The Alcohol Question.--It is agreed by investigators that in large or
continued amounts alcohol has a narcotic effect; that it first dulls or
paralyzes the nerve centers which control our judgment, and later acts upon
the so-called motor centers, those which control our muscular activities.
The reason, then, that a man in the first stages of intoxication talks
rapidly and sometimes wittily, is because the centers of judgment are
paralyzed. This frees the speech centers from control exercised by our
judgment, with the resultant rapid and free flow of speech.
In small amounts alcohol is believed by some physiologists to have always
this same narcotic effect, while other physiologists think that alcohol
does stimulate the brain centers, especially the higher centers, to
increased activity. Some scientific and professional men use alcohol in
small amounts for this stimulation and report no seeming harm from the
indulgence. Others, and by far the larger number, agree that this
stimulation from alcohol is only apparent and that even in the smallest
amounts alcohol has a narcotic effect.
The Paralyzing Effects of Alcohol on the Nervous System.--Alcohol has the
effect of temporarily paralyzing the nerve centers. The first effect is
that of exhilaration. A man may do more work for a time under the
stimulation of alcohol. This stimulation, however, is of short duration and
is invariably followed by a period of depression and inertia. In this
latter state, a man will do less work than before. In larger quantities,
alcohol has the effect of completely paralyzing the nerve centers. This is
seen in the case of a man "dead drunk." He falls in a stupor because all of
the centers governing speech, sight, locomotion, etc., have been
temporarily paralyzed. If a man takes a very large amount of alcohol, even
the nerve centers governing respiration and circulation may become
poisoned, and the victim will die.
