nigral

It does not have indeed a separate territory in the thalamus since its axons end together with nigral ones.

The nigral neurons also are sparsely branched and long.

Nigral axons go up dorsally without forming a clear distinctive bundle.

Pallidal and nigral terminal arborisations do not mix.

The L-Dopa therapy increases dopamine production of the remaining nigral neurons.

This part sometimes designated as VM is simply the posterior continuation of the nigral territory.

Which of these is the primary event, causing secondary changes culminating in death of the nigral cells, is not known.

I. Quanttitative morphology and typology of nigral neurons.

Nigral neurons have the same peculiar synaptology with the striatal axonal endings.

The nigral afferences come from the pars reticulata of the substantia nigra.

The difference between pallidal and nigral neurons is only in the three-dimensional extension of their dendritic arborizations.

There is indeed no more VM in the upper primates where the pallidal and nigral territories are everywhere separated.

An extracellular microiontophoretic study was made in cats of nigral neurones shown to be inhibited by caudate stimulation.

Levodopa and some of its metabolites such as dopa/dopamine quinone have also been shown to be toxic for nigral neurons.

The nigral dopaminergic input to the striatum via the nigrostriatal pathway is intimately linked with the striatum's function.

Exposure of human fetal nigral tissue to glial cell line-derived neurotrophic factor enhances survival in two patients with Parkinson's disease.

As in other vertebrates, the primate basal ganglia can be divided into striatal, pallidal, nigral, and subthalamic components.

The dendrites of the pallidal or nigral axons are entirely covered by synapses, without any apposition of glia.

It is important to stress the necessity from now to clearly distinguish the pallidal VO and the nigral VA territories.

Nigral dendrites, as well as pallidal, but not as strictly, tend to be perpendicular to the arriving stiatal axons.

The nigral neurons have their own territory distinct from the cerebellar and the pallidal in the nucleus ventralis anterior VA.

Even in the lamprey (one of the most primitive vertebrates) striatal, pallidal, and nigral elements can be identified by their anatomy and histochemistry.

The nigral target thalamic territory (VA) is medial to the pallidal (VO).

The role of the thalamus in the more anterior pallidal and nigral territories in the basal ganglia system disturbances is recognized but still poorly understood.

Pallidal axons have their own thalamic territory in the lateral region of the thalamus; everywhere separated from the cerebellar and from the nigral territories.
