[Comparative characteristics of the dendritic spines of the 3 chief zones of the forebrain cortex of steppe and bog turtles].
A comparative study of dendritic spines in the principal cortical regions of the forebrain was performed for two turtle species by the Golgi and electron-microscopy methods. Common features of spines were revealed for every cortical region of both turtle species. Distribution peculiarities in the proximal, middle and distal sections of the spines, as well as their density, shape, length and ultrastructure were taken into account. Apart from similar features for two turtle species, there are some differences between spines of the same cortical region in Testudo horsfieldi and Emys orbicularis, which might be associated with ecological peculiarities of both species.
