Intrinsic coupling constitutes a key feature of ongoing brain activity, which exhibits rich
spatiotemporal patterning and contains information that influences cognitive processing. We …

It has been fifty years since Levelt's monograph On Binocular Rivalry (1965) was published,
but its four propositions that describe the relation between stimulus strength and the …

Sometimes, perception fluctuates spontaneously between two distinct interpretations of a
constant sensory input. These bistable perceptual phenomena provide a unique window …

The ability to read a page of text or recognize a person's face depends on category-selective
visual regions in ventral temporal cortex (VTC). To understand how these regions mediate …

Abstract Changes in pupil size at constant light levels reflect the activity of neuromodulatory
brainstem centers that control global brain state. These endogenously driven pupil dynamics …

Brain activity fluctuates continuously, even in the absence of changes in sensory input or
motor output. These intrinsic activity fluctuations are correlated across brain regions and are …

The ascending modulatory systems of the brain stem are powerful regulators of global brain
state. Disturbances of these systems are implicated in several major neuropsychiatric …

Conscious perception sometimes fluctuates strongly, even when the sensory input is
constant. For example, in motion-induced blindness (MIB), a salient visual target surrounded …

Resting-state functional magnetic resonance imaging (rs-fMRI) is widely used to investigate
the functional architecture of the healthy human brain and how it is affected by learning …

During binocular rivalry, perception spontaneously changes without any alteration to the
visual stimulus. What neural events bring about this illusion that a constant stimulus is …
