Partially enhanced thalamocortical functional connectivity in autism

Abstract

Based on evidence for thalamic abnormalities in autism, impairments of thalamocortical pathways have been suspected. We examined the functional connectivity between thalamus and cerebral cortex in terms of blood oxygen level dependent (BOLD) signal cross-correlation in 8 male participants with high-functioning autism and matched normal controls, using functional MRI during simple visuomotor coordination. Both groups exhibited widespread connectivity, consistent with known extensive thalamocortical connectivity. In a direct group comparison, overall more extensive connectivity was observed in the autism group, especially in the left insula and in right postcentral and middle frontal regions. Our findings are inconsistent with the hypothesis of general underconnectivity in autism and instead suggest that subcortico-cortical connectivity may be hyperfunctional, potentially compensating for reduced cortico-cortical connectivity.

  • An increased number of thalamocortical synapses occur in layer IV of the somatosensory cortex of 4-month-old Fmr1 KO mice.

    “An increased number of thalamocortical synapses occur in layer IV of the somatosensory cortex of 4-month-old Fmr1 KO mice and altered thalamocortical connectivity is also implicated in ASD (Mizuno et al., 2006; Cheon et al., 2011; Nair et al., 2013).”

  • Increased local and reduced long-range FC characteristic of immature development has been reported to be widespread in Tourette's disorder and was also found in ADHD.

    “increased local and reduced long-range FC- characteristic of immature development- has been reported to be widespread in Tourette’s disorder (along with two anomalous circuits) (67) and was also found in ADHD (68).”
  • Functional hyperconnectivity in clinical populations is increasingly interpreted as reflecting delayed or stunted maturational processes.

    “Functional hyperconnectivity in clinical populations is increasingly interpreted as reflecting delayed or stunted maturational processes.”
  • Mizuno et al. (2006) found evidence for hyper-connectivity between thalamus and cerebral cortex using BOLD signal cross-correlation.

    “In contrast, however, Mizuno, Villalobos, Davies, Dahl, and Muller (2006) found evidence for hyper-connectivity between thalamus and cerebral cortex using BOLD signal cross-correlation.”

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.
