Hi eeglabbers,<br><br>I sometimes get ICs with extremely similar topographies and time courses, like on <a href="http://oszilla.hgs.hu-berlin.de/public/Similar_ICs.PNG">this slide</a>.<br>I know that ICA returns independent components.<br>
Does that not mean that they should not look the same?<br>I know the components are independent in a statistical sense, which is not
the same as uncorrelated, but still. I'm a bit surprised. What do these two components mean if they cancel one another? well, do they?<br><br>Sorry if my question is naive, but what is happening?<br><br>The data is <a href="http://oszilla.hgs.hu-berlin.de/public/Similar_ICs.mat">here</a>.<br>
<br>Best,<br>Max<br>
