It represents neither amplitude nor frequency spectrum. These maps correspond to the independent components of your data. Refer to Independent component analysis (Basic reference for use with EEGLAB available on EEGLAB website)<br>

Dear All,<br>I have basic doubts in component maps.<br>Is it the component 2-D maps which is obtained in <b> plot>component maps>2-D maps</b> is representing the<b> amplitude spectrum</b> of various channels which are is fed in?.or it represents the <b>frequency spectrum</b>.<br>
and <br>say,<br>Suppose
I import a 16 channel data with channels namely Fp2 , F4, C4,
.............and so on, then component maps obtained are 1,
2,3.............<br><b>Can I consider that the 2-D map 1 is corresponding to</b><b> Fp2 and </b><b>map 2 to </b><b>F4 etc...</b>?<br>
please help.<br>Regards<br><font color="#888888"><font color="#888888">Thomas George</font>
