Abstract

The topographic pattern of neurons in spinal nerve sensory ganglion and of sympathetic trunk cervicothoracic ganglion was investigated at adult rats (n=12). Results of the work have shown, that these organs are characterized by a heterogeneity of the neurons according to their morphometric (Nissl's stain) and histochemical (acetylcholinestherase and NADPH-diaphorase activity) parameters. The common feature of ganglia organization was demonstrated by the clustered pattern of neuron topography. Clusters were formed on a principle of heterogeneity, uniting from 3-4 to 9-10 neurons. The application of a combined histochemical method has allowed to identify the histo-functional charactristics of neurons within the clusters of the ganglia studied, which were also detected by standard histological methods.
