The claustrum is a subcortical nucleus, found in the telencephalon of all placental mammals. Earlier Golgi studies have mostly focused on a qualitative description of the types of neurons. The aim of the present study was to describe the types of neurons found in the dorsal claustrum of the cat using the Golgi impregnation method and to perform a quantitative analysis of the following morphometric parameters: number of terminals (ends), total dendritic length, dendritic complexity, spine density (in spiny projection neurons), varicosity density (in aspiny interneurons). We used specimens from 5 healthy male cats stained according to the Golgi-Cox method. The dendritic trees of the studied neurons were then reconstructed through the Neurolucida software. Values of the studied quantitative parameters were obtained automatically and tested for statistically significant differences. Five types of spiny neurons were observed—large, medium-sized and small multipolar, bipolar and pyramidal-like. In addition, we described three types of aspiny neurons. The quantitative values and the statistical analysis were presented with tables and diagrams. In conclusion, we have presented a detailed analysis of the cytoarchitecture of the DC of the cat and have reported the first quantitative data on a number of morphometric parameters.

猫背锁骨的细胞结构：高尔基体定量研究。

锁骨是皮层下的核，存在于所有胎盘哺乳动物的端脑中。高尔基早期的研究主要集中在对神经元类型的定性描述上。本研究的目的是使用高尔基浸渍法描述猫背锁骨中发现的神经元类型，并对以下形态计量参数进行定量分析：末端数量（末端），总树突长度，树突状复杂性，脊柱密度（在棘突状神经元中），静脉曲张密度（在棘突间神经元中）。我们使用了根据高尔基-柯克斯方法染色的5只健康雄性猫的标本。然后通过Neurolucida软件重建所研究神经元的树突树。自动获得研究的定量参数的值，并测试其统计学上的显着差异。观察到五种类型的多刺神经元-大，中型和小型多极，双极和金字塔形。此外，我们描述了三种类型的棘突神经元。定量值和统计分析用表格和图表表示。总之，我们对猫的DC的细胞结构进行了详细分析，并报告了许多形态计量学参数的第一批定量数据。定量值和统计分析用表格和图表表示。总之，我们对猫的DC的细胞结构进行了详细分析，并报告了许多形态计量学参数的第一批定量数据。定量值和统计分析用表格和图表表示。总之，我们对猫的DC的细胞结构进行了详细分析，并报告了许多形态计量学参数的第一批定量数据。
