Following microinjections of the fluorescent retrograde tracer Fast blue into the substantia nigra, large numbers of retrogradely labeled cells were observed in the dorsal raphe nucleus. Using immunocytochemical techniques it could be demonstrated that the majority of these cells contained serotonin-like-immunoreactivity. In contrast, careful examination of the region of the median raphe nucleus revealed no suggestion of a significant projection from the median raphe to the substantia nigra.
在将荧光逆行示踪剂快蓝微量注射到黑质后，在中缝背核中观察到大量逆行标记的细胞。使用免疫细胞化学技术可以证明，这些细胞中的大多数含有5-羟色胺样免疫反应性。相比之下，对中缝正中核区域的仔细检查未发现中缝正中核向黑质有明显投射的迹象。
