Sentence comprehension in autism: thinking in pictures with decreased functional connectivity.
The findings provide further evidence of underintegration of language and imagery in autism (and hence expand the understanding of underconnectivity) but also show that people with autism are more reliant on visualization to support language comprehension.
The Timecourse of Activation Within the Cortical Network Associated with Visual Imagery
The shape of the hemodynamic timecourse appears to correspond strongly with the cognitive processing taking place within the region, not the stimulus paradigm, and has implications for the appropriateness of using the canonical hrf during fMRI data analysis.
Brain activation during sentence comprehension among good and poor readers.
It is proposed that the functioning of the cortical network underlying reading is dependent on a combination of interacting factors, including physiological maturation, neural integrity, skill level, and the nature of the task.
Task effects on BOLD signal correlates of implicit syntactic processing

BOLD signal increased in visual association areas bilaterally and left supramarginal gyrus in the contrast of sentences with object- and subject-extracted relative clauses without font changes in which the animacy order of the nouns biased against the syntactically determined meaning of the sentence.


fMRI investigation of sentence comprehension by eye and by ear: Modality fingerprints on cognitive processes
A number of subtle differences in the cognitive processing underlying listening vs. reading comprehension of sentences was compared using fMRI, and the patterns of activation particularly in cortical association areas that classically are implicated in language processing are compared.
Functional Anatomy of High-Resolution Visual Mental Imagery
There is strong evidence that imagery based on verbal descriptions can recruit regions known to be engaged in high-order visual processing and region activation in other regions was very similar in the two conditions.

Reading and listening to high and low imagery sentences
Cortical anatomy of mental imagery of concrete nouns based on their dictionary definition
It is demonstrated that a network including part of the bilateral ventral stream and the frontal working memory areas is recruited when mental imagery of concrete words is performed on the basis of continuous spoken language.
The role of left prefrontal cortex in language and memory.
This article reviews attempts to characterize the mental operations mediated by left inferior prefrontal cortex, especially the anterior and inferior portion of the gyrus, with the functional
Visual Mental Imagery Activates Topographically Organized Visual Cortex: PET Investigations
Results were consistent with the existence of two types of imagery, one that rests on allocating attention to form a pattern and one that rested on activating stored visual memories, and evidence that imagery activates topographically mapped cortex.
Neural bases of image and language interactions
Interestingly, it was also found that language areas are more likely to address a representation when language is the only source of information than when imagery and language are used in conjunction, which demonstrates a modulation of th...
Broca's region subserves imagery of motion: A combined cytoarchitectonic and fMRI study
It was found that the activation areas in the opercular portion of the inferior frontal cortex were localized to area 44 of Broca's region, suggesting that area 44 mediates higher‐order forelimb movement control resembling the neuronal mechanisms subserving speech.
Graded Functional Activation in the Visuospatial System with the Amount of Task Demand
The data suggest that the amount of activation in the various cortical regions that support visuospatial processing is related to the amount, as well as to the type, of computational demand.
