Compute sources in deep cerebral structures : DBA tutorial
This tutorial explains step-by-step how to use the DBA (Deep Brain Activity) functionality, useful to assess subcortical source localization.
Import Database
To follow through the tutorial, a dataset can be downloaded *here*.
It contains MEG resting-state recordings of 7 subjects under 2 conditions, eyes-open (YO) and eyes-closed (YF). For each subject and under each condition, 20 runs of 15 seconds are included in the dataset.
The dataset is already in Brainstorm format and simply needs to be loaded via File > Load Protocol. LoadProtocol
In the following steps, you
Select deep structures
Compute Noise Covariance matrix
Compute source activity
Visualize activity
