[The postnatal development of lamina V pyramidal cells in the sensomotor cortex of the albino rat. 1. Introduction and qualitative studies of Golgi preparations].
1. It is given an introductory survey about the usual Golgi procedures and modifications, and about the possible quantitative methods in Golgi researches. Upon them a synopsis of the literature about dendrite spine distribution and density in rodents' cortices (mouse, rat, hamster) follows. Concluding the preamble it is informed about the structural changes in spine distribution during postnatal ontogenesis published hitherto. 2. Using Golgi-Cox impregnated brain slices (according the RAMON-MOLINER modification) the differentiation of layer V pyramids in albino rat sensorimotor cortex during the 1st to the 90th day after birth is studied qualitatively. Several types of unknown interpyramidal synaptic contacts are published. Some notices follows about the first occurence of apical dendritic bundles during the postnatal ontogenesis, as well as about the axonal swellings of cortical pyramids.
