Greetings MNE community,
I have an ERP dataset with 100 trials, with data epoched 1 second before
and 1 second around the event at time 0.
In sensor-space, I have conducted a time-frequency analysis using the
entire 2 second window length across trials with frequencies of interest
being between 4 - 45 Hz.
I then followed this tutorial to find wPLI connectivity, using F5 as my
channel of interest.
However, my time window of interest in connectivity is shortly after the
event, specifically from 0.02 s to 0.08 s. Using this time window, and
comparing wPLI measures in a pre-post fashion, I have a statistical
significant effect between in the alpha band (9 - 12 Hz).
Ideally, I would like to know the source-level connectivity information of
this significant finding.
My question is, because of the narrow time window of interest, can wPLI
measures at the source level be calculated with time-resolved information?
Is what I'm hoping to do (or have done thus far) even appropriate?
Many thanks in advance.
