You can find information to flip left-right EEG channels:

Flipping BioSemi EEG layout

Hello Brainstorm community, I am currently using ICBM152 > BioSemi > BioSemi 64 10-10 for my EEG montage. However, due to my test population who are unilaterally deaf due to surgery, during analysis, I need to flip the electrodes to one hemisphere for all participants consistently for averaging. Flipping the electrodes consistently to one hemisphere is necessary otherwise the neural plasticity effects of unilateral deafness due to surgery will be averaged out as half of my participants have l…

In the case of MEG, you should not do any source modeling after flipping the sensors left-right.

For source data: what would you do with this exactly?
