These receptors act together to increase sympathetic nervous system output and decrease parasympathetic nervous system output. Since the resumption of meiotic progression is accompanied by oocyte membrane depolarisation, parasympathetic innervation could exert an inhibitory effect on oocyte maturation. Parasympathetic and sympathetic nervous system activity has been associated with two frequency bands. Parasympathetic and sympathetic nervous system activity have been associated with two frequency bands. Individual differences in the reactivities of sympathetic and parasympathetic divisions of the brain's autonomic centres should therefore also be relevant to the efficiency of socialization. There is also an increase in sympathetic versus parasympathetic activity9 which predisposes to a greater degree of peripheral vasodilation. The natural logarithm of the variance in high frequency hear t period was calculated to estimate parasympathetic activity. As the above literature review suggests, however, aggressive samples are characterized by deficiencies in parasympathetic functioning. Thus, although the number of findings is not large, results from both children and adults suggest reduced parasympathetic tone in aggression. As indicated above, the parasympathetic pathway to the eye subserves two functions. Heart-rate response tests predominantly parasympathetic and blood pressure responses predominantly sympathetic autonomic function. If the parasympathetic activity index shows stress and the sympathetic activity index shows stress, the stress in the subject is highest. If the parasympathetic activity index shows relaxation and the sympathetic activity index shows relaxation, the stress in the subject is least. These changes were consistent with increased sympathetic or decreased parasympathetic tone. It was demonstrated that acute changes occurred in non-invasive and invasive measures consistent with increased sympathetic or decreased parasympathetic tone. The parasympathetic nervous system is involved in gastrointestinal responses to stress, eating and behaviour and consists of afferent as well as efferent neurons. Sympathetic and parasympathetic innervation and circulating neurohormones also affect sinus node automaticity and conduction. It is mediated through parasympathetic and beta adrenergic mechanisms. Thus attempts can be made to stimulate the oral receptors (afferent pathways) or alternatively, to act directly on the parasympathetic nerves (efferent pathways). Parasympathetic innervation is by the recurrent laryngeal nerve and the vagus. Parasympathetic nerves arise from stretch receptors in the bladder wall and are relayed via the sacral centre. In our laboratory investigations are in progress to analyse the participation of the parasympathetic neurotransmitter, acetylcholine, in oocyte maturation. Acetylcholine-evoked currents in cultured neurones dissociated from rat parasympathetic cardiac ganglia. The vagus, the primary parasympathetic pathway to the heart, rapidly regulates cardiac output during environmental challenge. If the parasympathetic activity index shows stress and the sympathetic activity index shows relaxation, the stress in the subject is medium.
