**5. Conclusions**

While several brain regions in both hemispheres are involved in di fferent aspects of mental imagery, our results indicate that the right lingual gyrus and especially the left posterior medial fusiform gyrus are candidate regions for specific involvement in *visual* imagery. These regions were only a ffected in the aphantasic architect PL518 compared to non-aphantasic patients with comparable cognitive and perceptual deficits.
