Here’s an interesting article about how our brains respond to stories, proving that good stories actually have a physiological effect on us.
When subjects read this passage and several others in an fMRI machine, researchers were able to observe which parts of their brain were activated as the subjects read different elements. Depending on what was happening in each sentence, quite different brain activation patterns were observed:
For example, a particular area of the brain ramped up when readers were thinking about intent and goal-directed action, but not meaningless motion. Motor neurons flashed when characters were grasping objects, and neurons involved in eye movement activated when characters were navigating their world.
Readers are far from passive consumers of words and stories. Indeed, it appears that we dynamically activate real-world scripts that help us to comprehend a narrative—and those active scripts in turn enrich the story beyond its mere words and sentences. In this way, reading is much like remembering or imagining a vivid event.
