<div>Dear EEGLAB users,<br></div><div><br></div><div>I have a question about the ICA components. I am analyzing EEG data generated from 32 channels. I obtained the ICA components for that data (31 IC components). I am interested in analyzing the data from the visual cortex. My question is will each ICA component represent data from each channel. I have plotted IC1 properties will it represent channel 1 properties and please let me know where can i get some information about Independent Component Analysis.</div>
<div><br></div><div>thank you,</div><div>Chaitanya</div>
