Brain sets sights on mind’s eye

Like a private movie screen showing personalized films, each person’s mind’s eye generates

a flow of imaginary visual scenes. These internal performances are inspired by a variety of

sources, from a riveting mystery novel to memories of last summer’s Olympics.

A new study by neuroscientists lends support to the notion that at least some of the brain

regions involved in visual perception of the external world animate the mind’s eye as well.
