London: Researchers have suggested that reading a novel can trigger actual, measurable changes in the brain that could remain for at least five days after reading.
Lead author and the director of Emory's Center for Neuropolicy, Gregory Berns ' study focused on the lingering neural effects of reading a narrative. Twenty-one Emory undergraduates participated in the experiment, which was conducted over 19 consecutive days.
All of the study subjects read the same novel, "Pompeii," a 2003 thriller by Robert Harris that is based on the real-life eruption of Mount Vesuvius in ancient Italy.
The researchers chose the book due to its page-turning plot. "It depicts true events in a fictional and dramatic way," Berns says. "It was important to us that the book had a strong narrative line."
For the first five days, the participants came in each morning for a base-line fMRI scan of their brains in a resting state. Then they were given nine sections of the novel, about 30 pages each, over a nine-day period.
They were asked to read the assigned section in the evening, and come in the following morning. After taking a quiz to ensure they had finished the assigned reading, the participants underwent an fMRI scan of their brain in a non-reading, resting state.
After completing all nine sections of the novel, the participants returned for five more mornings to undergo additional scans in a resting state.
The results showed heightened connectivity in the left temporal cortex, an area of the brain associated with receptivity for language, on the mornings following the reading assignments.
The study has been published in the journal Brain Connectivity.
