From: Remote collection of electrophysiological data with brain wearables: opportunities and challenges
Examples of raw EEG data collected from consumer-grade wearables. (A) Raw EEG data collected from a consumer-grade 4-electrode Muse 2 wearable. X axis represents time and Y axis shows electrode labels. AF and TP are labels for the data collected by anterior-frontal and temporoparietal electrodes, respectively. The scale is shown by the red line representing 160 microvolts of amplitude. Large spikes are likely to be a result of ocular and muscular artifacts. (B) Raw EEG data collected from a research-grade 14-electrode EPOC X wearable. Time is shown on the X axis and electrode labels on the Y axis (international 10–20 system)
