Abstract

The initial burst has been re-examined following conditioning of the muscle to investigate its intrafusal origins. The burst was present in the response to stretch of spindle afferents that innervated the bag1 fibre and those that did not. There was, however, a difference in amplitude of the burst. These findings are discussed in terms of intrafusal mechanisms.

摘要

在对肌肉进行预处理后，对最初的爆发活动进行了重新检查，以研究其肌梭内起源。在对支配袋1纤维的梭内传入纤维和未支配袋1纤维的梭内传入纤维的拉伸反应中均出现了爆发活动。然而，爆发活动的幅度存在差异。从肌梭内机制的角度对这些发现进行了讨论。
