Parsing a cognitive task: A characterization of the mind’s bottleneck
- …Parsing a mental operation into components, characterizing the parallel or serial nature of this flow, and understanding what each process ultimately contributes to response time are fundamental questions in cognitive neuroscience. Here we show how a simple theoretical model leads to an extended set…

Neural Mechanisms for Access to Consciousness
- …Introduction: the challenge of a science of consciousness Understanding consciousness has become the ultimate intellectual challenge of this new millennium. Even if philosophers now accept the notion that it is a "real , natural, biological phenomenon literally located in the brain" (Revonsuo, 2001…

Specialization within the ventral stream: the case for the visual word form area
- …nce is often relative rather than absolute. We conclude that learning to read results in the progressive development of an inferotemporal region increasingly responsive to visual words, which is aptly named the visual word form area (VWFA).

Is consciousness a gradual phenomenon? Evidence for an all-or-none bifurcation during the attentional blink
- …Several theories of the neural correlates of consciousness assume that there is a continuum of perception, associated with a gradual change in the intensity of brain activation. But some models, considering reverberation of neural activity as necessary for conscious perception, predict a sharp non-l…

Neologistic jargon sparing numbers: a category specific phonological impairment
- …We report the case of a patient suffering from a severe neologistic jargon sparing number words. Neologisms resulted from pervasive phoneme substitutions with frequent preservation of the overall syllabic structure (e.g. /revolver / ® /reveltil/). Word and nonword reading, as well as picture naming,…

Functional neuroimaging of speech perception in infants
- …Human infants begin to acquire their native language in the first months of life. To determine which brain regions support language processing at this young age, we measured with functional magnetic resonance imaging the brain activity evoked by normal and reversed speech in awake and sleeping 3-mon…

Research Focus
- …he `scaling problem' was integral to the birth of psychology as a scientific discipline. Founding fathers of experimental psychology, inlcuding Weber and Fechner considered as one of their central goals the mathematical description of how a continuum of sensation, such as loudness or duration, is re…

Conscious, preconscious, and subliminal processing: A testable taxonomy
- …Of the many brain events evoked by a visual stimulus, which are specifically associated with conscious perception, andwhichmerelyreflectnon-conscious processing? Several recent neuroimaging studies have contrasted conscious and non-conscious visual processing, but their results appear inconsistent. …

A cognitive characterization of dyscalculia in Turner syndrome
- …Current theories of number processing postulate that the human abilities for arithmetic are based on cerebral circuits that are partially laid down under genetic control and later modified by schooling and education. This view predicts the existence of genetic diseases that interfere specifically wi…
