Abstract

Cerebellar involvement in autism, schizophrenia, and other cognitive disorders is typically associated with prefrontal cortical pathology. However, the underlying neuronal mechanisms are largely unknown. It has previously been shown in mice that stimulation of the dentate nucleus (DN) of the cerebellum evokes dopamine (DA) release in the medial prefrontal cortex (mPFC). Here, we investigated the neuronal circuitry by which the cerebellum modulates mPFC DA release. Fixed potential amperometry was used to determine the contribution of two candidate pathways by which the cerebellum may modulate mPFC DA release. In urethane anesthetized mice, DA release evoked by DN stimulation (50 Hz) was recorded in mPFC following local anesthetic lidocaine (0.02 μg) or ionotropic glutamate receptor antagonist kynurenate (0.5 μg) infusions into the mediodorsal or ventrolateral thalamic nucleus (ThN md; ThN vl), or the ventral tegmental area (VTA). Following intra-VTA lidocaine or kynurenate infusions, DA release was decreased by ∼50%. Following intra-ThN md and ThN vl infusions of either drug, DA release was decreased by ∼35% and 15%, respectively. Reductions in DA release following lidocaine or kynurenate infusions were not significantly different indicating that neuronal cells in the VTA and ThN were activated primarily if not entirely by glutamatergic inputs. The present study suggests that neuropathological changes in the cerebellum commonly observed in autism, schizophrenia, and other cognitive disorders could result in a loss of functionality of cerebellar-mPFC circuitry that is manifested as aberrant dopaminergic activity in the mPFC. Additionally, these results specifically implicate glutamate as a modulator of mPFC dopaminergic activity.

  • Repeated stimulation of the cerebellum increases dopamine in the mouse medial prefrontal cortex.

    “The existence of such a pathway would explain how repeated stimulation of the cerebellum increases dopamine in the mouse medial prefrontal cortex (Rogers et al., 2011).”
  • Dentato-thalamo-cortical neurons are thought to be glutamatergic, implicating glutamate as a modulator of mPFC dopaminergic activity.

    “The dentato-thalamo-cortical neurons are thought to be glutamatergic and thus implicate glutamate as a modulator of mPFC dopaminergic activity [179].”
  • Cerebellar pathology in autism and other cognitive disorders could result from functional loss of cerebellar-mPFC circuitry due to abnormal dopaminergic activity in mPFC.

    “It has been recently reported that cerebellar pathology in autism and other cognitive disorders could result from the functional loss of cerebellar-mPFC circuitry due to abnormal dopaminergic activity in the mPFC [179].”
  • Recent studies report cerebellar control of dopamine release in prefrontal cortex, a mechanism that might be triggered by spatiotemporal cortical activity patterns.

    “Important new clues, however, come from recent studies reporting cerebellar control of dopamine release in the prefrontal cortex [179, 180], a mechanism that might be triggered by spatiotemporal cortical activity patterns, as proposed here.”
  • Changes in cerebellar-mPFC functional connectivity have been identified in mouse models of cerebellar PC loss and in genetic mouse models of ASD.

    “in mouse models of cerebellar PC loss, and in genetic mouse models of ASD17,18.”

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.
