Cutaneous and subcutaneous TNS embodiments are disclosed for addressing autonomic nervous system imbalances. A cutaneous electrode assembly is applied to a patient's forehead, and a current is pulsed through the electrode assembly to stimulate the supraorbital and supratrochlear nerves on the patient to increase activity for the patient's parasympathetic nervous system. Pulsing the current increases the power spectral density for the patient's heart rate variability in a 0.1 to 0.15 Hz frequency band.
