Effects of Alcohol on the Brain
I, on one occasion had the strange, though
miserable, chance of viewing a similar occurrence in the brain
construction of a person, who, in an outburst of alcoholic
exhilaration, beheaded himself under the wheels of a train, and
whose brain immediately came out from its skull by the collision.
The brain itself, whole, was in front of me within one eight
seconds after the end. It emitted the strong smell of spirit most
markedly, and its thin, skin-like structures and tiny
constructions were extremely bloody. It appeared as though it had
been freshly infused with a brilliant red pigment. The white stuff
of the cerebrum, decorated with red spots, could hardly be made
out, when it was slit opened, by its inherent paleness; plus the
pia-mater, or inner vascular membrane casing the brain, looked
like a flimsy mesh of congealed red blood, so tautly were its
slender vessels bloated.
I should further say that this condition
continued through the smaller and the larger brain, the cerebellum
and the cerebrum, but wasn’t so noticeable in either the medulla
or the spinal cord’s beginning section.
The Spinal Cord & Nerves:
The alcohol’s action carried on past the
initial stage, the spinal cord’s performance is affected. When in
good physical shape, we are used, via the nervous system’s this
part, to execute routine tasks very mechanically, which continue
methodically even while we are caught up with or discussing other
subjects. Hence, a competent tradesman will carry on his
mechanical job without a glitch, while his intellect is set on
some other matter; and so we all execute different tasks in a
wholly automatic manner, without requesting for assistance from
the superior centers, barring when something out of the ordinary
happens to command their service, whereupon we reflect before we
do something. Under the effects of alcohol, the spinal centers
become impacted, and these sheer automatic functions stop being
properly executed. That a hand may get to any object, or a foot be
properly placed, the superior brain center must be called upon to
ensure that the happening takes place safely. A defective ability
of coordinating the muscular movement ensues rapidly. The nervous
system’s control of some of the body muscles is missing, plus the
nervous stimulus almost is weakened. In humans the lower lip
muscles are the first to fail, followed by the lower limb muscles,
and it is significant to note that the body’s extensor muscles
yield before the flexors. By this time, the muscles themselves are
also becoming weak; they react more weakly than is normal to the
nerve stimulation; they, also, are succumbing to the dampening
effects of the benumbing agent, their arrangement is momentarily
disturbed, and their ability to contract is decreased.
This variation of the animal acts under alcohol
indicates the second level of its effects. In youthful subjects,
there is at this point, normally, nausea with dizziness, followed
by slow respite from the weight of the venom.
How It Effects The Brain Centers
The alcoholic spirit taken to yet an additional
level, the brain centers or the cerebral are impacted; they are
diminished in ability, and the controlling stimuli of resolve and
of decisions are missing. As these centers are disturbed and
driven crazy, the balanced part of the personality of the man
yields before the sentimental, organic, or arousing part. The
sanity is now not at work, or is playing with work, and all the
sheer animal impulses and responses are laid appallingly naked.
The poltroon appears more gutless, the braggadocio more grandiose,
the brutal more heartless, the deceitful more insincere, the
lascivious more sullied. ' In vino veritas ' conveys, even,
without a doubt, to physiological exactness, the real state. The
sanity, the feelings, the senses, all are in a festive state, and
in disordered weakness.
Lastly, the effects of alcohol still running
on, the advanced brain centers are subjugated; the senses are
fogged up, the controlled muscular prostration is sharpened,
emotional response is haywire, and the body rests as a plain block
of wood, lifeless by all but a quarter, on which merely its life
suspends. The heart still keeps on doing what it has to do, and
while it simply exists, it nourishes the respiratory power. And
hence the respiration and circulation, in the otherwise still
bulk, maintain the body within the sheer realm of life till such
time the venom starts to withdraw and the nervous centers start to
perk up again. It is fortunate for the intoxicated that,
generally, the brain stops working much before the heart does, and
that he neither has the strength nor the intellect to carry on his
process of damage until he stops to breathe. Thus he survives to
perish another day.
