Fronto-parietal network supports context-dependent speech comprehension
2014
Neuropsychologia
Preserved Fulltext
Our results suggest that a fronto-parietal functional network supports context-dependent narrative comprehension, and that Broca's area is involved in resolving ambiguity from speech when appropriate contextual ...
Knowing the context of a discourse is an essential prerequisite for comprehension. ...

Resting-state functional connectivity of regions of interest in left IFG, pMTG and aMTG revealed highly interconnected left-lateralized fronto-temporal networks representing the semantic system. ...
Semantic control has been shown to be implemented in a network that consists of left inferior frontal (IFG), and anterior and posterior middle temporal gyri (a/ pMTG). ...
Each of these ROIs revealed a widespread and highly interconnected, mostly fronto-temporal network in accordance with prior resting-state studies [75, 35, 37] . ...
