Abstract
  1. The arm area of the baboon's precentral motor cortex was stimulated by brief surface-anodal pulses, and the discharge of the corticospinal tract (the ;pyramidal tract waves') was recorded by an electrode resting on the dorsolateral surface of the cervical spinal cord.2. Some properties of the pyramidal tract waves were described, and they were also studied in relation to the firing of single cortico spinal fibres.3. The results led to the conclusion that the later pyramidal tract waves (the ;I waves') were almost exclusively due to a semi-synchronous repetitive discharge of the same fast cortico spinal fibres as those responsible for the initial wave (the ;D wave').4. Some problems concerning the origin and significance of the I waves were discussed.
摘要

  1. 通过短暂的表面阳极脉冲刺激狒狒中央前运动皮层的臂区，并用置于颈脊髓背外侧表面的电极记录皮质脊髓束的放电（“锥体束波”）。

  2. 描述了锥体束波的一些特性，并对其与单根皮质脊髓纤维放电的关系进行了研究。

  3. 结果得出结论，较晚出现的锥体束波（“I波”）几乎完全是由与产生初始波（“D波”）的相同快速皮质脊髓纤维的半同步重复放电所致。

  4. 讨论了有关I波起源和意义的一些问题。
