针对在简单视觉反应时间条件下进行的单侧快速手臂屈曲运动（Belen'kii、Gurflnkel 和 Pal'tsev，1967），检查了任务肌肉和姿势肌肉的运动前（预期）活动的多成分模式。受试者连续四天每天进行 30 次右侧反应和 30 次左侧反应。预期的姿势肌肉活动可以被认为是自愿单侧手臂弯曲的有效组成部分。神经肌肉模式的空间和时间特征的不变性和可变性通过与反应组织的行为和运动控制模型的关系来描述。建议响应组件之间的某些时间模式可能不会集中预编程。
A multicomponent pattern of premovement (anticipatory) activity in both task and postural muscles was examined for a unilateral rapid arm flexion movement (Belen'kii, Gurflnkel, & Pal'tsev, 1967) performed under simple visual reaction-time conditions. Subjects performed 30 right- and 30 left-side responses on each of four consecutive days. The anticipatory postural muscle activity may be considered a valid component of voluntary unilateral arm flexion. Invariances and variability in the spatial and temporal characteristics of the neuromuscular pattern are described in relationship to behavioral and motor control models of response organization. It is suggested that some temporal patterning among response components may not be preprogrammed centrally.
