通过对青蛙峡部核的连续切片重建发现，尖吻蛙核的皮质由一层细胞组成，这些细胞向后折叠，形成两个或多或少平行的面。细胞结构特征可以区分三个区域：7个“边缘区域”，以前的研究表明，它可能参与从一只眼睛到同侧顶盖叶的生理通路，以及另外两个区域，分别被称为前部和后部的“无边缘皮质”。区分边缘区域和其他两个区域的细胞结构特征在蝌蚪中基本上是不存在的。
Reconstruction of serial sections through the nucleus isthmi in the frog Rana pipiens shows that the cortex of the nucleus consists of a sheet of cells which is folded back on itself to form two more or less parallel faces. Cyto‐architectural features allow three regions to be distinguished: a 7“rim region,” which previous work had suggested may be involved in the physiological pathway from one eye to the ipsilateral tectal lobe, and two additional regions which are here termed the anterior and posterior “nonrim cortex,” re‐spectively. The cytoarchitectural features which distinguish the rim region from the other two regions are largely absent in the tadpole.
