Imageless imagery in aphantasia revealed by early visual cortex decoding.
Current Biology February 3, 2025 Shuai Chang, Xinyu Zhang, Yangjianyi Cao et al.
Activity in the early visual cortex is thought to tightly couple with conscious experience, including feedback-driven mental imagery. However, in aphantasia (a complete lack of visual imagery), the state of mental imagery, what takes its place, or how any activity relates to qualia remains unknown. This study analyzed univariate (amplitude) and multivariate (decoding)...
