Brain to brain technology on rats

Two rats are trained to press a lever when a light indicator is on, receiving water as a reward. Their brains are connected using microelectrodes, allowing them to be separated by large distances. The encoder rat sees a light and presses a lever, sending a signal to the decoder rat. If the decoder rat presses the correct lever, both receive water. If incorrect, the encoder rat's brain signal strengthens.

What action do the rats perform to receive a sip of water?

• Press a lever when the light is off

• Press a lever when the light is on

• Run in a wheel

• Jump over a hurdle

How are the rats' brains connected?

• Using wireless signals

• Through a shared water source

• With microelectrodes

• By a physical cable

What happens when the encoder rat sees a light signal?

• It runs in circles

• It jumps over a barrier

• It ignores the signal

• It pushes the corresponding lever

What reward does the encoder rat receive if the decoder rat presses the correct lever?

• A piece of cheese

• A second sip of water

• A new toy

• A pat on the back

What occurs if the decoder rat presses the wrong lever?

• The encoder rat receives a second sip of water

• The encoder rat's brain signal weakens

• The encoder rat's brain signal becomes stronger

• The decoder rat receives a punishment
