The anterior ventral nucleus neurons in of the camel brain were morphologically studied by Golgi impregnation method. Two neuronal types of were found in the camel anterior ventral thalamic nucleus, namely, Golgi-type I neurons and Golgi-type II neurons. Those neurons were generally similar to their counterparts in the human thalamus. The Golgi-type I neurons exhibited medium to large cell body (mean diameter = 25 μm) which was either multipolar or triangular in shape. They had from 3 to 10 primary dendrites with many branches but with no spines or appendages. The Golgi-type II neurons had small to medium size (somatic mean diameter = 17.5 μm), their cell bodies were variable in shape, some were round, and others were multipolar or fusiform. These cells bodies had two to six primary dendrites with few branches that may have spines and/or grape-like appendages. Our findings shed some light on the anterior ventral thalamic nucleus structure of the camel as one of the strongest adaptive mammals to the hard climatic conditions.
采用高尔基染色法对骆驼脑前腹侧核神经元进行了形态学研究。在骆驼前腹侧丘脑核中发现了两种神经元类型，即高尔基Ⅰ型神经元和高尔基Ⅱ型神经元。这些神经元通常与人类丘脑的对应神经元相似。高尔基Ⅰ型神经元的细胞体为中等至大型（平均直径为 25μm），呈多极或三角形。它们有 3 到 10 条初级树突，有许多分支，但没有棘突或附属物。高尔基Ⅱ型神经元的细胞体较小至中等大小（体细胞平均直径为 17.5μm），形状多变，有些呈圆形，有些呈多极或梭形。这些细胞体有 2 到 6 条初级树突，分支较少，可能有棘突和/或葡萄状附属物。我们的发现为骆驼前腹侧丘脑核结构提供了一些线索，因为它是对恶劣气候条件适应能力最强的哺乳动物之一。
