Hughlings Jackson has observed that limited and general convulsions were
often produced by disease in the cortex of the so-called motor
convolutions. The sense of smell has been localized by Munk in the gyri
hippocampi, while the center of hearing has been demonstrated to be in
the temporal lobes. The center for the muscles of the face and tongue is
in the inferior part of the central convolution; that for the arm, in the
central part; that for the leg, in the superior part of the same
convolution; the center for the muscles and for general sensibility, in
the angular gyrus; and the center for the muscles of the trunk, in the
frontal lobes. In pure motor aphasia the lesion is in the posterior part
of the left third frontal convolution; in cases of pure sensory aphasia,
the lesion is in the left first temporal convolution.
The relation of the cerebrum to cutaneous diseases has been studied much
of late, and it is now held that the cutaneous eruptions are mainly due
to the degree of inhibiting effect exerted upon the vaso-motor center.
The relation of the spinal cord to skin eruptions has been more
thoroughly investigated and more abundant evidence supplied to
demonstrate the influence degeneration of the spinal cord has in causing
skin diseases, notably zoster, urticaria, and eczema.
This rheumatism, pneumonia, diabetes, and some kidney diseases and liver
affections are often the result of persistent nervous disturbance is now
held. That a high temperature (the highest recorded) has resulted from
injuries of the spinal cord, and where the influence of microzymes is
excluded, is not a matter of question. In one instance, the temperature
reached 122° F., and remained for seven weeks between 108° and 118° F.
The patient was a lady; the result was recovery. Hence it cannot be fever
which kills or produces rapid softening of the heart and other organs in
fatal cases of typhoid. Fever, so far as it consists in elevation of
temperature, can be a simple neurosis.
Many other items of progress might be presented did time permit,
particularly in the treatment of nervous affections, but this I leave for
another occasion.
