0 relating to the parasympathetic nervous system (= the system that controls functions that cannot be controlled, such as slowing the heart beat and producing tears): --
It was demonstrated that acute changes occurred in non-invasive and invasive measures consistent with increased sympathetic or decreased parasympathetic tone.
These changes were consistent with increased sympathetic or decreased parasympathetic tone.
If the parasympathetic activity index shows relaxation and the sympathetic activity index shows relaxation, the stress in the subject is least.
If the parasympathetic activity index shows stress and the sympathetic activity index shows stress, the stress in the subject is highest.
Heart-rate response tests predominantly parasympathetic and blood pressure responses predominantly sympathetic autonomic function.
As indicated above, the parasympathetic pathway to the eye subserves two functions.
Thus, although the number of findings is not large, results from both children and adults suggest reduced parasympathetic tone in aggression.
As the above literature review suggests, however, aggressive samples are characterized by deficiencies in parasympathetic functioning.
