Abstract

Persistent and ramping neural activity in the frontal cortex anticipates specific movements 1-6. Preparatory activity is distributed across several brain regions 7,8, but it is unclear which brain areas are involved and how this activity is mediated by multi-regional interactions. The cerebellum is thought to be primarily involved in the short-timescale control of movement 9-12; however, roles for this structure in cognitive processes have also been proposed 13-16. In humans, cerebellar damage can cause defects in planning and working memory 13. Here we show that persistent representation of information in the frontal cortex during motor planning is dependent on the cerebellum. Mice performed a sensory discrimination task in which they used short-term memory to plan a future directional movement. A transient perturbation in the medial deep cerebellar nucleus (fastigial nucleus) disrupted subsequent correct responses without hampering movement execution. Preparatory activity was observed in both the frontal cortex and the cerebellar nuclei, seconds before the onset of movement. The silencing of frontal cortex activity abolished preparatory activity in the cerebellar nuclei, and fastigial activity was necessary to maintain cortical preparatory activity. Fastigial output selectively targeted the behaviourally relevant part of the frontal cortex through the thalamus, thus closing a cortico-cerebellar loop. Our results support the view that persistent neural dynamics during motor planning is maintained by neural circuits that span multiple brain regions 17, and that cerebellar computations extend beyond online motor control 13-15,18.

  • Recent evidence in rodents shows that persistence of neuronal firing rates for working memory storage is not purely cortical but relies on interactions with subcortical structures including thalamus and cerebellar nuclei.

    “Recent evidence in rodents demonstrated that the persistence of neuronal firing rates for working memory storage is not a purely cortical phenomenon but instead relies on the interactions with subcortical structures, including the thalamus (Guo et al., 2017) and cerebellar nuclei (Gao et al., 2018).”

  • Persistent-activity reverberatory loops involve not only corticocortical connections but also subcortical regions, especially the thalamus and cerebellar nuclei.

    “recent experimental evidence indicates that the reverberatory loops for persistent neuronal activity not only involve corticocortical interactions but also loop through subcortical regions with an important role for the thalamus and cerebellar nuclei (Gao et al., 2018; Guo et al., 2017).”

  • The cerebellum provides output to the cortex and tunes sensory input to facilitate behavioral adjustment in response to feedback.

    “The cerebellum provides output to the cortex, and “tunes” sensory input to facilitate behavioral (particularly motor) adjustment in response to feedback(25–27).”

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.
