Dear SPM experts,
I have used the group source reconstruction toolbox provided by SPM.
It worked very well, but know it's for me to interpret my results !
I have used the both type of temporal contrast (ie gaussian window and morlet wavelet) and I founded slightly different results.
I used a time windows for the inversion between 0 to 800 ms and a temporal contrast between 0 and 400 ms to highlight the different sources involved in all my process.
I am working on a langage task which is known to imply broca's and wernicke's area and it is what I found !
with the gaussian window I found Broca's area and with the series of wavelet I found broca's and Wernicke's areas. both type of contrast are strongly significant even with FWE correction.
And know I have to interpret it!
Can I say that using a gaussian windows I highlight more continuous activation whereas using a series of wavelet I will more highlight transient activation in upper frequency band?
should I refine my study and doing it in the different well known frequency band?
thank you for your attention,
bests regards,
Gaetan Yvert
