Abstract
Pineal structural and biochemical adaptations in lanternfishes included: 1) few photoreceptor outer segment discs; 2) conventional synapses between photoreceptors and pineal neurons; and 3) low levels (0-60 pg/pineal) of serotonin compared to those (greater than 1.0 ng/pineal) in the goldfish pineal organ. These findings suggest reduced photosensory and/or neuroendocrine functions in these deep-sea fishes.
摘要
灯笼鱼松果体的结构和生化适应性包括
1）光感受器外段盘较少；2）光感受器与松果体神经元之间存在传统突触；3）与金鱼松果体器官中（大于1.0 ng/松果体）的血清素水平相比，血清素水平较低（0 - 60 pg/松果体）。这些发现表明这些深海鱼类的光感和/或神经内分泌功能有所降低。
