Strikingly simple 'dial' in the brain may help it distinguish imagination from reality

Scientists have discovered brain mechanisms distinguishing reality from imagination. The fusiform gyrus, active during perception and imagination, determines reality based on signal strength. When activity crosses a threshold, the brain interprets it as real. This finding may help understand conditions like schizophrenia. The study used fMRI scans and visual experiments, but further research with complex stimuli is needed for a complete understanding.
