Bioseeediback: A Primer for Autonomic Regulation

Mechanisms of Biosubsidback in CAN

Terapeutic effect of bioefediback in CAN is rooted in neuroplasticity and thee central nervous system 's ability to modulate autonomic outflow. HRV- BF, in species, increases baroreflex sensitivity - thee body' s primary blood pressure control system.
