Synaptic ribbons, functionally enigmatic structures of mammalian pinealocytes, were studied during the postnatal development of the pineal gland in the golden hamster (Mesocricetus auratus). On day 4 post partum, synaptic ribbons appear in cells that have already started to differentiate into pinealocytes. Between days 4 and 9, an increase in the number of synaptic ribbons occurs, concomitant with the continuing differentiation of the pineal tissue. Between days 9 and 16, when differentiation of this tissue is almost completed, the number of synaptic ribbons decreases and approaches that characteristic of the adult pineal gland. During development, the synaptic ribbons increase in length, and dense core vesicles are frequently found in the vicinity of these structures. It is assumed that a functional relationship exists between dense core vesicles and the synaptic ribbons, which are considered to be engaged in a certain form of secretory activity of the mammalian pineal gland.
突触带是哺乳动物松果体细胞中功能神秘的结构，我们在金黄仓鼠（Mesocricetus auratus）松果体的产后发育过程中对其进行了研究。产后第4天，突触带出现在已经开始分化为松果体细胞的细胞中。在第4天至第9天之间，突触带数量增加，同时松果体组织持续分化。在第9天至第16天之间，当该组织的分化几乎完成时，突触带数量减少并接近成年松果体的特征数量。在发育过程中，突触带长度增加，并且在这些结构附近经常发现致密核心囊泡。据推测，致密核心囊泡与突触带之间存在功能关系，而突触带被认为参与了哺乳动物松果体某种形式的分泌活动。
