| niger | A republic in western africa, north of nigeria and west of chad. Its capital is niamey. It was first explored by the europeans in the late 18th century.

The river's name came from the tuareg egereou n-igereouen, river of rivers, the second part of the name giving the modern european form niger. (12 Dec 1998) |
| nucleus niger | A large cell mass, crescentic on transverse section, extending forward over the dorsal surface of the crus cerebri from the rostral border of the pons into the subthalamic region; it is composed of a dorsal stratum of closely spaced pigmented (i.e., melanin-containing) cells, the pars compacta, and a larger ventral region of widely scattered cells, the pars reticulata; the pars compacta in particular includes numerous cells that project forward to the striatum (caudate nucleus and putamen) and contain dopamine, which acts as the transmitter substance at their synaptic endings; other, apparently non-dopaminergic cells of the substantia nigra project to a rostral part of the ventral nucleus of thalmus, the middle layers of the superior colliculus and to restricted parts of the reticular formation of the midbrain; the nigrostriatal projection is reciprocated by a massive striatonigral fibre system with multiple neurotransmitters, chief among which is gamma-aminobutyric acid (GABA); substantia n. Receives smaller afferent projections from the subthalamic nucleus, the lateral segment of the globus pallidus, the dorsal nucleus of the raphe and the pedunculopontine nucleus of the midbrain. The pars reticulata forms part of the output system for the striate body. The substantia n. Is involved in the metabolic disturbances associated with Parkinson's disease and Huntington's disease. Synonym: locus niger, nucleus niger, Soemmerring's ganglion. (05 Mar 2000) |

| West African sleeping sickness | A chronic disease of humans caused by Trypanosoma brucei gambiense in northern and sub-Saharan Africa from Senegal east to Sudan and Uganda; characterised by splenomegaly, drowsiness, an uncontrollable urge to sleep, and the development of psychotic changes; basal ganglia and cerebellar involvement commonly lead to chorea and athetosis; the terminal phase of the disease is characterised by wasting, anorexia, and emaciation that gradually leads to coma and death, usually from intercurrent infection.
