What new experimental method was used after the team of scientists had the hypothesis about mirror neurons?
a. mri “monkey see monkey do” tests on monkeys performing tasks
b. double blind placebo experiments
c. mri “monkey see monkey do” tests on humans performing tasks
d. placebo experiments

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.
