These are chemicals which enable information to move around the brain and the body, by transferring signals across synapses (connections between neurons). They can either trigger a signal (excitatory), for example dopamine, or stop a signal (inhibitory), for example serotonin. They are important for background activities like breathing and digestion, and they can also affect mood and concentration.
