Real-time EEG and Magnetometer Data

<p>Harmonic Synchrony Subjects.zip</p> <p>Dataset to recreate portions of Figures 7 and 8.</p> <p> </p> <p>These datasets are MATLAB workspaces which contain simultaneous measurements of the earth-ionosphere ultra-low frequency (ULF) activity and 19 channel quantitative electroencephalographs for 3 subjects.  Subjects marked local indicate that ULF activity was monitored simultaneously in Sudbury, Canada while non-local indicates that the e-field measured in Cumiana, Italy.  See links below for live data from both stations.</p> <p>The variables in the workspaces are:</p> <p><strong>1) Raw_19ChanEEG_Mag_Refiltered</strong></p> <p>Contains the raw data (19 brain leads + magnetometer) which has been filtered with <em>eegfiltfft.m</em> between 1.5 and 40 Hz.  First 19 columns indicate brain channels</p> <p>1.
