[Quantitative studies on the comparability of neurohistological results in rat cortical pyramids produced by different Golgi methods (author's transl)].

By the spine distribution and the spine density of layer V pyramids in albino rat sensorimotor cortex the following GOLGI methods are compared with together quantitatively: GOLGI-KOPSCH, GOLGI-BUBENAITE, GOLGI-Rapid by Virktorov and GOLGI-COX by Ramón-Moliner. Whereas the Kopsch, Bubenaite and Ramón-Moliner impregnations obtain the same results in all signs examined here (with the exception of a higher number of dendritic spines in the first 50 microgram of apical dendrites using the Ramón-Moliner procedure), the GOLGI-Rapid method diverges considerably from the other GOLGI procedures. Using the GOLGI-Rapid method remarkable fewer spines are impregnated. So the results of GOLGI-Rapid cannot be compared with the other GOLGI procedures events.
