Synaptic ribbons were studied in the pineal system of the golden hamster (Mesocricetus auratus) under various conditions of light deprivation. Five weeks of constant darkness led to an increase in the number of synaptic ribbons in both the superficial and the deep part of the organ, and after ten weeks a further increase was observed. In animals returned to normal lighting conditions for one week, after ten weeks of constant darkness, a marked decrease was recorded and five weeks after termination of light deprivation the number of synaptic ribbons was slightly below the normal level. In addition to long rod-shaped ribbons, atypically formed aggregations of electron dense material appear in the synaptic ribbon fields of light-deprived hamsters; dense core vesicles were observed in the vicinity of the ribbons with particular frequency. It is assumed that the topographical relationship between dense core vesicles and synaptic ribbons is of functional significance in relation to the regulation of pineal antigonadal activity.
在不同光照剥夺条件下，对金黄仓鼠（Mesocricetus auratus）松果体系统中的突触带进行了研究。持续五周的黑暗导致该器官浅层和深层的突触带数量增加，十周后观察到进一步增加。在持续黑暗十周后恢复正常光照条件一周的动物中，记录到突触带数量显著减少，且在光照剥夺结束五周后，突触带数量略低于正常水平。除了长杆状的突触带外，在光照剥夺的仓鼠的突触带区域还出现了非典型形成的电子致密物质聚集；在突触带附近特别频繁地观察到致密核心囊泡。据推测，致密核心囊泡与突触带之间的拓扑关系在松果体抗性腺活动的调节方面具有功能意义。
