A Quantitative Study on the Nigro‐Neostriatal Dopamine Neuron System in the Rat
Abstract
In a combined biochemical and histochemical investigation the following quantitative data on a unilateral nigro‐neostriatal dopamine neuron system in the rat have been obtained or calculated. — The number of neurons is 3,500 on the average. — There are about 120 pg dopamine per neuron (1 pg = 10‐12 g). — The terminals contain 50 (or 150) times more dopamine than the cell bodies. —The terminal system of one neuron varies mainly between 55 and 77 cm in length and contains about 500,000 varicosities. — The neostriatum, with a volume of 33 mm 3, contains 10 9 dopamine varicosities occupying 0.3 % of the volume, and 4,000,000 nerve cell bodies (not containing dopamine). — One average dopamine varicosity, with a diameter of 0.4 μ, contains 2.5 × 10‐4 pg dopamine, and has a dopamine concentration around 8,000 μg/g. — One dopamine cell body of the substantia nigra, with a mean diameter of 30 μ, contains 2.5 (or 0.8) pg dopamine, and has a dopamine concentration around 200 (or 60) μg/g.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
