A resting EEG study of neocortical hyperexcitability and altered functional connectivity in fragile X syndrome.

Open access

Abstract

BACKGROUND: KO mice, a mouse model of the fragile X syndrome which is the most common single gene cause of autism and intellectual disability. METHODS: We collected resting state dense-array electroencephalography data from 21 fragile X syndrome (FXS) patients and 21 age-matched healthy participants. RESULTS: FXS patients exhibited greater gamma frequency band power, which was correlated with social and sensory processing difficulties. Second, FXS patients showed increased spatial spreading of phase-synchronized high frequency neural activity in the gamma band. Third, we observed increased negative theta-to-gamma but decreased alpha-to-gamma band amplitude coupling, and the level of increased theta power was inversely related to the level of resting gamma power in FXS. CONCLUSIONS: Increased theta band power and coupling from frontal sources may represent a mechanism providing compensatory inhibition of high-frequency gamma band activity, potentially contributing to the widely varying level of neurophysiological and behavioral abnormalities and treatment response seen in full-mutation FXS patients. These findings extend preclinical observations and provide new mechanistic insights into brain alterations and their variability across FXS patients. Electrophysiological measures may provide useful translational biomarkers for advancing drug development and individualizing treatments for neurodevelopmental disorders with associated neuronal hyperexcitability.

Figures

Fig. 1 a Significant group differences in connectivity strength between FXS and healthy control participants based on permutation tests (p < 0.05) show increased connectivity in FXS in the gamma band across electrodes but reduced within-band connectivity in the alpha (lower and upper) and beta range. b Mean and standard error of between-electrode distances for electrode pairs showing group differences (plotted in a) in lower alpha, upper alpha, beta and gamma bands. Asterisk denotes significant differences in connectivity distances with significant group differences between bands at p < 0.05. c Bivariate scatter plots depicting the relationship between average connectivity strength (dbWPLI) and average between-electrode distance for FXS (red dots) and healthy control participants (black dots)

Fig. 3 a Scalp topographies of “global coupling” showing correlations between activity in the region showing the maximum relative power of activity in the theta, and lower and upper alpha power bands defined as the average of the power in that region of electrodes clusters (marked with *) and gamma power in all other electrodes for FXS and healthy control participants. Significant group differences are presented in the bottom row (p < 0.05, corrected), with dark blue reflecting no group difference. b Mean and standard error of correlations for all electrodes showing group differences as are plotted in A. Asterisk denotes correlations of spectral power in theta and upper alpha bands with gamma band power that are significantly different from zero based on the results of permutation analyses at p < 0.05

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.
