| Abstract: | Computerized morphometric techniques were used to investigate each of 23 parameters in three types of brain stem reticular nucleus neurons in Golgi-stained frontal slices from the brain of 30-day-old kittens after uni- and bilateral lingual nerve section 5–7 days after birth. Particular statistically significant differences in some parameters were discovered in all types of cell. Certain group-specific differences in parameters could be most frequently distinguished in each category: distribution of loose dendritic endings through the dendritic area in reticular neurons, length of dendritic segments in branching cells, and distribution of foci of dendritic arborization in giant multipolar neurons. Unilateral lingual nerve section results in quantitatively more marked deviation from the normal state. It was only under these circumstances, moreover, that differences in overall length of dendrites could be seen, which could indicate a difference in the surface area of the cell.Institute of Higher Nervous Activity and Neurophysiology, Academy of Sciences of the USSR, Moscow.
