Poetry and the Brain
Poetry holds a certain sway over emotions and memories. Often times a stanza or a certain phrase from a particular poem can remind someone of a certain moment, a specific emotion, a person, or a period of time.
The brain responds to poetry in an interesting way. According to a study at the University of Exeter, the brain responds to poetry similar to how it responds to music. Areas of the brain associated with memory were much more active than areas associated with language and interpretation of language.
