由完全包含在脊髓内的神经元组成的固有脊髓系统很重要，因为它构成了许多脊髓行为的基础。为了提供有关这一系统的定量数据，本研究测定了分离的S2猫脊髓中轴突的数量，并将这些数字与正常值进行了比较。结论是，该位置脊髓内60%的纤维是固有脊髓。特别值得注意的是，绝大多数无髓固有脊髓轴突位于外侧索的背侧，在背索内有大量有髓下行纤维下行。这些数据将作为评估轴突数量的基础，这些轴突数量遵循各种据称导致神经萌发的实验方案。
The propriospinal system, which consists of those neurons completely contained within the spinal cord, is important because it underlies much spinal behavior. To provide quantitative data on this system, the present study determines numbers of axons in the isolated S2 cat spinal cord and compares these figures with the normal. The conclusion is that 60% of the fibers in the spinal cord at this location are propriospinal. Findings of particular interest are that the great majority of unmyelinated propriospinal axons are found in the dorsal part of the lateral funiculus, and that there are large numbers of descending of descending myelinated fibers in the dorsal funiculi. These data will serve as a basis for evaluating axon numbers that follow various experimental regimens purporting to result in neural sprouting.
