Information about funding sources that supported the collection of the data: Data collection was supported by National Institutes of Health (grant number: R01 EY02301) 7. Overview of the data (abstract): The dataset comprises 85 (84 valid EEG records) participants from a study on binocular rivalry. EEG signals were recorded from 34 channels in the 10/20 system, and preprocessed with standard methods. Twelve 120-s runs of a binocular rivalry task were acquired for each participant, during which they were presented with orthogonal (± 45°) gray scale gratings, one to each eye, as illustrated in the upper left box in Figure 1A. One grating flickered at 14.4 Hz and the other at 18.0 Hz in each run, counterbalanced between eyes across runs. Participants were instructed to press one of three buttons, indicating a dominant percept of “tilt left”, “tilt right”, or a mixed percept, whenever their perception changed. They were asked to report dominance once one grating filled &gt;90% of the stimulus field and mixed otherwise. -------------------------- SHARING/ACCESS INFORMATION -------------------------- 1.
