Functions Suppressing and Facilitating MentalImagery Generation and the Processes that Generate Uncontrollable Imagery

Abstract

This study investigated mechanisms suppressing the generation of visual imagery and those that suppress visual perceptual processing without competing with visual imagery generation. The brain region that plays a role in the former function was identified. Moreover, it has been suggested that this is process is mental functions. Furthermore, it has been reported that the performance decreases in concurrent visual perceptual tasks as a result of visual imagery generation, compared to concurrent visual perceptual processing, possible because of suppressing visual perceptual processing during visual imagery generation. Finally, we have discussed the relationship between these two functions and uncontrollable mental imagery observed in clinical situations.
