How Alcohol Affects the Brain
I once had the unusual, though unhappy, opportunity of
observing the same phenomenon in the brain structure of a man,
who, in a paroxysm of alcoholic excitement, decapitated himself
under 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 within 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 was incised, by its
natural whiteness; and 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 should add that this condition extended through both the
larger and the smaller brain, the cerebrum and cerebellum, but
was not so marked in the medulla or commencing portion of the
spinal cord.
The spinal cord and nerves.
--------------------------
The action of alcohol continued beyond the first stage, the
function of the spinal cord is influenced. Through this part of
the nervous system we are accustomed, in health, to perform
automatic acts of a mechanical kind, which proceed
systematically even when we are thinking or speaking on other
subjects. Thus a skilled workman will continue his mechanical
work perfectly, while his mind is bent on some other subject;
and thus we all perform various acts in a purely automatic way,
without calling in the aid of the higher centres, except
something more than ordinary occurs to demand their service,
upon which we think before we perform. Under alcohol, as the
spinal centres become influenced, these pure automatic acts
cease to be correctly carried on. That the hand may reach any
object, or the foot be correctly planted, the higher
intellectual centre must be invoked to make the proceeding
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 the nervous stimulus is
more or less enfeebled. The muscles of the lower lip in the
human subject usually fail first of all, then the muscles of
the lower limbs, and it is worthy of remark that the extensor
muscles give way earlier than the flexors. The muscles
themselves, by this time, are also failing in power; they
respond more feebly than is natural to the nervous stimulus;
they, too, are coming under the depressing influence of the
paralyzing agent, their structure is temporarily 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
is now, usually, vomiting with faintness, followed by gradual
relief from the burden of the poison.
Effect on the brain centres.
----------------------------
The alcoholic spirit carried yet a further degree, the
cerebral or brain centres become influenced; they are reduced
in power, and the controlling influences of will and of
judgment are lost. As these centres are unbalanced and thrown
into chaos, the rational part of the nature of the man gives
way before the emotional, passional or organic part. The reason
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 more craven, the braggart more boastful, the
cruel more merciless, the untruthful more false, the carnal
more degraded. ' In vino veritas ' expresses, even, indeed, to
physiological accuracy, the true condition. The reason, the
emotions, the instincts, are all in a 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 heart still
remains true to its duty, and while it just lives it feeds the
breathing power. And so the circulation and the respiration, in
the otherwise inert mass, keeps the mass within the bare domain
of life until the poison begins to pass away and the nervous
centres to revive again. It is happy for the inebriate that, as
a rule, the brain fails so long before the heart that he has
neither the power nor the sense to continue his process of
destruction up to the act of death of his circulation.
Therefore he lives to die another day.
