WebfMRI provides access to the whole brain. This is necessary to measure and predict advertising effects. After all, advertising does its work in deeper brain areas where emotions are stored and activated. Crucially, emotions determine consumer behaviour, such as making a purchase. These emotions are largely unconscious to consumers themselves.
