Virtually all neuroscience research on visual mental imagery—including my own!—may rest on false assumptions. Time to rethink the foundations. New paper with Margherita Arcangeli in @Brain1878. @aphantasia

Differences: 1. although aphantasics encoded stimulus content during imagery, these representations differed from ones elicited by perception. 2.aphantasics exhibited reduced connectivity between anterior visual areas and the OFC patches (exert top-down modulation in visualisers)

A follow-up 7T fMRI study on face- and colour-processing systems in aphantasia revealed normal ventral temporal activity. see 🧵https://bsky.app/profile/jianghaoliu.bsky.social/post/3lp2spzhjvs2z

📢"Aphantasia as a functional disconnection"! in TICS
A disconnection between the Fusiform Imagery Node (FIN) & the left PFC may explain retained memory for objects, despite lacking subjective imagery in aphantasics.
left PFC, awareness, attention network...🧵

(1/9)Thrilled to share our new preprint🧠Using 7T fMRI, we report the presence of face-, color- and word-specific patches in the human #orbitofrontal cortex (OFC), which form continuous functional gradients with VOTC patches.
