As shown by histofluorescence studies, a number of brain stem serotoninergic neurons have their cell bodies and dendrites in intimate contact with parenchymal blood vessels, including arterioles (perivascular serotoninergic neurons). Another, apparently distinct, phenomenon which was evidenced is the existence of a diffuse innervation by long serotoninergic axons of intrinsic blood vessels. These axons seem to be continuous with an adventitial nerve fiber network surrounding extrinsic blood vessels. A novel significant finding was that some of the perivascular neurons themselves can project an axonic process into the wall of the same vessel they embrace with their cell body and dendrites (a receptive as well as a vasomotor function?).
组织荧光研究表明，许多脑干5-羟色胺能神经元的细胞体和树突与实质血管密切接触，包括小动脉（血管周围5-羟色胺能神经元）。另一个明显不同的现象是，内在血管存在由长5-羟色胺能轴突构成的弥散性神经支配。这些轴突似乎与围绕外在血管的外膜神经纤维网络相连。一项新的重要发现是，一些血管周围神经元自身能够将轴突突入它们的细胞体和树突所环绕的同一血管壁内（具有感受功能以及血管舒缩功能？）
