has been proposed for use in the diagnosis of various psychiatric disorders. Clinical studies have demonstrated distinctive forms of brain electrical activity in psychiatric conditions including attention deficit disorder, schizophrenia, major depression, and obsessive-compulsive disorder. However, ...
Full size image 3.6 EEG Signal Preprocessing and Feature Extraction The pre-processing stage of the raw EEG data was realized using Matlab v. R2022a. A digital filtering was applied in order to filter out the power line noise and extract the frequency bands of interest. Specifically, a 50 Hz...
The selected EEG data was collected by the University Medical Center of Freiburg, in Germany, from patients containing seizures localized in the temporal lobe, the most usual form of focal epilepsy27. The data consists of EEG scalp recordings acquired during pre-surgical monitoring. It covers 19 ...
Full size image EEG electrodes are digitized in the same head coordinate frame along with the other digitized points because they are on the scalp. Thus, EEG source imaging involves a combination of only two coordinate systems—the head coordinate system and the MRI coordinate system. Earlier stud...

Full size image Relationship Between Resting-State Microstate 4 GEV and CBQ-SF Effortful Control Scores (Model 4; n = 87) The addition of resting-state microstate 4 GEV to sex was not associated with a statistically significant increment to the proportion of variation in CBQ-SF effortful...
Full size image Statistical methods Mixed-effects linear regression models using Stata v.14.2 (StataCorp, TX) were used to assess differences in power associated with age (continuous, in years), autism diagnosis, and sex. Nested random effects were included for site and family, to account for ...
