In response to a repeated photic stimulation of moderate intensity EMG-responses appeared in neck, ear, fore- and hind-limbs muscles of a rabbit, with no tendency to extinction. Animal's position had a considerable effect on the probability of occurence of EMG-responses. The probability was similar for all muscles, making 30% when the rabbit was fixed in a lying position (posture I) and about 15% when the animal was in a natural sitting position (posture II). The response latencies, recorded in limb muscles, varied considerably, the distribution maximum occurring at 0.4--0.6 sec. In rabbits in posture I the fore-leg was involved into reaction more rapidly than the hind-leg. In rabbits in posture II no such difference was observed. It is assumed that EMG-responses to indifferent stimuli reflect rearrangements occuring primarily in the postural system and contributing to animal's activity readiness.
对兔子颈部、耳部、前肢和后肢肌肉进行中等强度的重复光刺激时，会出现肌电图反应，且无消退趋势。动物的姿势对肌电图反应出现的概率有相当大的影响。所有肌肉的概率相似，兔子固定为躺卧姿势（姿势I）时为30%，处于自然坐姿（姿势II）时约为15%。在肢体肌肉中记录的反应潜伏期差异很大，分布峰值出现在0.4 - 0.6秒。姿势I的兔子前腿比后腿更快参与反应。姿势II的兔子未观察到这种差异。据推测，对无关刺激的肌电图反应主要反映姿势系统中发生的重新调整，并有助于动物的活动准备状态。
