The rat olfactory bulb was studied with the Falck-Hillarp formaldehyde fluorescence technique, including recent modifications, autoradiography and electron microscopic cytochemistry (permanganate fixation). Some periglomerular cells and few superficial tufted cells take up and accumulate catecholamines and precursors. They probably represent dopamine cells. In the glomeruli, probable 5-hydroxy-tryptamine nerve terminals could be identified. In the granular and external plexiform layers, noradrenaline axon terminals were present. At the ultrastructural level, monoamine boutons were in synaptic contact with dendritic spines of granule cells and in the glomeruli, probable 5-hydroxytryptamine boutons formed synapses with periglomerular cell dendrites. Therefore, monoamine afferents to the bulb may exert their influence via interneurons.
采用福尔克-希拉尔普甲醛荧光技术（包括近期的改进方法）、放射自显影术和电子显微镜细胞化学技术（高锰酸盐固定）对大鼠嗅球进行了研究。一些球周细胞和少数浅层簇状细胞摄取并积累儿茶酚胺及其前体。它们可能代表多巴胺能细胞。在肾小球中，可以识别出可能的5-羟色胺神经末梢。在颗粒层和外丛状层中，存在去甲肾上腺素轴突末梢。在超微结构水平上，单胺终扣与颗粒细胞的树突棘形成突触联系，在肾小球中，可能的5-羟色胺终扣与球周细胞树突形成突触。因此，传入嗅球的单胺可能通过中间神经元发挥其影响。
