The visual word form area: spatial and temporal characterization of an initial stage of reading in normal subjects and posterior split-brain patients.
The findings provide direct support for the main components of the classical model of reading and help specify their timing and cerebral substrates.
Cerebral mechanisms of word masking and unconscious repetition priming
Within the areas associated with conscious reading, masked words activated left extrastriate, fusiform and precentral areas and reduced the amount of activation evoked by a subsequent conscious presentation of the same word.
Imaging unconscious semantic priming
The results indicate that masked stimuli have a measurable influence on electrical and haemodynamic measures of brain activity and a stream of perceptual, semantic and motor processes can occur without awareness.
Neural signature of the conscious processing of auditory regularities
An auditory paradigm that evaluates cerebral responses to violations of temporal regularities that are either local in time or global across several seconds suggests that the presence of the global effect is a signature of conscious processing, although it can be absent in conscious subjects who are not aware of theglobal auditory regularities.
Letter Binding and Invariant Recognition of Masked Words
The results indicate that an invariant binding of letters into words is achieved unconsciously through a series of increasingly invariant stages in the left occipito-temporal pathway.
Evidence for a hierarchy of predictions and prediction errors in human cortex
Simultaneous EEE- magnetoencephalographic recordings verify the predictions of hierarchical predictive coding hypothesis and suggest that higher-order predictions appear to be generated in multiple areas of frontal and associative cortices.
The priming method: imaging unconscious repetition priming reveals an abstract representation of number in the parietal lobes.
This work exposes the general logic, potential and limitations of the priming method and illustrates it by demonstrating that a region of parietal cortex is coding for numbers at the quantity level, independently of other stimulus attributes, and that this region processes both consciously and unconsciously perceived stimuli.
