Abstract

Autism spectrum disorder (ASD) is a common developmental disorder characterized by communication difficulties and impaired social interaction. Recent results suggest altered brain dynamics as a potential cause of symptoms in ASD. Here, we aim to describe potential information-processing consequences of these alterations by measuring active information storage (AIS)-a key quantity in the theory of distributed computation in biological networks. AIS is defined as the mutual information between the past state of a process and its next measurement. It measures the amount of stored information that is used for computation of the next time step of a process. AIS is high for rich but predictable dynamics. We recorded magnetoencephalography (MEG) signals in 10 ASD patients and 14 matched control subjects in a visual task. After a beamformer source analysis, 12 task-relevant sources were obtained. For these sources, stationary baseline activity was analyzed using AIS. Our results showed a decrease of AIS values in the hippocampus of ASD patients in comparison with controls, meaning that brain signals in ASD were either less predictable, reduced in their dynamic richness or both. Our study suggests the usefulness of AIS to detect an abnormal type of dynamics in ASD. The observed changes in AIS are compatible with Bayesian theories of reduced use or precision of priors in ASD.

  • Much of the phenomenology of autism has been cast in terms of false inference resulting from a loss of prior precision relative to sensory precision.

    “Recently, much of the phenomenology of autism has been cast in terms of false inference that results from a loss of prior precision, relative to sensory precision [74,76,77].”

    From Active interoceptive inference and the emotional brain (2016) · cites this paper as [77]

  • Autism spectrum disorder showed reduced active information storage in the hippocampus compared to healthy controls.

    “In addition, ASD showed reduced active information storage (i.e., information that is actively maintained in the brain, ready to be used (Wibral et al., 2014; Zipser et al., 1993) in the hippocampus compared to HC (G ´ omez et al., 2014).”
  • In an MEG study, individuals with autism spectrum disorder showed reduced active information storage in the hippocampus compared with typically developing individuals.

    “analysis of the active information storage (AIS), defined as mutual information in successive time points in a signal, found reduced AIS in the hippocampus in individuals with ASD compared with TD (Gomez et al., 2014)”

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.
