狒狒中央前运动皮层的手臂区域受到短暂的表面阳极脉冲的刺激，皮质脊髓束的放电（“锥体束波”）由位于颈脊髓背外侧表面的电极记录。描述了锥体束波的一些特性，并研究了与单个皮质脊髓纤维的发射的关系。后来的锥体束波（“I 波”）几乎完全是由于与负责初始波（“D 波”）的那些相同的快速皮质脊髓纤维的半同步重复放电所致。讨论了有关I波的起源和意义的一些问题。
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. Some properties of the pyramidal tract waves were described, and studied in relation to the firing of single cortico spinal fibers. The later pyramidal tract waves (the "I waves") were almost exclusively due to a semi-synchronous repetitive discharge of the same fast cortico spinal fibers as those responsible for the initial wave (the "D wave"). Some problems concerning the origin and significance of the I waves were discussed.
