If the vaso-motor centre of the brain is only influenced when the ganglia at the base are called into activity, and if their activity coincides with emotion, and not with thought, whose organ is much more remote, in the cerebral hemispheres, it should follow that emotion, and not thought, should most easily influence the vaso-motor centre, and be followed by peculiar modifications of the ganglionic system and of the circulation.
The classification of sex is certainly one of those that offer an interesting opportunity for such comparison, especially in regard to the relations existing between the operations of the ganglionic, and those of the cerebro-spinal system.
Clarke, insist on the incompatibility between cerebral action and the process of ovulation, imply a predominance of ganglionic activity in women that must render them the physiological inferiors of the animals or individuals in whom no such incompatibility exists.
One should salute a gentleman in yawning, salute him in hiccuping, salute him in sneezing, salute him in coughing, and that evidently because of your interest in his health; for he may dislocate his jaw in yawning, and the hiccup is often a symptom of grave disorder, and sneezing is perilous to the small blood-vessels of the head, and coughing is either a tracheal, bronchial, pulmonary, or ganglionic affection."
Complacently he sat and smiled, little witting that his son's ordeal was imminent, and that his son's ordeal was to be his own. Hippias wrote that his nephew was killing him by making appointments which he never kept, and altogether neglecting him in the most shameless way, so that his ganglionic centre was in a ten times worse state than when he left Raynham.
Finally, in these cases, the resulting disease is seated in the brain or spinal column. This latter remark is of great importance for our purpose; for it tends to show that diseases produced elsewhere within the range of the ganglionic system of nerves as the menstrual hæmorrhage, that we are especially considering must be due to some other nervous act than that of thought.
We shall find that the flesh is made up of bundles of strong fibres. The brain and nerves, too, we shall find, are made up of fibres, and these queer-looking things that are called ganglionic corpuscles.
"If any one who may not just like an actual dissection, will look at one of Quain's 'Plates of the Bones, Muscles, and Nerves of the Human Body, he will see that, growing as it were out of the walls of the stomach, there are, in our wonderful human machine, great bunches of nerves, called, by the medicals, the 'great ganglionic system, and he will observe that these nerves are in intimate and inseparable connection with the spinal cord, and the brain.
If excessive action of the brain or spinal cord be analogous in its effects to galvanism of a spinal nerve, it might be supposed to cause vaso-motor paralysis and hæmorrhage. 3d. In general exhaustion of the nervous system, both of its ganglionic and cerebro-spinal apparatus, the vaso-motor nerves suffer with the rest, and the blood-vessels lose their tone in consequence.
