Despite a recent upsurge of research, much remains unknown about the neurobiological
mechanisms underlying synaesthesia. By integrating results obtained so far in Magnetic …

Diffusion tensor imaging allowed us to validate for the first time the hypothesis that hyperconnectivity
causes the added sensations in synesthesia. Grapheme-color synesthetes (n = 18), …

Background Classic work on visual short-term memory (VSTM) suggests that people store a
limited amount of items for subsequent report. However, when human observers are cued to …

In masking, a stimulus is rendered invisible through the presentation of a second stimulus
shortly after the first. Over the years, authors have typically explained masking by postulating …

To further our understanding of the function of conscious experience we need to know
which cognitive processes require awareness and which do not. Here, we show that an …

Fronto-basal ganglia pathways play a crucial role in voluntary action control, including the
ability to inhibit motor responses. Response inhibition might be mediated via a fast hyperdirect …

Cognitive control processes involving prefrontal cortex allow humans to overrule and inhibit
habitual responses to optimize performance in new and challenging situations, and …

The ability to suppress one's impulses and actions constitutes a fundamental mechanism of
cognitive control, thought to be subserved by the right inferior frontal cortex (rIFC). The …

Abstract Abstract: Abstract What is the relationship between top-down and bottom-up
attention? Are both types of attention tightly interconnected, or are they independent? We …

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