-As stated repeatedly, this is not an argument. I don’t believe that it proves anything regarding the question currently under discussion.

That said, biofeedback has primarily been tested as a means of treating hypertension. But the effect itself is not limited to such a scope. The brain can also make the heart speed up (not just slow down). And this is just the conscious portion of the brain. The heart itself is regulated by the ANS – with primary control factors being located in the brainstem. (Apologies to the general group about the neurology tangent)
