Now we’re seeing that something may also be happening biologically.’He claims that the neural changes are not immediate reactions as they linger five days after the participants completed the novel.Professor Berns said: ‘It remains an open question how long these neural changes might last.’‘But the fact that we’re detecting them over a few days for a randomly assigned novel suggests that your favorite novels could certainly have a bigger and longer-lasting effect on the biology of your brain.’(Daily Mail)ANN.Az
