[Eeglablist] How to interpret ERSP statistics

[장진원]

Dear all,

I'm a beginner at EEGLAB. While analyzing ERSP statistics with a paired
t-test, I have a problem determining whether there is a statistically
significant difference along a certain timeline. For example, sometimes
there are very short and small dots with p<0.05 in ERSP image. Does it also
represent significant difference? What are the criteria to insist there is
actual difference? How long range of difference is minimally required?  Or
is it totally arbitrary depending on the author?

Best wishes,
