Page 179 - Thus, then, epilepsy appears to consist essentially in an increased reflex excitability of certain parts of the cerebro-spinal axis, and in a loss of that control which, in the normal condition, the will possesses over the reflex faculty.
Page 180 - Clon ic convulsions everywhere ; contractions of the bowels, the bladder, the uterus ; erection ; increase of many secretions ; efforts at inspiration. 9. Cessation of the convulsions...
Page 234 - ... for the symptoms. In this state of uncertainty the microscope was sent for, and I demonstrated and made evident to Drs. Paterson, Peacock, and all the students present, that the corpus striatum contained no granular corpuscles, whilst in the pons varolii they were very abundant. I have endeavored to describe what took place on this occasion, from which it must be evident that had not the microscope been appealed to, the right corpus striatum would have been pronounced softened, whilst the real...
Page 182 - ... in his sleep, or exhibited any epileptic symptoms, and that his general health had been good, and all his functions regular. Finding the patient free from any apparent disease, and that he had eaten with good appetite, and no disturbance, his usual breakfast, I desired him to get up. When, sitting up in his bed, he drew on his stockings; but on putting his feet on the floor and standing up, his countenance instantly changed, the jaw became violently convulsed, and he was about to rush forward,...
Page 191 - I have ascertained that the phenomena observed in these experiments do not depend on the section of these canals, as this operation may not cause these phenomena, but that they are the results of an irritation of the auditory nerve, from the drawing Upon It by the membranous semicircular canals at the time we divide them.
Page 201 - ... posterior columns. 9th. In the upper part of the cervical region, of the spinal cord, near the medulla oblongata, most of the conductors of the orders of the will to muscles are in the lateral columns, and in the gray matter between these and the anterior columns. 10th. The voluntary motor conductors decussate at the lower part of the oblong medulla, and not all along the median line of the base of the encephalon. llth. The posterior columns of the spinal cord have a great share in reflex movements,...
Page 149 - The reverse takes place also; the excitation of the nerves of taste produces an abundant reflex secretion of gastric juice, and also a flow of bile and pancreatic juice in the bowels.
Page 192 - The parts of the base of the encephalon which are capable of producing persistent spasms, seem to be quite different from those employed in the transmission of sensitive impressions, or of the orders of the will to the muscles, at least in the medulla oblongata and pons Varolii.
Page 243 - ... the hind legs, either spontaneously or after some external irritation. I have ascertained that the application of cold to the skin, or the pressure upon some of the paralyzed muscles, are the most powerful means of exciting those spasms. I need hardly say that in cases of local myelitis, whether in the cervical region or in the upper part of the dorsal region, spasmodic movements may also be observed in the lower limbs. In consultation with Dr. A. P. Stewart, I saw some time ago a case of this...
Page 190 - It is a fact, worthy of attention, that a puncture with a needle through the anterior pyramids, which contain very nearly all, if not all, the nerve-fibres employed in voluntary movements, will hardly produce a momentary contraction in some muscles, while certain punctures through the olivary column of the medulla oblongata at once produce a spasm of many muscles, although this column does not contain more...
