Fig. 1. Morphology and computational model of the monkey cervical spinal cord.
a Macroscopic organization of the cervical spinal cord. Left: relationships between spinal segments, spinal roots, and vertebrae. Right: cross-sections at the C5 and T1 segmental levels showing the internal compartmentalization of the spinal cord. b Spinal segments dimensions. The two shades of gray indicate measurements coming from two different spinal cord dissections. c Tridimensional view of the volume conductor. d Trajectories of virtual nerve fibers and motoneurons. e Compartmentalization of myelinated nerve fibers and motoneurons used in neurophysical simulations32,37,39.
