Hello,
I'm wondering if anyone has experience with the above. I'd like to do two sets of analyses
on sources of the induced EEG response: one response locked, where the power in the time-
frequency window of interest is expressed as a change from a pre-target-onset baseline, as
well as a response-locked analysis, where the power is also expressed with respect to a
pre-target-onset baseline. I understand that it's recommended to restrict the reconstruction
time range to the epoch of interest; this is straightforward for target locked analyses where
the time from the start of baseline to the end of the epoch of interest is the same across
trials, but it doesn't seem so easy for response-locked. One thing I thought to do was four
reconstructions (one for each target- and response-locked window of interest as well as for
the corresponding baselines) with four separate time-windows. Another was to play with
the code and use different time windows for each trial of the response-locked analysis.
If anyone has additional suggestions or good reasons why I should go with one approach
over the other, it would be greatly appreciated.
Best
Kevin
