Researchers at Stanford are subjecting Literature PhD students to fMRI scans while they read:
During a series of ongoing experiments, functional magnetic resonance images track blood flow in the brains of subjects as they read excerpts of a Jane Austen novel. Experiment participants are first asked to leisurely skim a passage as they might do in a bookstore, and then to read more closely, as they would while studying for an exam.
Phillips said the global increase in blood flow during close reading suggests that "paying attention to literary texts requires the coordination of multiple complex cognitive functions." Blood flow also increased during pleasure reading, but in different areas of the brain. Phillips suggested that each style of reading may create distinct patterns in the brain that are "far more complex than just work and play."
Next I want them to study blood flow for subjects reading even more genres of fiction, such as erotica.
