When sensory information about a perceived stimulus is ambiguous, the visual system forms multiple distinct interpretations of said stimulus. Multistable perception occurs when perception of the stimulus alternates between interpretations over time.
Multistable perception may arise from interactions between lower-order and higher order brain processes. Lower order brain processes are involved in basic mental functions such as attention and perception, whereas higher order brain processes are involved in complex mental functions such as reasoning and abstract thinking.
The review discusses how brain processes underlying different levels of visual processing (low-level sensory, intermediate extrastriate, and high level frontoparietal) interact with one another to produce visual multistable phenomena such as binocular rivalry.
