  1. Multistable phenomena: Changing views in perception.David A. Leopold & Nikos K. Logothetis - 1999 - Trends in Cognitive Sciences 3 (7):254-264.
    Traditional explanations of multistable visual phenomena (e.g. ambiguous figures, perceptual rivalry) suggest that the basis for spontaneous reversals in perception lies in antagonistic connectivity within the visual system. In this review, we suggest an alternative, albeit speculative, explanation for visual multistability – that spontaneous alternations reflect responses to active, programmed events initiated by brain areas that integrate sensory and non-sensory information to coordinate a diversity of behaviors. Much evidence suggests that perceptual reversals are themselves more closely related to the expression (...)

  7. Stable perception of visually ambiguous patterns.David A. Leopold, Melanie Wilke, Alexander Maier & Nikos K. Logothetis - 2002 - Nature Neuroscience 5 (6):605-609.
    Correspondence should be addressed to David A. Leopold [email protected] the viewing of certain patterns, widely known as ambiguous or puzzle figures, perception lapses into a sequence of spontaneous alternations, switching every few seconds between two or more visual interpretations of the stimulus. Although their nature and origin remain topics of debate, these stochastic switches are generally thought to be the automatic and inevitable consequence of viewing a pattern without a unique solution. We report here that in humans such perceptual alternations (...)

    Measuring subjective visual perception in the nonhuman primate.David A. Leopold, Alexander Maier & Nikos K. Logothetis - 2003 - Journal of Consciousness Studies 10 (9-10):115-130.
    Understanding how activity in the brain leads to a subjective percept is of great interest to philosophers and neuroscientists alike. In the last years, neurophysiological experiments have approached this problem directly by measuring neural signals in animals as they experience well-defined visual percepts. Stimuli in these studies are often inherently ambiguous, and thus rely upon the subjective report, generally from trained monkeys, to provide a measure of perception. By correlating activity levels in the brain to this report, one can speculate (...)

    Perception of temporally interleaved ambiguous patterns.Alexander Maier, Melanie Wilke, Nikos K. Logothetis & David A. Leopold - 2003 - Current Biology.
    Background: Continuous viewing of ambiguous patterns is characterized by wavering perception that alternates between two or more equally valid visual solutions. However, when such patterns are viewed intermittently, either by repetitive presentation or by periodic closing of the eyes, perception can become locked or "frozen" in one configuration for several minutes at a time. One aspect of this stabilization is the possible existence of a perceptual memory that persists during periods in which the ambiguous stimulus is absent. Here, we use (...)
