Pyramidal tract responses during seizures
Electroencephalography and Clinical Neurophysiology, 1965Abstract 1. 1. Responses to stimulation of the sensorimotor cortex were recorded from the ipsilateral medullary pyramid during seizures in locally anesthetized, paralyzed cats. Seizures were induced either by i.v. administration of Metrazol or by high frequency stimulation of the ipsilateral sensorimotor cortex. 2. 2.

Throughout the short history of experimental brain research, the pyramidal tract has attracted much interest from bram scientists (for a detailed account about the history of the pyramidal tract, see Lassek, 1954). Early research on the structure and function of the brain in the nineteenth century was most often performed in a clinical neurological ...

The Babinski toe sign is regarded by many clinicians as the most important superficial reflex used in neurologic diagnosis because it is thought to be indicative of destruction of the pyramidal tract. There is difference of opinion as to whether irritation of the bundle can also produce the reflex.

Knowledge of the pyramidal system is incomplete and confused because too much reliance has been placed on study of normal histologic material rather than on critical experimental methods. This is especially true of the rabbit. According to Linowiecki,1the pyramidal tract of the rabbit is located in the lateral funiculus of the spinal cord.

Pyramidal tract lesions in comatose patients
Acta Neurochirurgica, 1991In 197 comatose patients transcranial magnetic evoked potentials were registered to investigate the integrity of the pyramidal tract. Findings were compared to somatosensory, visual and auditory evoked potentials. Preservation, abnormalities and absence of evoked potentials were related to survival and non-survival.

Because of the lack of agreement existing in respect to the origin of the pyramidal tract, it was thought that the application of a refined silver stain to the lower part of the human pyramid might give a clue as to its cells of origin and, in addition, furnish information about the size and number of its component fibers.

Abstract Pure X-linked spastic paraplegia, MASA, and X-linked hydrocephalus due to an acqueduct stenosis, seem to be the result of the mutations of the same gene called Li-CAM. The same mutation in a single family can result in different phenotypes.

The postnatal changes in the performance of the striated muscles of man must depend on concomitant alterations in the efferent structures of the nervous system and muscles. The pyramidal tract, because of its isolation and accessibility in the pyramids, offers an opportunity to compare the development of somatic motor neurons and function subsequent to

The present investigation is a continuation of anatomic studies on the pyramidal tract of man and is directed at a classification of the large cells of the motor cortex (area 4 of Brodmann). In spite of the fact that the cells designated as Betz or giant cells are probably the best known in the cerebral hemisphere, it is not possible to give an ...

The present study is an attempt to correlate the symptoms and signs of the pyramidal tract syndrome with the Babinski reflex. A destructive upper motor neuron lesion involving the pyramidal bundle has been said traditionally to produce the following abnormalities: paralysis of the spastic type; hyperactive tendon reflexes; loss of the superficial ...
