SSVEP-EEG data collection using Emotiv EPOC

The data acquisition process begins with capturing EEG signals from 20 healthy skilled volunteers who gave their written consent before performing the experiments. Each volunteer was asked to repeat an experiment for 10 times at different frequencies; each experiment was trigger by a visual stimulus.

Each volunteer performed an experiment for each of the 10 visual stimuli frequencies (7, 9, 11 and 13). In each experiment the EEG signals generated in the 2 electrodes (LO, RO) of the occipital area was simultaneously recorded. It is important to note that the data acquisition equipment has a sampling rate of 128 samples per second, allowing to acquire 2500 samples, considering that each task has a duration of 19.5 seconds.
