Aberrant Pyramidal Tract in Comparison with Pyramidal Tract on Diffusion Tensor Tractography: A Mini-Review
The pyramidal tract (PT) is a major neural tract that controls voluntary movements in the human brain. The PT has several collateral pathways, including the aberrant pyramidal tract (APT), which passes through the medial lemniscus location at the midbrain and pons. Diffusion tensor tractography (DTT) allows visualization and estimation of the APT in three dimensions. In this mini-review, eight ...
متن کاملThe pyramidal syndrome and the pyramidal tract: a brief historical note.
The discovery of the pyramidal syndrome and tract is briefly reviewed with emphasis on a few key historical aspects. The pursuit of the relationship between the lateralized deficits resulting from contralateral head trauma begins in the fourth century BC with the Hippocratic School and continues until the present day.
متن کاملMorphological evaluation of the human pyramidal tract: gender and age differences.
Using a preparation method composed of secondary chromic acid fixation, nitrocellulose embedding and Luxol fast blue-PAS-hematoxylin stain (a discriminative staining method) for the purpose of axonal discrimination, we examined 43 human spinal cords (31 males and 12 females) at the C5 level to find the differences due to gender and aging in axons of the lateral corticospinal tract. These result...
متن کاملPyramidal tract and bundle of Bagley in the goat.
In ungulates, very little is known about target areas of the fibers arising in the sensori-motor cortex. King" and Bagley", using the Marchi method, independently reported on projections from the cortical areas which they identified as motor areas by histological and/or electrophysiological methods. Besides the pyramidal tract, the latter author" described that a cortico-tegmental tract (bundle...
متن کاملThe human pyramidal syndrome Redux.
Experimental studies in nonhuman primates have questioned the selectivity of pyramidal tract damage in giving rise to the classical pyramidal syndrome in humans, characterized by permanent spastic hemiplegia (PSH). According to this view, concomitant injury of extrapyramidal pathways is necessary for the development of both hemiplegia and spasticity. In this study we used conventional magnetic ...
