    Binocular rivalry reveals an out-of-equilibrium neural dynamics suited for decision-making

    Robin Cao et al.
    The statistics of binocular rivalry at different combinations of image contrast is reproduced quantitatively by competing out-of-equilibrium populations of independent neural assemblies with idealized attractor dynamics.

    Attention periodically samples competing stimuli during binocular rivalry

    Matthew J Davidson et al.
    A combined behavioural and electroencephalographic approach investigating the covert allocation of attention shows evidence for distributed periodic sampling away from a conscious visual image.

    Body ownership promotes visual awareness

    Björn van der Hoort et al.
    Inducing illusory ownership of a fake hand increases the perceptual dominance of that hand during binocular rivalry.

    A new no-report paradigm reveals that face cells encode both consciously perceived and suppressed stimuli

    Janis Karan Hesse, Doris Y Tsao
    Conscious visual percepts are encoded by face patches in the absence of report, can be decoded from population recordings, and are multiplexed with the veridical physical stimulus.

    Separable pupillary signatures of perception and action during perceptual multistability

    Jan W Brascamp et al.
    When conscious visual perception changes, the observer's pupils simultaneously signal the accompanying change in visual cortical representation, and specific neuromodulatory activity that helps translate the altered visual experience into behavior.

    Response to short-term deprivation of the human adult visual cortex measured with 7T BOLD

    Paola Binda et al.
    Two hour deprivation of vision in one eye transiently boosts the representation of the deprived eye (suppressing the non-deprived eye) in adult human V1 and along the ventral pathway.

    Sensory dynamics of visual hallucinations in the normal population

    Joel Pearson et al.
    A new method for inducing, measuring and modelling visual hallucinations in healthy people reveals that hallucinations share common underlying mechanisms with normal sensory perception.

    Humans treat unreliable filled-in percepts as more real than veridical ones

    Benedikt V Ehinger et al.
    In a forced decision between two identical percepts, subjects preferentially rely on inferred internally generated over veridically seen percepts.

    The SSVEP tracks attention, not consciousness, during perceptual filling-in

    Matthew J Davidson et al.
    The strength of frequency-tagged neural activity during perceptual filling anti-correlates with the contents of consciousness, yet positively correlates with a neural measure of attention, dissociating these often confounded brain processes.

    Cortical excitability controls the strength of mental imagery

    Rebecca Keogh et al.
    Visual and prefrontal cortex excitability predict individual differences in visual imagery strength, and modulating excitability in these cortical regions causally alters the strength of visual imagery.
