[Eeglablist] Question about ICA components

Tue Oct 23 11:57:16 PDT 2012

Hello,

Since you are new to ICA,
I would suggest that you take the time to take a very close look and go
through
the following resources. Good luck with your process and learning!

*a recent chapter from Dr.Makeig:*
http://tdlc.ucsd.edu/research/publications/MakeigOnton_ERP_2009.pdf

* the EEGLAB tutorial and use the sample data there. *
http://sccn.ucsd.edu/eeglab/eeglabtut.html

*the EEGLAB workshop videos and powerpoint slides:*
http://sccn.ucsd.edu/wiki/Online_EEGLAB_Workshop

*the articles from Dr.Makeig that have used ICA in the past,*
http://sccn.ucsd.edu/~scott/

and there are many articles that you can search for in Google Scholar under
"ICA and EEG"
I have listed some titles below, you can easily find the links via google
scholar.
in some cases below, I have included the link.
