Newswise — PITTSBURGH--Visual hallucinations ... everyone has heard of them, and many people have experienced the sensation of "seeing" something that isn't there. But studying the phenomenon of hallucinations is difficult: they are irregular, transitory, and highly personal--only the person experiencing the hallucination knows what he or she is seeing, and representations of what's being seen are limited to verbal descriptions or drawings.
A research team of Bard Ermentrout from the University of Pittsburgh's Kenneth P. Dietrich School of Arts and Sciences and Joel Pearson from The University of New South Wales in Australia have come up with a way to create hallucinations that could make them easier to be studied objectively, potentially leading to new treatment methods. Ermentrout and Pearson outline their discovery in a paper, "Sensory dynamics of visual hallucinations in the normal population," which was published in the Oct.11 edition of eLife.
