Serotonergic axons in the posterior cerebral cortex of the cat were demonstrated immunohistochemically using a monoclonal antibody to serotonin (5-HT). This technique reveals the presence of a dense serotonergic innervation of single cortical neurons at the light microscopic level. 5-HT axons with large varicosities (1-6 microns in diameter) form distinct, basket-like arrays around counterstained somata principally in layer I. In each basket one or more axons encircle and make repeated contact with the soma. Some axons extend from the soma and apparently climb along the dendrites of the target neuron. The climbing 5-HT axons form a stellate or horizontal pattern suggesting that the target cells are non-pyramidal neurons of the supragranular layers.
使用抗血清素（5-羟色胺，5-HT）单克隆抗体，通过免疫组织化学方法在猫大脑后皮质中显示了血清素能轴突。该技术在光学显微镜水平揭示了单个皮质神经元存在密集的血清素能神经支配。直径为1 - 6微米的有大膨体的5-HT轴突主要在第I层围绕着经复染的胞体形成独特的篮状排列。在每个篮状结构中，一条或多条轴突环绕胞体并与胞体反复接触。一些轴突从胞体伸出，明显沿着靶神经元的树突攀爬。攀爬的5-HT轴突形成星状或水平模式，表明靶细胞是颗粒上层的非锥体神经元。
