Color assimilation without awareness of color context Open
Contextual effects are ubiquitous in color perception. For example, in color assimilation, the color of an object shifts towards the color of the inducing context. However, it is unknown whether this effect requires awareness of the induci…

Emergence of illusory shapes from invisible inducers Open
Several studies have claimed that unconscious vision is fast, automatic, and involves simpler forms of information processing compared to conscious perception. However, to render stimuli unconscious, experimenters often use brief stimulus …

Unconscious priming requires primary visual cortex at specific temporal phases of processing Open
Priming occurs when one stimulus (i.e., the prime) influences the processing of a subsequently presented stimulus (i.e., the target), even when the first stimulus remains unconscious. Although examples of unconscious shape priming have bee…

Saliency affects feedforward more than feedback processing in primary visual cortex Open
Visual cortex activity is influenced by both top-down attention and bottom-up saliency effects. We used transcranial magnetic stimulation (TMS) over primary visual cortex to investigate how different feature tasks and saliencies influence …

Activation of complex stimulus-response mappings without visual awareness Open
Conscious representations are generally thought to entail deeper or more complex forms of information processing. Although several priming studies support this claim, other studies show unconscious semantic processing or even unconscious c…

MecA dampens transitions to spore, biofilm exopolysaccharide and competence expression by two different mechanisms Open
Summary The adapter protein MecA targets the transcription factor ComK for degradation by the ClpC/ClpP proteolytic complex, thereby negatively regulating competence in Bacillus subtilis . Here we show that MecA also decreases the frequenc…

Illusory brightness priming occurs without awareness Open
Our visual systems are usually confronted with large quantities of information, but due to processing constraints, only a small subset of this information enters awareness. Thus, one issue of fundamental importance in vision is whether con…

A MecA Paralog, YpbH, Binds ClpC, Affecting both Competence and Sporulation Open
ComK, the master regulator of competence, is degraded by the general stress-related protease ClpCP but must be targeted to this protease by binding to the adapter protein MecA. The genome of Bacillus subtilis contains a paralog of mecA , y…

Microarray analysis of the <i>Bacillus subtilis</i> K‐state: genome‐wide expression changes dependent on ComK Open
Summary In Bacillus subtilis , the competence transcription factor ComK activates its own transcription as well as the transcription of genes that encode DNA transport proteins. ComK is expressed in about 10% of the cells in a culture grow…
