| − | * You have jitter between trials in ERP experiment (i.e. random value of ±200ms). Some further guidelines about paradigm creation can be found here: (Rusiniak et al., 2013a).

| − | * The subject movement is limited to minimum.
| + | |
| − | * Electrode to skin impedance is as low as possible.
| + | |
| − | * EEG-fMRI recording session was long enough to allow for proper artifact creation. Usually experiment should last at least 6 minutes.
| + | |
| − | * Especially for first few registrations repeat the experiment outside of the bore to compare results.

| − | The recommended pipeline of processing EEG data registered during fMRI session looks as follows:

| − | '''Please note that some steps are grouped with colors:'''
| + | |
| − | * orange color indicate steps that are part of typical processing of ERP data.
| + | |
| − | * blue color indicate optional, yet strongly recommended EEG-MRI data co-registration.
| + | |
| − | * yellow color marks the steps related to fMRI gradient artifact removal
| + | |
| − | * green steps are reserved for BCG/blink artifact correction
| + | |
| − | * violet color indicate steps for time frequency analysis. Here also information about rejected epochs is provided for averaging.
