Abstract

Significance: The basal ganglia process cortical information that controls purposeful movements and appropriate behavior via the striatopallidal and striatonigral pathways. Despite their importance, little is known about the developmental mechanisms that control the formation of these pathways. We show here that telencephalic progenitors expressing the transcription factor Islet1 give rise to striatonigral neurons and that this factor is required for normal development of the striatonigral pathway. Moreover, Islet1 mouse mutants exhibit hyperactivity and a paradoxical response to psychostimulants. Given that the underlying causes of basal ganglia disorders such as attention deficit hyperactivity disorder (ADHD) are unknown, these findings may implicate possible alterations in neural circuitry.

  • Isl1 is widely expressed in hypothalamus and CNU, and more highly in GABAergic than glutamatergic cell types.

    “Isl1 is widely expressed in hypothalamus and CNU, and more highly in GABAergic than glutamatergic cell types115.”

    From A high-resolution transcriptomic and spatial atlas of cell types in the whole mouse brain (2023) · cites this paper as [115]

    The Results (page unavailable) report Isl1 expression in a subpopulation of developing striatal neurons and in adult neurons of the rTh and zona incerta; fate-mapped striatal neurons have characteristics of GABAergic projection neurons. The paper does not establish widespread expression across the hypothalamus and CNU or compare Isl1 expression levels in GABAergic and glutamatergic cell types. (LLM, conf=0.83)

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.
