Journal ArticleDOI
The neural code for written words: a proposal
TL;DR: A tentative neuronal model is proposed according to which part of the occipito-temporal 'what' pathway is tuned to writing and forms a hierarchy of local combination detectors sensitive to increasingly larger fragments of words.
Journal ArticleDOI
Brain states: top-down influences in sensory processing.
TL;DR: New findings on the diversity of top-down interactions show that cortical areas function as adaptive processors, being subject to attention, expectation, and perceptual task.
Journal ArticleDOI
The neural basis of perceptual learning.
TL;DR: The neural substrate of perceptual learning relates to the nature of the neural code itself, including changes in cortical maps, in the temporal characteristics of neuronal responses, and in modulation of contextual influences.
Journal ArticleDOI
Hierarchical Coding of Letter Strings in the Ventral Stream: Dissecting the Inner Organization of the Visual Word-Form System
Fabien Vinckier,Fabien Vinckier,Stanislas Dehaene,Antoinette Jobert,Jean Philippe Dubus,Mariano Sigman,Mariano Sigman,Laurent D. Cohen +7 more
TL;DR: It is concluded that the left occipitotemporal visual word-form area presents a high degree of functional and spatial hierarchical organization which must result from a tuning process during reading acquisition.
Journal ArticleDOI
Signature of consciousness in the dynamics of resting-state brain activity.
Pablo Barttfeld,Pablo Barttfeld,Lynn Uhrig,Jacobo D. Sitt,Mariano Sigman,Béchir Jarraya,Stanislas Dehaene +6 more
TL;DR: These results reconcile theories of consciousness with observations of long-range correlation in the anesthetized brain and show that a rich functional dynamics might constitute a signature of consciousness, with potential clinical implications for the detection of awareness in anesthesia and brain-lesioned patients.
