‘figure’ stimuli When a camouflaged ‘figure’ comprised of disconnected line segments moves, it spontaneously segregates from the background [1]. Following motion offset, the form percept persists for up to several seconds when ‘figure’ remains—if removed, the percept of the figure decays more abruptly. The persistence of form is evident in the fMRI activity of human lateral occipital cortex (LO) [2].
