Fleming and Dijkstra · Cell Research
Researchers discovered that mental imagery reactivates the same sensory code as perception at the single-neuron level. This suggests that aphantasia may stem from how this shared activity is generated, modulated, or read out by the brain.
Dijkstra · Vision
The early visual cortex represents fine-grained visual details during mental imagery in a similar way to perception. This suggests that the recruitment of these areas depends on the level of visual detail required by the mental image.
Dijkstra and Fleming · Nature Communications
The brain distinguishes reality from imagination based on whether intermixed sensory signals cross a strength threshold. This suggests that sufficiently vivid mental imagery can become subjectively indistinguishable from actual perception.

Neural activation during mental imagery occurs in the reverse order of perception, with high-level areas activating before low-level ones. This confirms that imagery is a top-down process driven by feedback from the brain's hierarchy.
