An ambiguous figure such as the Necker cube causes spontaneous perceptual switching
(SPS). The mechanism of SPS in multistable perception has not yet been determined …

When ambiguous visual stimuli are being looked at, perception alternates spontaneously
between two competing interpretations of the same sensory input. One major issue in …

Cognitive flexibility is critical for humans living in complex societies with ever-growing
multitasking demands. Yet the low-frequency neural dynamics of distinct task-specific and …

To what extent are attention-related brain areas involved in monitoring versus controlling
incoming perceptual information? Ambiguous figures such as the Necker cube provide an …

Ambiguous figures are visual stimuli that may be perceived in multistable interpretations.
The role of attention in modulating perceptual reversals of ambiguous stimuli is not clear. We …

Reversible figures, such as the Necker cube, make up a well-known class of visual
phenomena in which an invariant stimulus pattern gives rise to at least two different …

Electrophysiological data measured by electroencephalography and
magnetoencephalography (MEG) are widely used to investigate human brain activity in …

While viewing ambiguous figures, such as the Necker cube, the available perceptual
interpretations alternate with one another. The role of higher level mechanisms in such …

Perception of ambiguous figures is unstable and alternates repeatedly between possible
interpretations. Some approaches to explaining this phenomenon have, so far, assumed low …

OBJECTIVE: The aim of this work was to study the oscillatory changes during target and
distractor stimuli processing. We focused mainly on responses after distractor stimuli in the …
