Periodic, well timed exposure to light is important for our health and wellbeing. Light, in
particular in the blue part of the spectrum, is thought to affect alertness both indirectly, by …

Recent studies using continuous flash suppression suggest that invisible stimuli are processed
as integrated, semantic entities. We challenge the viability of this account, given recent …

Virtual reality (VR) offers many opportunities for post-stroke rehabilitation. However,“VR” can
refer to several types of computer-based rehabilitation systems. Since these systems may …

The slant of a stereoscopically defined surface cannot be determined solely from horizontal
disparities or from derived quantities such as horizontal size ratio (HSR). There are four other …

When our two eyes view incongruent images, we experience binocular rivalry: An ongoing
cycle of dominance periods of either image and transition periods when both are visible. Two …

Immersive virtual reality has become increasingly popular to improve the assessment and
treatment of health problems. This rising popularity is likely to be facilitated by the availability …

When sensory input allows for multiple, competing perceptual interpretations, observers'
perception can fluctuate over time, which is called bistable perception. Imaging studies in …

Voluntary control and conscious perception seem to be related: when we are confronted
with ambiguous images we are in some cases and to some extent able to voluntarily select a …

The neural mechanisms underlying attentional selection of competing neural signals for
awareness remains an unresolved issue. We studied attentional selection, using perceptually …

Studying the temporal dynamics of bistable perception can be useful for understanding
neural mechanisms underlying the phenomenon. We take a closer look at those temporal …
