Page 181 - 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 32 - IB able either to cure or to relieve these epileptic animals. The convulsive affection existing in almost all these animals was the consequence of a transversal section of a lateral half of the spinal cord, in the dorsal or in the lumbar region. I have already published the results of my experiments on epilepsy, in my lectures before large classes of Physicians and Medical students, both in France in 1851 and in this country in 1852. These results are in perfect accordance with the views of Dr. Marshall...
Page 236 - 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 lesion in the pons varolii might have escaped observation. Under such circumstances this case would have added another to the inexplicable observations with which the records of nervous diseases abound.
Page 184 - ... 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 193 - 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 235 - Several persons applied their fingers, and endeavored to ascertain the point. As the manual examination proceeded, the normal consistence of the part diminished, until at length it presented all the appearance of pultaceous softening. In this state it was shown to Dr. Paterson, who naturally enough considered it to be the result of disease. I differed from him in opinion : first, because I had carefully observed the gradual increase of the softening in the manner alluded to ; and secondly, because...
Page 184 - The nail was perfect ; there was not the least swelling or redness in the surrounding parts, nor any tenderness or uneasiness felt when I compressed the toe laterally, or moved it, held thus, in any direction ; but on the bulb of the toe, nearly at the point where the circumgyrations of the cuticle centre, there was a very small elevation, as if a bit of gravel less than the head of a small pin had been there pressed in beneath the cuticle. There was not the least redness on this spot, nor any sensation...
Page 171 - Suppose a worm in the bowels irritating their centripetal nerve fibres : the irritation is propagated to the spinal cord, which reflects it upon the roots of the cervical sympathetic nerve, by which it reaches the blood-vessels of the retina, produces their contraction, and, as a consequence of this cause of diminution in the amount of blood, an amaurosis. If instead of the reflex action on the blood-vessels, there is an action on the tissues, as in the case of the experiments of Czermak and of Prof....
Page 203 - ... 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 151 - 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.
