Have you ever wondered what happens in your brain when you lose yourself in a gripping short story? Research shows that reading fiction isn’t just a passive activity—it’s an immersive experience that engages multiple brain regions. When we read, we simulate the story in three distinct ways: motor simulation (imagining physical actions), perceptual simulation (re-enacting sensory experiences), and mental simulation (understanding characters’ inner worlds). But what are the neural substrates of these simulations? Do they follow distinct pathways, or do they converge in a specific brain region? Mak and colleagues’ (2023) study sheds light on these questions.
Study overview

Findings
Eye movement analysis showed that motor descriptions were read faster, while perceptual and mental descriptions slowed reading due to more complex cognitive demands. Furthermore, trait-level factors like empathy and transportability had a stronger influence on brain activation than state-based factors like story absorption, emphasizing the role of personality in narrative simulation.
* The supramarginal gyrus functions as a hub where multiple brain networks intersect, including the default mode network (involved in self-perception and mind-wandering) and the mentalizing network (responsible for social cognition).
