37. EEG MRI analysis

Structural MRI

Reconstruct brain structure using FreeSurfer and T1-weighted MRI (MPRAGE sequence) data. Details are here.

fMRI

Follow the instruction here for fMRI data pre-processing, including the following

• convert meas.dat into Matlab mat files
• register between fMRI and structural MRI
• prepare fMRI data on brain surfaces

The fMRI analysis using Genearal Linear Model can be found here.

Register between anatomical MRI and fMRI

1. Using only SMS-InI data

1.a. Manually coregister between fMRI and anatomical MRI (FreeSurfer recon)

1.b. Run bb_register to get more accurate registration

2. Using EPI data with sliced matched with SMS-InI reference scans

2.a. Prepare EPI data

2.b. Manually coregister between fMRI and anatomical MRI (FreeSurfer recon)

2.c. Run bb_register to get more accurate registration

EEG

EEG pre-processing includes

• suppress gradient and pulse artifacts.
• calculate event-related potentials (for event-related design).

To do EEG source anaylysis, follow the procedure here.
