Cerebellar modulation of the reward circuitry and social behavior
Open accessAbstract
The cerebellum and reward-driven behavior: Damage to the cerebellum manifests itself in various forms of cognitive impairment and abnormal social behavior. However, the exact role the cerebellum plays in these conditions is far from clear. Working in mice, Carta et al. found direct projections from the deep cerebellar nuclei to the brain's reward center, a region called the ventral tegmental area (see the Perspective by D'Angelo). These direct projections allowed the cerebellum to play a role in showing a social preference. Intriguingly, this pathway was not prosocial on its own. Cerebellar inputs into the ventral tegmental area were more active during social exploration. Depolarization of ventral tegmental area neurons thus represents a similar reward stimulus as social interaction for mice. Science , this issue p. eaav0581 ; see also p. 229

The cerebellum sends an excitatory efferent signal to the ventral tegmental area (VTA).
“Tracing and optogenetic activation of cerebellar projections in mice show that the cerebellum sends an excitatory efferent signal to the ventral tegmental area (VTA; Carta et al., 2019).”

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.
