在大鼠视觉皮层17区，大V层锥体细胞的大部分顶端树突聚集成定向簇，每个簇包含三个或更多这样的树突。这些团簇不是随机分布的，而是具有基本的六边形填充分布，中心到中心的平均间距为55-60微米。大多数中等大小的V层锥体细胞也将其顶端树突添加到簇中。当这些团簇穿过第四层时，它们保持完整，然后依次在第三层和最后在第二层金字塔上添加了它们的顶端树突。也许是因为在第II/III层锥体细胞如此之多，它们的一些顶端树突形成独立的群体。
In area 17 of the rat visual cortex, most of the apical dendrites of the large layer V pyramidal cells aggregate into oriented clusters, each containing three or more such dendrites. These clusters are not randomly distributed, but have a basic hexagonal packing distribution in which the mean center‐to‐center spacing is 55–60 microns. The majority of medium‐size pyramidal cells of layer V also add their apical dendrites to the clusters. As these clusters pass through layer IV they remain intact, and successively layer III and finally layer II pyramids add their apical dendrites to them. Perhaps because the pyramidal cells in layer II/III are so numerous, some of their apical dendrites form independent groups.
