Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1921 edition. Excerpt: ...an attempt to cast a very extensive group of symptoms in much top narrow a mould. Furthermore it is only rarely that lesions are observed so strictly localized as to reproduce mesencephalic transection in man. A very significant fact in Wilson's group of cases presenting supposed decerebrate symptoms is the rather diffuse character of the lesions in many of them. There are also included such clinical conditions as cerebral diplegia, infantile hemiplegia, microcephaly with diplegia and athetoid attitude, as well as cases of chorea and athetosis, all as presenting partial or fragmentary signs of decerebrate rigidity, in the sense in which the term is used by Sherrington. That postural symptoms, both general and local, more or less suggestive of experimental decerebrate rigidity are also encountered in man is unquestionable, but that these are all to be referred exclusively to the midbrain level is, in my opinion, more than doubtful. In the first place I would recall that the decerebrate posture or attitude is of the automatic-associated type and represents a fixation in terms of posture of a well-known automatic-associated act. As the corpus striatum is the essential organ for the correlation of automatic-associated types of movement, a release of this mechanism, as occurs in such disorders as chorea and athetosis, would liberate movements of this type and among others those suggestive of the decerebrate postures of the extremities and trunk. Furthermore, in the cortical or pyramidal types of palsy with loss of isolated-synergic movements, there are present numerous associated movements, many of which emanate from the striatal mechanism. Certain of these movements of the automatic-associated type when localized in the hand and arm may...show more
