The visual word form area: spatial and temporal characterization of an initial stage of reading in normal subjects and posterior split-brain patients.

Laurent Cohen, Stanislas Dehaene, +4 authors François Michèl
Brain : a journal of neurology
2000

A standard model of word reading postulates that visual information is initially processed by occipitotemporal areas contralateral to the stimulated hemifield, from whence it is subsequently… (More)

Towards a cognitive neuroscience of consciousness: basic evidence and a workspace framework

This introductory chapter attempts to clarify the philosophical, empirical, and theoretical bases on which a cognitive neuroscience approach to consciousness can be founded. We isolate three major… (More)

Cerebral mechanisms of word masking and unconscious repetition priming

Stanislas Dehaene, Lionel Naccache, +4 authors Denis Rivière
Nature Neuroscience
2001

We used functional magnetic resonance imaging (fMRI) and event-related potentials (ERPs) to visualize the cerebral processing of unseen masked words. Within the areas associated with conscious… (More)

Conscious, preconscious, and subliminal processing: a testable taxonomy

Stanislas Dehaene, Jean-Pierre Changeux, Lionel Naccache, Jérôme Sackur, Claire Sergent
Trends in Cognitive Sciences
2006

Of the many brain events evoked by a visual stimulus, which are specifically associated with conscious perception, and which merely reflect non-conscious processing? Several recent neuroimaging… (More)

Neural signature of the conscious processing of auditory regularities.

Tristán Bekinschtein, Stanislas Dehaene, Benjamin Rohaut, François Tadel, Laurent Cohen, Lionel Naccache
Proceedings of the National Academy of Sciences…
2009

Can conscious processing be inferred from neurophysiological measurements? Some models stipulate that the active maintenance of perceptual representations across time requires consciousness.… (More)

Unconscious semantic priming extends to novel unseen stimuli

Many subliminal priming experiments are thought to demonstrate unconscious access to semantics. However, most of them can be reinterpreted in a non-semantic framework that supposes only that subjects… (More)

Imaging unconscious semantic priming

Stanislas Dehaene, Lionel Naccache, +5 authors Denis Le Bihan
Nature
1998

Visual words that are masked and presented so briefly that they cannot be seen may nevertheless facilitate the subsequent processing of related words, a phenomenon called masked priming,. It has been… (More)

The priming method: imaging unconscious repetition priming reveals an abstract representation of number in the parietal lobes.

Lionel Naccache, Stanislas Dehaene
Cerebral cortex
2001

Most of the current brain imaging methods are limited by the low spatial resolution of neuroimaging techniques and remain unable to measure activity at the scale of single neurons or small columns of… (More)

Letter binding and invariant recognition of masked words: behavioral and neuroimaging evidence.

Stanislas Dehaene, Antoinette Jobert, +4 authors Laurent Cohen
Psychological science
2004

Fluent readers recognize visual words across changes in case and retinal location, while maintaining a high sensitivity to the arrangement of letters. To evaluate the automaticity and functional… (More)

Converging Intracranial Markers of Conscious Access

Raphaël Gaillard, Stanislas Dehaene, +5 authors Lionel Naccache
PLoS biology
2009

We compared conscious and nonconscious processing of briefly flashed words using a visual masking procedure while recording intracranial electroencephalogram (iEEG) in ten patients. Nonconscious… (More)
