Aphantasia links to altered brain connectivity, Paris research shows

Researchers have found a potential link between aphantasia, the inability to visualize mental images, and altered brain connectivity. This discovery was made using high-resolution fMRI scans. The study revealed that individuals with aphantasia showed reduced functional connectivity in brain regions associated with visual imagery, even when those areas were activated. This suggests less efficient communication between brain networks involved in perception and attention. This research, published in Cortex, utilized advanced imaging techniques to study the neural basis of visual imagery. It offers insights into how the brain processes visual information and may help explain the variability in how people experience the world.
