In vertebrates (excluding mammals), the rest is presented also by a special functional condition of the catalepsy type. In hens, its total duration is higher in the day-time, than in the twilight; it is completely absent at night. This natural condition in hens may be imitated by photogenic catalepsy which is developed in response to rhythmic illumination of animals. Cytospectrophotometric investigation of single cells of the supraoptic nucleus indicates that with respect to absence of changes in absolute content (per 1 cell) of protein in the neurons cataleptiform rest in hens does not differ from the sleep in rats. However, in contrast to sleep this immobilization is associated with the decrease of RNA content of the neurons, as well as with the absence of accumulation of proteins and RNA in gliocytes. During cataleptiform rest, insiginficant changes were found in the content of proteins and RNA in cells of ectomammilar nucleus of the additional optic system and thalamic round nucleus. Cataleptiform (photogenic) immobilization in hens is presumably a metabolically passive form of rest as compared to the sleep in rats, which is characterized by anabolic processes in the brain.
在脊椎动物（不包括哺乳动物）中，其余部分也表现为一种特殊的僵住症类型的功能状态。在母鸡中，其总时长在白天比在黄昏时长，在夜间则完全不存在。母鸡的这种自然状态可以通过光致僵住症来模拟，光致僵住症是动物对有节奏的光照产生的反应。对视上核单细胞的细胞分光光度法研究表明，就母鸡僵住样静止状态下神经元中蛋白质的绝对含量（每1个细胞）没有变化而言，它与大鼠的睡眠并无不同。然而，与睡眠相反，这种静止状态与神经元RNA含量的减少有关，也与神经胶质细胞中蛋白质和RNA的积累缺失有关。在僵住样静止期间，在附加视系统的乳头外侧核和丘脑圆形核的细胞中，蛋白质和RNA的含量发现有不显著的变化。与以大脑合成代谢过程为特征的大鼠睡眠相比，母鸡的僵住样（光致）静止状态大概是一种代谢被动的休息形式。
