[Analysis of the neuronal dendrite system of the olfactory bulb in the dog brain].

A technique was worked out for quantitative analysis of accurate neuron drawings obtained from the preparations impregnated after Golgi. The analysis (according to 13 parameters) was performed to study the dendritic system within one main class of long-axonal neurons in layer II in areas having heterogenous structures of the polyfunctional formation in the dog cerebral olfactory tubercle. The most stable parameters were demonstrated to be the linear dimension of the cell body, branching of the apical and basal dendritic systems, as well as branching of the whole neuronal dendritic system. Values of other parameters change with statistical significance depending on the fact to what areas with heterogenous structures of the olfactory tubercle the neurons belong. The data obtained demonstrate a greater pyramidization of the neural class studied in the rostral portion and their similarity in the median and caudal portions of the olfactory tubercle and the neurons of highly differentiated subcortical nuclei.
