The circadian control of the calling song of crickets is abolished by severance of the optic lobes. The arrhythmic singing activity of operated animals is unaffected by all possible light conditions, yet the singing can be reentained by a daily temperature cycle. The characteristics of this reentrainment indicate the that temperature is acting as an actual Zeitgeber. In light of these results the current hypothesis which ascribes a driving oscillator function to the optic lobes must be reevaluated.
切除蟋蟀的视叶会消除其鸣叫的昼夜节律控制。手术动物的无节律鸣叫活动不受所有可能光照条件的影响，但鸣叫可以通过每日温度循环得以恢复。这种重新同步化的特征表明温度起着实际的授时因子的作用。鉴于这些结果，必须重新评估当前将驱动振荡器功能归因于视叶的假设。
