 The ability for drugs and medications to induce synesthetic experiences in non-synesthetic people is evidence for this theory. It's possible that certain drugs manipulate these connections to allow for the feedforwarding of the inducer to cause the feedback activation of the concurrent. Often, congenital (people born with synesthesia) synesthetic experiences are usually usually very generic, of just color and/or movement. But when psychedelics (drug induced synesthetes) have an experience, it is usually complex. Psychedelics often see animals or complex scenes. The ability for drugs and medications to induce synesthetic experiences in non-synesthetic people is evidence for this theory.

-In many studies involving color -> grapheme synesthesia,​ in addition to the V4 area being activated, the anterior lingual gyrus and the intraparietal sulcus regions were activated as well. Since the intraparietal sulcus is responsible for multisensory processing in the brain, this adds support for this theory and re-entrant processing as well.+In many studies involving ​[[different_types_of_synesthesia|color -> grapheme synesthesia]], in addition to the [[definitions|V4]] area being activated, the [[definitions|anterior lingual gyrus]] and the [[definitions|intraparietal sulcus regions]] were activated as well.
