脊髓 spinal cord

脊椎动物背部正中从前向后走行的白色素状物。与脑相连，并和脑一起构成中枢神经系统。它和脑都是由神经管分化产生的。其中心有纵行的连接脑室的中央管（analis centralis），围着中央管的灰质构成脊髓的内层，外层由白质构成。在脊髓的横切面上，灰质呈 H形，由连结左右两角的灰质和中央部的中央灰质（ substantia grisea centralis）组成。前者又分为背腹二部，分别称为前角（ cornu ven－ trale） =前灰柱（ columna ventralis），后角

Functional MRI of the Spinal Cord

Evidence to date shows that fMRI of the spinal cord (spinal fMRI) can reliably demonstrate regions involved with sensation of tactile, thermal, and painful stimuli, and with motor tasks. The spin-echo-based spinal fMRI method with “signal

Spinal Cord MR of Rodent Models

Different MR techniques, such as relaxation times, diffusion, perfusion, and spectroscopy have been employed to study rodent spinal cord. In this chapter, a description of these methods is given, along with examples of normal metrics
