DOI: 10.1002/hbm.25889
Abstract: Rapidly detecting salient information in our environments is critical for survival. Visual processing in subcortical areas like the pulvinar and amygdala has been shown to facilitate unconscious processing of salient stimuli. It is unknown, however,… read more here.

Acceleration of information processing en route to perceptual awareness in infancy
Sign Up to like & getrecommendations! Published in 2022 at "Current Biology"
DOI: 10.1016/j.cub.2022.01.029
Abstract: Electrophysiological studies1-6 have suggested an acceleration in information processing in the first years of life, probably largely caused by the progressive myelination of the cortex.7,8 Here, we ask whether and how this acceleration affects information… read more here.

Cognitive development: Looking for perceptual awareness in human infants
Sign Up to like & getrecommendations! Published in 2022 at "Current Biology"
DOI: 10.1016/j.cub.2022.02.045
Abstract: The extent to which young human infants are conscious, in the sense of being perceptually aware of their environment, has been long debated. A new study has revealed that infants do exhibit a key signature… read more here.

Perceptual awareness negativity: a physiological correlate of sensory consciousness
Sign Up to like & getrecommendations! Published in 2021 at "Trends in Cognitive Sciences"
DOI: 10.1016/j.tics.2021.05.009
Abstract: Much research on the neural correlates of consciousness (NCC) has focused on two evoked potentials, the P3b and the visual or auditory awareness negativity (VAN, AAN). Surveying a broad range of recent experimental evidence, we… read more here.

Prior Expectation Modulates Repetition Suppression without Perceptual Awareness

DOI: 10.1038/s41598-018-23467-3
Abstract: Stimulus repetition induces attenuated brain responses. This phenomenon, termed repetition suppression (RS), is classically held to stem from bottom-up neuronal adaptation. However, recent studies suggest that RS is driven by top-down predictive mechanisms. It remains… read more here.

DOI: 10.1038/s41598-019-53637-w
Abstract: Which brain regions contribute to the perceptual awareness of touch remains largely unclear. We collected structural magnetic resonance imaging scans and neurological examination reports of 70 patients with brain injuries or stroke in S1 extending… read more here.

DOI: 10.1038/s41598-021-90183-w
Abstract: Information integration is considered a hallmark of human consciousness. Recent research has challenged this tenet by showing multisensory interactions in the absence of awareness. This psychophysics study assessed the impact of spatial and semantic correspondences… read more here.

The Mismeasure of Consciousness: A Problem of Coordination for the Perceptual Awareness Scale

DOI: 10.1086/705509
Abstract: As for most measurement procedures in the course of their development, measures of consciousness face the problem of coordination, that is, the problem of knowing whether a measurement procedure actually measures what it is intended… read more here.

Perceptual awareness and active inference
Sign Up to like & getrecommendations! Published in 2019 at "Neuroscience of Consciousness"
DOI: 10.1093/nc/niz012
Abstract: Abstract Perceptual awareness depends upon the way in which we engage with our sensorium. This notion is central to active inference, a theoretical framework that treats perception and action as inferential processes. This variational perspective… read more here.

Investigating the influence of masker and target properties on the dynamics of perceptual awareness under informational masking
Sign Up to like & getrecommendations! Published in 2023 at "PLOS ONE"
DOI: 10.1371/journal.pone.0282885
Abstract: Informational masking has been investigated using the detection of an auditory target embedded in a random multi-tone masker. The build-up of the target percept is influenced by the masker and target properties. Most studies dealing… read more here.
