The relationship between the visual evoked potential and the gamma band investigated by blind and semi-blind methods

► ICA and FSS are able to extract sources specifically related to the VEP/P100 and GBA. ► Localisation and frequency analyses show co-dependencies between VEP/P100 and GBA. ► Trial by trial induced GBA covaries with VEP amplitude. ► VEP and GBA may be generated by the same neuronal populations. ► VEP and GBA relationship may underlie the relationship between VEP and BOLD.
