Journal ArticleDOI
The Angular Gyrus: Multiple Functions and Multiple Subdivisions
TL;DR: The AG emerges as a cross-modal hub where converging multisensory information is combined and integrated to comprehend and give sense to events, manipulate mental representations, solve familiar problems, and reorient attention to relevant information.
Journal ArticleDOI
The Neural Architecture of the Language Comprehension Network: Converging Evidence from Lesion and Connectivity Analyses
TL;DR: The left MTG showed a particularly extensive structural and functional connectivity pattern which is consistent with the severity of the impairments associated with MTG lesions and which suggests a central role for this region in language comprehension.
Journal ArticleDOI
Thinking ahead: The role and roots of prediction in language comprehension.
TL;DR: Results suggest that, when it can, the brain uses context to predict features of likely upcoming items, and that left hemisphere language processing seems to be oriented toward prediction and the use of top-down cues, whereas right hemisphere comprehension is more bottom-up, biased toward the veridical maintenance of information.
Journal ArticleDOI
The arcuate fasciculus and the disconnection theme in language and aphasia: History and current state
Marco Catani,M.-Marsel Mesulam +1 more
TL;DR: The goal in this paper is to survey the 19th Century roots of the connectionist approach to aphasia and to describe emerging imaging technologies based on diffusion tensor imaging (DTI) that promise to consolidate and expand the disconnection approach to language and its disorders.
Journal ArticleDOI
Symmetries in human brain language pathways correlate with verbal recall
Marco Catani,Matthew Allin,Masud Husain,Luca Pugliese,M.-Marsel Mesulam,Robin M. Murray,Derek K. Jones +6 more
TL;DR: It is suggested that the degree of lateralization of perisylvian pathways is heterogeneous in the normal population and, paradoxically, bilateral representation, not extreme lateralization, might ultimately be advantageous for specific cognitive functions.

An integrative theory of prefrontal cortex function
Earl K. Miller,Jonathan D. Cohen +1 more
TL;DR: It is proposed that cognitive control stems from the active maintenance of patterns of activity in the prefrontal cortex that represent goals and the means to achieve them, which provide bias signals to other brain structures whose net effect is to guide the flow of activity along neural pathways that establish the proper mappings between inputs, internal states, and outputs needed to perform a given task.
Journal ArticleDOI
Role of left inferior prefrontal cortex in retrieval of semantic knowledge: A reevaluation
TL;DR: The findings suggest that it is selection, not retrieval, of semantic knowledge that drives activity in the left IFG, and counters the argument that the effects of selection can be attributed solely to variations in degree of semantic retrieval.
Journal ArticleDOI
Functional MRI of Language: New Approaches to Understanding the Cortical Organization of Semantic Processing
TL;DR: Three lines of fMRI research into how the semantic system is organized in the adult brain are discussed, which broaden the understanding of how the brain stores, retrieves, and makes sense of semantic information and challenge some commonly held notions of functional modularity in the language system.

Semantic Cognition: A Parallel Distributed Processing Approach
TL;DR: The authors propose that performance in semantic tasks arises through the propagation of graded signals in a system of interconnected processing units, and show how a simple computational model proposed by Rumelhart exhibits a progressive differentiation of conceptual knowledge, paralleling aspects of cognitive development seen in the work of Frank Keil and Jean Mandler.

Recovering Meaning: Left Prefrontal Cortex Guides Controlled Semantic Retrieval
TL;DR: The present event-related fMRI study provides evidence for an alternative hypothesis: LIPC guides controlled semantic retrieval irrespective of whether retrieval requires selection against competing representations.
