Abstract

Mice unable to synthesize dopamine (DA) specifically in dopaminergic neurons were created by inactivating the tyrosine hydroxylase (TH) gene then by restoring TH function in noradrenergic cells. These DA-deficient (DA-/-) mice were born at expected frequency but became hypoactive and stopped feeding a few weeks after birth. Midbrain dopaminergic neurons, their projections, and most characteristics of their target neurons in the striatum appeared normal. Within a few minutes of being injected with L-dihdroxyphenylalanine (L-DOPA), the product of TH, the DA-/- mice became more active and consumed more food than control mice. With continued administration of L-DOPA, nearly normal growth was achieved. These studies indicate that DA is essential for movement and feeding, but is not required for the development of neural circuits that control these behaviors.

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.
