Segregated fronto-cerebellar circuits revealed by intrinsic functional connectivity

Abstract

Multiple, segregated fronto-cerebellar circuits have been characterized in nonhuman primates using transneuronal tracing techniques including those that target prefrontal areas. Here, we used functional connectivity MRI (fcMRI) in humans (n = 40) to identify 4 topographically distinct fronto-cerebellar circuits that target 1) motor cortex, 2) dorsolateral prefrontal cortex, 3) medial prefrontal cortex, and 4) anterior prefrontal cortex. All 4 circuits were replicated and dissociated in an independent data set (n = 40). Direct comparison of right- and left-seeded frontal regions revealed contralateral lateralization in the cerebellum for each of the segregated circuits. The presence of circuits that involve prefrontal regions confirms that the cerebellum participates in networks important to cognition including a specific fronto-cerebellar circuit that interacts with the default network. Overall, the extent of the cerebellum associated with prefrontal cortex included a large portion of the posterior hemispheres consistent with a prominent role of the cerebellum in nonmotor functions. We conclude by providing a provisional map of the topography of the cerebellum based on functional correlations with the frontal cortex.

  • Word retrieval is accompanied by activation in the right vermal and hemispheric components of lobule VI and Crus I and II of lobule VII in the posterior lateral cerebellum.

    “and this was accompanied by activation in the right vermal and hemispheric components of lobule VI and Crus I and II of lobule VII in the posterior lateral cerebellum (Krienen and Buckner, 2009; Murdoch, 2010; Stoodley and Shamahmann, 2009, 2010).”
  • Polysynaptic connections between the cerebellum and the cortex have been demonstrated in anatomic tracing and functional connectivity studies.

    “Polysynaptic connections between the cerebellum and the cortex have been demonstrated both in anatomic tracing studies and functional connectivity studies9,10,11,12,13.”
  • Connectivity exists between the left mPFC and Rcrus1 in humans and primates.

    “We and others previously demonstrated connectivity between the left mPFC and Rcrus1 in humans and primates8,9,10.”
  • Functional connections exist between the cerebellar cortex and cerebral cortical areas in the regulation of complex non-motor behavior.

    “support functional connections between the cerebellar cortex and cerebral cortical areas in the regulation of complex non-motor behavior3,9,10,19.”
  • The interaction of the cerebellum with higher-order intrinsic connectivity networks could modulate executive function, mentalizing, and salience detection, functions critical for social cognition and social interaction.

    “Specifically, the interaction of the cerebellum with higher-order intrinsic connectivity networks (Habas et al., 2009, Krienen and Buckner, 2009) could similarly modulate executive function, mentalizing, and salience detection − functions critical for social cognition and social interaction (Menon, 2011).”

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.
