Baro receptor in brain stimulated to protect heart from Over stimulation of NE. Reflex action activate Parasympathetic neuron (M2) agonist at heart which reduce heart rate producing reflex bradycardia.
Should have used Phenylephrine as an example instead of Norepinephrine. Since it is alpha 1 and alpha 2 stimulation without beta receptor stimulation, the reflex bradycardia is significant. With Norepinephrine, the beta 1 activity usually negates the bradycardia or at least minimizes it.
@@NonstopNeuron I get what you’re saying but I disagree. If you’re trying to explain reflex bradycardia then phenylephrine does so better. My opinion. But appreciate the content.

But that will not explain how norepinephrine produces reflex bradycardia in spite of having β1 action. So, taking norepinephrine addresses both.
