Correlation with sensor

I computed the inverse EEG problem to find the active sources using dSPM.
I plotted scouts using this option: Correlation with sensor.

I want to know if there is some relationship between these sources and ICA method.
Also, I'd like to clarify what you mean by "correlation" here.
Many thanks!

Not at all.

Also, I'd like to clarify what you mean by "correlation" here.

Correlation coefficients between one source signal and one sensor signal, as computed with Matlab's corrcoef. Please see directly in the code for further details:


Okay, thank you very much for your help!
