Frightening ?
1. One rat is designated the “encoder”, who will receive a visual clue, the other is the “decoder”, who will not.
2. A light is switched on in the trained, encoder rat’s cage above one of two levers which will release a reward if pressed.
3. The encoder rat sees the light and presses a lever to receive a reward. As it does so, the brain signal is sent to the decoder rat’s brain.
4. The decoder rat interprets the brain signal, chooses the correct lever and gets a reward. If the decoder rat gets it right, the encoder rat gets an extra reward.
