How the brain understands pictures. The
figure is famous: a deceptively simple line drawing that at first
glance resembles a vase and, at the next, a pair of human faces in
profile. When you look at this figure, your brain must rapidly decide
what the various lines denote. Are they the outlines of the vase or the
borders of two faces? How does your brain decide? It does so in a
fraction of a second via special nerve circuits in the brain's visual
center that automatically organize information into a "whole" even as
an individual's gaze and attention are focused on only one part,
according to Johns Hopkins researchers writing in a recent issue of the
journal Neuron. [Science Blog - Science News Articles from Medicine, Space, Physics and More]
