New findings raise questions about whether variations or alterations in this system could lead to hallucinations, invasive thoughts or dreaming.

Brain scans don't have high enough resolution for neuroscientists to discern differences in how the networks are used.

Other hypothesis suggests that the same pathways in the brain code for both imagination and perception, but imagination is just a weaker form of perception.
