Abstract

It is widely accepted that D1 dopamine receptor-expressing striatal neurons convey their information directly to the output nuclei of the basal ganglia, whereas D2-expressing neurons do so indirectly via pallidal neurons. Combining optogenetics and electrophysiology, we found that this architecture does not apply to mouse nucleus accumbens projections to the ventral pallidum. Thus, current thinking attributing D1 and D2 selectivity to accumbens projections akin to dorsal striatal pathways needs to be reconsidered.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Recent findings show that these neat divisions do not apply as simplistically to the ventral striatum.

    “More recent findings have established that these neat divisions do not apply as simplistically to the ventral striatum [221,222].”
  • D1 medium spiny neurons project to the ventral tegmental area and ventral pallidum, while D2 medium spiny neurons project to the ventral pallidum.

    “NAc D1-MSN and D2-MSNs are also distinguished by their projections to target regions: D1-MSNs target the ventral tegmental area (VTA) and ventral pallidum (VP), while D2-MSNs specifically target the VP (FIGURE 1) (19–21).”

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.
