<div dir="ltr"><div>Hello,</div>
<div> </div>
<div>I had EEG data and it had been processed with ICA for EOG signal rejection. </div>
<div>And I am interested in high frequency activities like gamma band activity, including both power and phase.</div>
<div>I wonder whether it is effective that high frequency(more than 30Hz) is analyzed after ICA process.</div>
<div> </div>
<div>My EEG data was processed with 'runica' function.</div>
<div>Can I perform gamma analysis with this data? </div>
<div> </div>
<div>Sincerely,</div>
