HOW ALCOHOL AFFECTS THE BRAIN.
I once had the unusual, though unhappy, chance of observing the same phenomenon within the brain structure of a man, who, in an exceedingly paroxysm of alcoholic excitement, decapitated himself underneath the wheel of a railway carriage, and whose brain was instantaneously evolved from the skull by the crash. The brain itself, entire, was before me inside three minutes after the death. It exhaled the odor of spirit most distinctly, and its membranes and minute structures were vascular in the extreme. It looked as if it had been recently injected with vermilion. The white matter of the cerebrum, studded with red points, could scarcely be distinguished, when it had been incised, by its natural whiteness; and also the pia-mater, or internal vascular membrane covering the brain, resembled a delicate web of coagulated red blood, so tensely were its fine vessels engorged.
I ought to add that this condition extended through both the larger and also the smaller brain, the cerebrum and cerebellum, however wasn’t therefore marked in the medulla or commencing portion of the spinal cord.
The spinal wire and nerves.
————————–
The action of alcohol continued beyond the first stage, the function of the spinal wire is influenced. Through this part of the nervous system we have a tendency to are accustomed, in health, to perform automatic acts of a mechanical kind, that proceed systematically even after we are thinking or speaking on other subjects. Therefore a talented workman can continue his mechanical work perfectly, whereas his mind is bent on some other subject; and thus we have a tendency to all perform various acts during a purely automatic means, without calling in the aid of the upper centres, except one thing more than standard occurs to demand their service, upon that we suppose before we have a tendency to perform. Below alcohol, as the spinal centres become influenced, these pure automatic acts stop to be properly carried on. {That the} hand may reach any object, or the foot be properly planted, the upper intellectual centre should be invoked to make the continuing secure. There follows quickly upon this a deficient power of co-ordination of muscular movement. The nervous control of certain of the muscles is lost, and also the nervous stimulus is additional or less enfeebled. The muscles of the lower lip in the human subject typically fail 1st of all, then the muscles of the lower limbs, and it’s ought to have remark {that the} extensor muscles give manner sooner than the flexors. The muscles themselves, by this point, are also failing in power; they respond more feebly than is natural to the nervous stimulus; they, too, are coming back beneath the depressing influence of the paralyzing agent, their structure is briefly deranged, and their contractile power reduced.
This modification of the animal functions under alcohol, marks the second degree of its action. In young subjects, there’s currently, sometimes, vomiting with faintness, followed by gradual relief from the burden of the poison.
Effect on the brain centres.
—————————-
The alcoholic spirit carried nevertheless a more degree, the cerebral or brain centres become influenced; they are reduced in power, and therefore the controlling influences of will and of judgment are lost. As these centres are unbalanced and thrown into chaos, the rational part of the character of the person offers way before the emotional, passional or organic part. The rationale is now off duty, or is fooling with duty, and all the mere animal instincts and sentiments are laid atrociously bare. The coward shows up a lot of craven, the braggart more boastful, the cruel a lot of merciless, the untruthful additional false, the carnal a lot of degraded. ‘ In vino veritas ‘ expresses, even, indeed, to physiological accuracy, the true condition. The explanation, the emotions, the instincts, are all in a very state of carnival, and in chaotic feebleness.
Finally, the action of the alcohol still extending, the superior brain centres are overpowered; the senses are beclouded, the voluntary muscular prostration is perfected, sensibility is lost, and the body lies a mere log, dead by all but one-fourth, on which alone its life hangs. The center still remains true to its duty, and while it simply lives it feeds the respiration power. And so the circulation and also the respiration, within the otherwise inert mass, keeps the mass among the bare domain of life until the poison begins to pass away and therefore the nervous centres to revive again. It is happy for the inebriate that, most of the time, the brain fails therefore long before the heart that he has neither the facility nor the sense to continue his process of destruction up to the act of death of his circulation. Thus he lives to die another day.
