Preprocessed EEG recordings during an emotional antisaccade task: A dataset comparing obsessive-compulsive disorder and healthy control groups.
Description
The EEG dataset consists of preprocessed data recorded in 30 participants without OCD (Antisaccade_control.zip) and in 31 participants with OCD (Antisaccade_OCD.zip). In the data markers of the antisaccade onset were added.

Steps to reproduce
Continuous EEG data was recorded from 64 scalp sites (actiCAP snap, Easycap GmbH, Herrsching, Germany). FCz served as a reference channel for the monopolar design of the EEG recordings. A bandpass filter was set from 0.05 to 70 Hz, and the sampling rate was 500 Hz. EEG data were analyzed in BrainVision Analyzer 2.2 (Brain Products GmbH, Gilching, Germany). First, EEG noisy channels were interpolated, and the EEG signals were referenced to an average reference. A high pass filter of 0.5 Hz (slope – 8 dB/octave), a low-pass filter at 30 Hz (slope – 8 dB/octave), and a notch filter at 50 Hz were applied. To remove eye-movement and blink-related EEG artifacts, independent component analysis (ICA) was conducted. Additionally, continuous EEG was visually inspected and manually cleared from periods with muscle and motion artifacts. Important! There is a marker "R 1" instead of a marker "S 32".
