It produces several relevant messenger substances such as dopamine, oxytocin, glycine, and adrenocorticotropic hormone (ACTH). In fact, through electrical stimulation, during the experiment, they were able to see how increasing motor excitability increased the tendency to follow other people’s yawning.
