With the indirect immunofluorescence technique using antisera to three catecholamine synthesizing enzymes, labeled periglomerular cells as well as their intraglomerular processes were observed in the turtle olfactory bulb. These cells could also be recognized in the EPL and the glomerular layer. Unlabeled periglomerular cells were also seen. Thick labeled processes (presumably dendrites) entered the glomerular neuropil, and there formed a dense network, with numerous terminal varicosities. These results support the existence of a unique, homologous dopaminergic subdivision of the periglomerular interneurons throughout classes of vertebrates. In addition, a second type of weakly tyrosine hydroxylase immunoreactive neurons was observed in the outer part of the granule layer. Dopamine beta-hydroxylase positive fibers were seen in the granule, mitral and external plexiform layers.
利用针对三种儿茶酚胺合成酶的抗血清的间接免疫荧光技术，在龟的嗅球中观察到了标记的球周细胞及其球内突起。在外部丛状层（EPL）和肾小球层也能识别出这些细胞。也可见未标记的球周细胞。粗大的标记突起（可能是树突）进入肾小球神经毡，并在那里形成一个密集的网络，有许多终末膨体。这些结果支持在整个脊椎动物类群中存在一种独特的、同源的球周中间神经元多巴胺能亚群。此外，在颗粒层外部观察到第二种弱酪氨酸羟化酶免疫反应性神经元。在颗粒层、僧帽细胞层和外部丛状层可见多巴胺β-羟化酶阳性纤维。
