side about 62 percent of the time.
