EEG was recorded in an acoustically shielded room with a BrainAmp amplifier system (Brain Products, Gilching, Germany) at a sampling rate of 1000 Hz. A 32-electrode cap was used, and electrodes were placed in accordance with the international 10/20 system. All electrode impedances were ensured to be <25 kΩ. To record the electrooculogram, electrodes 28 and 32 were placed beside and above the left eye. For online recording, the FCz was used as a reference electrode. The audio stimuli were presented at a 44.1 kHz sample rate during the EEG recording using the Presentation software (Neurobehavioral System, Berkeley, CA). All participants were instructed to ignore the audio stimuli and watch a subtitled movie with muted audio (more details available in Petersen et al., 2020 (link)). The duration of the EEG recording was approximately 35 min.

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.
