He wrote that the "human mind is capable of excitement without the application of gross  and violent stimulants ". And it appears that simply reading those words by William Wordsworth proves his point. Researchers at the University of Liverpool found the works of Shakespeare and Wordsworth and the like had a beneficial effect on the mind, lifting the readers' spirits by catching their attention and leading to moments of self-reflection. Using equipment, they examined the brain activity of volunteers as they read pieces of classical English literature both in their original form and in a more simplified, modern translation. And, according to the Sunday Telegraph, the experiment showed the more "challenging" works set off far more electrical activity in the brain than the ordinary versions. The research also found poetry, in particular, increased activity in the right hemisphere   of the brain, an area concerned with "autobiographical memory", which helped the reader to reflect on and reevaluate their own experiences in light of what they had read. The academics said this meant the classics were more useful than self-help books. The brain responses of 30 volunteers was monitored in the first part of the research as they read Shakespeare in its original and "modern" form. In one example, volunteers read a line from King Lear, "A father and a gracious  aged man: him have you madded ", before reading the simpler "A father and a gracious aged man: him you have enraged ". Shakespeare's use of the adjective "mad" as a verb caused a higher level of brain activity than the straightforward translation. "Reading classics is not just a matter of style. It is a matter of deep versions of experience that promotes the cognitive  ability," said Prof Davis, who will present the findings at the North of England education conference in Sheffield this week. Which of the following sets off the most electrical activity in the brain?
Reading nursery rhymes. Reading self-help books. Reading adapted version of King Lear. Reading Shakespeare's sonnets  in Middle English.
