比较了海鱼有髓神经和无髓神经中质子的磁共振弛豫率。鱼的长而大的嗅觉神经，作为无髓鞘轴突的一个容易获得的来源，是唯一适合这样的比较。T1和T2测量显示无髓鞘嗅觉神经和有髓鞘视神经和动眼神经之间存在明显和一致的差异。水含量、脂质含量和弛豫率的比较表明，磁共振性质的差异代表了组成脂质和水质子的分布和物理环境的复杂差异。
The magnetic resonance (MR) relaxation rates of protons were compared in the myelinated and nonmyelinated nerves of the garfish. The long, large olfactory nerve of the garfish, as an easily accessible source of nonmyelinated axons, is uniquely suited for such a comparison. The T1 and T2 measurements revealed distinct and consistent differences between nonmyelinated olfactory nerves and myelinated optic and oculomotor nerves. Comparisons between water content, lipid content, and relaxation rates indicated that the differences in MR properties represent complex differences in the distribution and physical environment of the constituent lipid and water protons.
