The cat globus pallidus (GP) was found to contain both small and large cells that stain lightly and intensely for acetylcholinesterase (AChE), respectively. The small GP cells are similar to entopeduncular (EN) cells and it is proposed that both should be considered as 'typical' pallidal neurons. In contrast, large GP cells are similar to intensely stained AChE cells present in the substantia innominata (SI) and the putamen (PUT). Furthermore, HRP injection into the neocortex was found to label numerous large AChE cells in GP and a lesser number of similar neurons in PUT and SI. No HRP labeling was observed in the smaller cells of EN, GP and PUT. These findings suggest that the magnocellular AChE neurons in feline basal ganglia may be part of a single population of 'limbic' elements.
猫的苍白球（GP）被发现含有小细胞和大细胞，它们分别对乙酰胆碱酯酶（AChE）进行轻度和强烈染色。小的苍白球细胞类似于脚内核（EN）细胞，有人提出两者都应被视为“典型的”苍白球神经元。相比之下，大的苍白球细胞类似于无名质（SI）和壳核（PUT）中存在的强染色AChE细胞。此外，发现将辣根过氧化物酶（HRP）注入新皮质会标记苍白球中大量的大AChE细胞，以及壳核和无名质中数量较少的类似神经元。在脚内核、苍白球和壳核的较小细胞中未观察到HRP标记。这些发现表明，猫基底神经节中的大细胞AChE神经元可能是单一“边缘”元素群体的一部分。
