Neural connections of the small parapineal organ of the adult rainbow trout were experimentally investigated by using a lipophilic carbocyanine dye as a tracer. The dye was applied to the parapineal organ, to the pineal organ, or to the left or right habenular ganglion. The parapineal organ mainly projected via a coarse parapineal tract to a conspicuous neuropil in the rostrodorsal part of the left habenular ganglion. A small accessory parapineal tract projecting to the right habenular ganglion was also found in some animals. No pineal afferents were observed in the parapineal, nor was any neuron in the brain seen to project to this organ. These results suggest a functional relationship of the parapineal organ to the limbic system.
利用亲脂性碳青霉烯染料作为示踪剂，对成年虹鳟鱼的小松果旁器官的神经连接进行了实验研究。将染料应用于松果旁器官、松果体器官或左侧或右侧缰神经节。松果旁器官主要通过一条粗大的松果旁束投射到左侧缰神经节 rostrodorsal 部分的一个明显的神经毡。在一些动物中还发现了一条投射到右侧缰神经节的小的副松果旁束。在松果旁未观察到松果体传入纤维，在脑中也未发现任何神经元投射到该器官。这些结果表明松果旁器官与边缘系统之间存在功能关系。
