  • The functional role of reactive astrocytes after stroke is controversial. To elucidate whether reactive astrocytes contribute to neurological recovery, we compared behavioral outcome, axonal remodeling of the corticospinal tract (CST), and the spatio-temporal change of chondroitin sulfate proteoglyc

  • Following spinal cord injury (SCI), limit spontaneous functional recovery often emerged. However, the neuronal mechanisms associated with this phenomenon still remains obscure. By using proteomics analysis, endoplasmic reticulum protein 29 (ERp29) was discovered to increase in the motor cortexes of

  • Background Hereditary spastic paraplegia is a neurodegenerative phenotype characterized by a progressive loss of corticospinal motor tract function. In a majority of affected individuals the pathogenesis remains undetermined. Methods We identified a series of patients with a phenotype of nonsynd

The pyramidal tracts refers to both the corticospinal' and corticobulbar tracts. The corticospinal tract conducts impulses from the brain to the spinal cord. It contains mostly motor axons. The corticospinal tract is made up of two separate tracts in ...
The lateral corticospinal tract (also called the crossed pyramidal tract or lateral cerebrospinal fasciculus) is the largest part of the corticospinal tract. It extends throughout the entire length of the medulla spinalis, and on transverse section ...

  • 大脳の運動野にあるBetzの巨大錐体細胞などから起こり、内包の膝と後脚の前半部を通過し、大脳脚の中央1/3を通り、胸腹側部を経て脊髄腹側に錐体として出現。さらに下降する際は大部分の線維は錐体交叉で対側に写り脊髄側索の背側半を外側皮質脊髄路となって下降していく。
