[Density of distribution of nerve cells in the nuclei of the cat's trigeminal complex].
The results of calculation of nerve cells density in each of the four nuclei composing the nuclear complex of the trigeminal nerve are presented. The quantitative data were processed by non-parametrical statistical method. It was established that the whole rostral half of the trigeminal complex of the nuclei had greater density of cell distribution, than the caudal one. Especially pronounced was the difference in the density of disposition of cells between the nuclei occupying the extreme-caudal and rostral position in the general complex of nuclei. Comparison of the obtained facts with the literature data and the author's previous investigations has shown that the revealed distinctions are in agreement with pecularities of the structural functional organizations of the trigeminal complex, according to which the structure is changed from the caudal to rostral end to be more isolated from the reticular formation, and the function is changed to conduct more delicate differentiated stimuli.
