Kronemer and colleagues · Neuroscience of Consciousness
Researchers found that visual imagery vividness positively correlates with the contrast and sharpness of negative afterimages. This suggests that afterimages and mental imagery may share top-down neural mechanisms in the brain.
Sulfaro, Robinson and Carlson · Neuroscience of Consciousness
Researchers found that sensory input competes with mental imagery in a hierarchical neural network, preventing thoughts from dominating low-level sensory regions. This explains why mental imagery feels less vivid than real perception and how aphantasia arises from overweighted bottom-up signals.
