We acquired EEG using SynAmps amplifiers and Neuroscan data acquisition software (Compumedics). Sixty-one electrodes were distributed across the scalp using the international 10-10 positioning system. Data were referenced to the left mastoid during acquisition, and we included a right mastoid measurement to derive an average mastoid reference offline. The ground was positioned on the left upper arm. We concurrently collected vertical and horizontal electrooculography (EOG), using a bipolar montage with electrodes to the side of each eye, and above and below the left eye. During acquisition, data were filtered between 0.1 and 200 Hz, digitized at 1000 Hz, and stored for offline analysis. Electrode impedance was aimed to be below 5 kiloohm and was at least below 10 kiloohm.
Neuroscan data acquisition software
Manufactured by Compumedics
Neuroscan data acquisition software is a comprehensive solution for recording and analyzing neurophysiological data. It provides a reliable and efficient platform for acquiring high-quality data from various neuroimaging modalities, including electroencephalography (EEG), event-related potentials (ERPs), and more. The software offers a user-friendly interface and advanced tools for data management, processing, and visualization.

EEG data was collected at a sampling rate of 1000 Hz with Synamps amplifiers and Neuroscan data acquisition software (Compumedics) and 61 scalp electrodes following the 10–20 layout. Additionally, bipolar electrodes were placed below and above the right eye and on the temples to measure eyeblinks as well as horizontal and vertical eye movements (HEOG and VEOG channels). A ground electrode was attached to the left elbow bone. The EEG signal was referenced to the left mastoid but later re-referenced to the average of left and right mastoids. Impedances of electrodes were kept below 15 kΩ.

We acquired EEG using Synamps amplifiers and Neuroscan data acquisition software (Compumedics). Sixty-one electrodes were distributed across the scalp using the international 10–10 positioning system. The left mastoid was used as the active reference, and we included a right mastoid measurement to derive an average mastoid reference offline. The ground was placed on the left upper arm. Additionally, vertical and horizontal electro-oculography (EOG) electrodes were used to monitor for eye blinks and eye movements. During acquisition, data were low-pass filtered by an antialiasing filter (250 Hz cutoff), digitized at 1000 Hz, and stored for offline analysis.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
