[7 types of neurons in the substantia nigra of the rat. Golgi rapid-impregnation study]. 1982

H Danner, and C Pfister

The substantia nigra of the adult rat was investigated by means of the Golgi rapid impregnation technique. Seven neuron types could be distinguished which differ with respect to morphological features (size and shape of pericaryon and dendritic pattern), behaviour of axons and prevalent localization within the nuclear area: 1. Polygonal neurons with somatic spines 2. Polygonal neurons without somatic spines 3. Fusiform neurons 4. Trigonal neurons 5. Small spherical neurons 6. Small spindle-shaped neurons 7. Neuroglioform neurons. The neuron types 1-4 are considered to represent nigral projection neurons; the types 5-7 might be interneurons. The findings presented here are discussed in view of recent physiological and biochemical as well as behavioral-pharmacological results.

UI	MeSH Term	Description	Entries
D008297	Male		Males
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
D003712	Dendrites	Extensions of the nerve cell body. They are short and branched and receive stimuli from other NEURONS.	Dendrite
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.	Animal,Metazoa,Animalia
D001369	Axons	Nerve fibers that are capable of rapidly conducting impulses away from the neuron cell body.	Axon
D013194	Staining and Labeling	The marking of biological material with a dye or other reagent for the purpose of identifying and quantitating components of tissues, cells or their extracts.	Histological Labeling,Staining,Histological Labelings,Labeling and Staining,Labeling, Histological,Labelings, Histological,Stainings
D013378	Substantia Nigra	The black substance in the ventral midbrain or the nucleus of cells containing the black substance. These cells produce DOPAMINE, an important neurotransmitter in regulation of the sensorimotor system and mood. The dark colored MELANIN is a by-product of dopamine synthesis.
