In the original article, there was an error. The abstract states that we compared 26 FXS participants with 7 neurotypical controls. This is incorrect. As correctly stated in the methods and result sections, we compared 26 FXS participants to 77 neurotypical controls.

A correction has been made to Methods section of the Abstract.

Methods: In this study, resting-state EEG power, including alpha peak frequency (APF) and theta/beta ratio (TBR), as well as signal complexity using multi-scale entropy (MSE) were compared between 26 FXS participants (ages 5–28 years), and 77 neurotypical (NT) controls with a similar age distribution. Subsequently a replication study was carried out, comparing our cohort to 19 FXS participants independently recorded at a different site.

The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
