When the mind’s eye goes dim: what aphantasia reveals about imagination
Most people can visualize details from daily life, but about 4% have little to no mental imagery (aphantasia). The article traces its discovery, how researchers measure imagery (e.g., binocular rivalry) and brain activity, and suggests aphantasia may involve both lack of conscious access and difficulty in voluntary generation. Despite variability and possible genetic links, many with aphantasia function normally in memory and creativity, making it a valuable window into how the brain constructs inner experiences and consciousness.
