The paper presented results of a quantitative Golgi study of developing neurons of the brain stem reticular nuclei of prenatal and newborn kittens. Age of prenatal animals was 45-55 days, that of newborns 1-5 and 30 days. The neurons were divided into sparsely ramified reticular and densely ramified multipolar giant ones. The quantitative morphological data were obtained by measuring cellular sizes, number, length and degree of branching of dendrites and general cell branching. The neurons of both kinds had different parameters and special features of their maturation. A higher degree of branching was observed in the fetus. Foci of maximal dendrite branching were localized in proximal and distal portions of dendrites in the fetus and 30-day old kittens, and only in proximal portions in the infant kitten. An attempt was made to correlate morphological and electrophysiological properties of the neurons under study.

UI	MeSH Term	Description	Entries
D009474	Neurons	The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM.	Nerve Cells,Cell, Nerve,Cells, Nerve,Nerve Cell,Neuron
D012154	Reticular Formation	A region extending from the PONS & MEDULLA OBLONGATA through the MESENCEPHALON, characterized by a diversity of neurons of various sizes and shapes, arranged in different aggregations and enmeshed in a complicated fiber network.	Formation, Reticular,Formations, Reticular,Reticular Formations
D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D003712	Dendrites	Extensions of the nerve cell body. They are short and branched and receive stimuli from other NEURONS.	Dendrite
D004594	Electrophysiology	The study of the generation and behavior of electrical charges in living organisms particularly the nervous system and the effects of electricity on living organisms.
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
