Distributed and Antagonistic Contributions of Ongoing Activity Fluctuations to Auditory Stimulus Detection
TLDR
The way in which ongoing activity fluctuations impact on perception depends on the specific sensory and cognitive context that is relevant, which contradict a simple dichotomic view on the function of these two latter brain systems. Expand
Spontaneous local variations in ongoing neural activity bias perceptual decisions
TLDR
Prestimulus activity in the fusiform face area, a cortical region preferentially responding to faces, was higher when subjects subsequently perceived faces instead of the vase, which suggests that endogenous variations in prestimulus neuronal activity biased subsequent perceptual inference. Expand
The Relation of Ongoing Brain Activity, Evoked Neural Responses, and Cognition
TLDR
The relationship between the variability of ongoing and evoked brain activity is focused on, and recent reports that tie ongoing brain activity fluctuations to variability in human perception and behavior are reviewed. Expand
Differential BOLD Activity Associated with Subjective and Objective Reports during “Blindsight” in Normal Observers
TLDR
The results show a robust dissociation between brain regions and type of report, and support the notion that subjective and objective reports tap cortical signals of different location and amplitude within the visual cortex. Expand
Probing the cortical network underlying the psychological refractory period: A combined EEG–fMRI study
TLDR
The results show that combining neuroimaging methods of high spatial and temporal resolutions can help to identify cortical regions underlying the central bottleneck of information processing, and strengthen the conclusion that fronto-parietal cortical regions participate in a distributed "global neuronal workspace" system that underlies the generation of the P3 component. Expand
Ongoing Activity Fluctuations in hMT+ Bias the Perception of Coherent Visual Motion
TLDR
The data suggest that endogenous fluctuations in baseline activity have a generic effect on subsequent perceptual decisions, in accord with postulates from theoretical frameworks as, for instance, predictive coding. Expand
Predictive Coding or Evidence Accumulation? False Inference and Neuronal Fluctuations
TLDR
Findings from two independent perceptual experiments conducted during functional magnetic resonance imaging with a sparse event-related design suggest that cortical activity in sensory brain areas reflects the precision of prediction errors and not just the sensory evidence or prediction errors per se. Expand
Temporal Tuning Properties along the Human Ventral Visual Stream
TLDR
Functional magnetic resonance imaging is used to measure regional variations of temporal sensitivity along the human ventral visual stream to quantify neural response properties that are likely to be operational during natural vision and that provide putative neurofunctional substrates of mechanisms relevant in several psychophysical phenomena as masking and the attentional blink. Expand
The link between fMRI-BOLD activation and perceptual awareness is "stream-invariant" in the human visual system.
TLDR
The results show that despite their substantial difference in connectivity and neuroanatomical specialization, both ventral and dorsal stream areas revealed a similarly tight link to perceptual awareness, that is, strong functional magnetic resonance imaging-blood oxygenation level-dependent activity for visible tools but a significant reduction of activity in the invisible condition. Expand
Give it time: Neural evidence for distorted time perception and enhanced memory encoding in emotional situations
TLDR
It is suggested that processing is accelerated during the experience of emotionally aversive events, presumably in the service of memory-related operations, resulting in better encoding but at the expense of time perception accuracy. Expand
