The pineal organs of the adult domestic mallard, fowl and pigeon were investigated by means of neurohistological techniques and electron microscopy. The application of opsin immunocytochemistry to the pineal organ of the domestic mallard reveals antigenic sites in the outer segments of the pinealocytes. Avian pinealocytes may establish synaptic contacts to intrapineal neurons via complex neuropil formations. Bundles of nerve fibers resembling the pineal tract of poikilothermic vertebrates were found in the pineal stalk. These findings strengthen the view that the avian pineal organ has not lost its photoreceptive capacity.
利用神经组织学技术和电子显微镜对成年家鸭、家禽和鸽子的松果体进行了研究。在家鸭松果体上应用视蛋白免疫细胞化学技术，揭示了松果体细胞外段的抗原位点。禽类松果体细胞可能通过复杂的神经毡结构与松果体内的神经元建立突触联系。在松果体柄中发现了类似于变温脊椎动物松果体束的神经纤维束。这些发现强化了这样一种观点，即禽类松果体并未丧失其感光能力。
