  • Hereditary diffuse leukoencephalopathy with axonal spheroids (HDLS) is a rare autosomal dominant disease caused by mutations within the colony stimulating factor 1 receptor (CSF1R) gene. While a small number of reports on imaging findings in routine MRI exist, reported imaging findings in DWI and sp

  • The current optimal surgery for glioblastomas (GBMs) near the pyramidal tract (PT) is to remove as much tumor as possible and to preserve motor function. The purpose of this study is to investigate the usefulness of tractography-integrated navigation-guided fence-post catheter techniques and motor-e

  • The nature of memory is a central issue in neuroscience. How does our representation of the world change with learning and experience Here we use the transcription of Arc mRNA, which permits probing the neural representations of temporally separated events, to address this in a well characterized o

  • 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。
