Super visc high viscosity electrolyte gel

EEG was recorded using 64 actiCap slim active electrodes (Brain Products GmbH, Gilching, Germany), with 62 electrodes embedded within an elastic cap (Easycap GmbH, Herrsching, Germany). This included the reference positioned at CPz and ground at AFz. The remaining electrodes were the left and right electrooculography (EOG) electrodes (placed below and above each eye, respectively), and left and right electromyography (EMG) electrodes (placed on the chin). Fig. S2 shows the EEG electrodes layout. Elefix EEG-electrode paste (Nihon Kohden, Tokyo, Japan) was used for stable electrode attachment and Super-Visc high viscosity electrolyte gel (Easycap GmbH) was inserted into (which was not certified by peer review) is the author/funder.

To amplify the signal, we used either two BrainAmp MR plus EEG amplifiers or a LiveAmp wireless amplifier (all from Brain Products GmbH). Signals were recorded using BrainVision Recorder software (Brain Products GmbH).
