The answer is a. MRI “monkey see monkey do” tests on monkeys performing tasks.
Mirror neuron is a neuron that fires not only when an animal performs an action, but also when someone else perform the same action. It was discovered in experiments with macaque monkeys using an MRI (magnetic resonance imaging). In the experiment, if a monkey rips a piece of paper, mirror neuron is activated, as well as it is activated when the monkey sees or hears that someone else rip the piece of paper.
