[Eeglablist] How to calculate the global mean field power (GMFP)

[大江健吾]

Dear all,

I am conducting a TMS-EEG analysis. I am going to calculate  the global
mean field power (GMFP; Lehmann and Skrandies, 1980) from the multichannel
average signals as follows:[image: image.png]

 I am having difficulty computing a comparison between conditions 'A' and
'B' during 300 - 400 msec intervals. How should I write the MATLAB scripts?

Kind regards.
