it has something do to with the regulation of dopamine and 5-TH? serotonin.
I think dopamine is the reward neurotransmmitter. Lack of it can cause cardiovascualar problems, vasoconstriction, and migraines.
the pacemaker seeks to regulate dopamine (reward nuerotransmitter) , and serotonin (mood nuerotransmitter)
