2017 PLoS ONE  
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] .  ...

Francesca Martina Branzi, Gina Humphreys, Paul Hoffman, Matthew Lambon Ralph
2019 bioRxiv   pre-print
Secondly, semantic combinations are supported by a fronto-parietal network, possibly reflecting working memory for the integration of contextual information.  ...  Third, during the reset of the semantic gestalt, the ATL neurocomputations are accompanied by the recruitment of the multi-demand network, with a key role of brain structures in the right hemisphere, and  ...  Instead, the right pMTG shows connectivity with regions that, except for the left pMTG, constitute a right lateralised fronto-parietal network.  ...

Revealing the neural networks that extract conceptual gestalts from continuously evolving or changing semantic contexts

Francesca M. BRANZI, Gina F. HUMPHREYS, Paul HOFFMAN, Matthew A. LAMBON RALPH
2020 NeuroImage  
A distinct fronto-parietal network, instead, was recruited for context integration, independently from the meaning associations between words (semantic coherence).  ...  Univariate and multivariate techniques allowed us to draw a distinction between networks that are crucial for the formation of a semantic gestalt (meaning integration) and those that instead are important  ...  Instead, the right pMTG shows connectivity with regions that, except for the left pMTG, constitute a right lateralised fronto-parietal network.  ...

The balance between memory and unification in semantics: A dynamic account of the N400

Giosuè Baggio, Peter Hagoort
2011 Language and Cognitive Processes  
Therefore, our theory of fronto-temporal interactions in semantics could serve as a basis for a neurocomputational model of the N400.  ...  For instance, in the study by Rodd et al. (2005) , increased activation in IFG is most likely due to increased selection demands in response to sentences containing ambiguous words.  ...

Matthew H. Davis, Michael A. Ford, Ferath Kherif, Ingrid S. Johnsrude
2011 Journal of Cognitive Neuroscience  
■ When speech is degraded, word report is higher for semantically coherent sentences (e.g., her new skirt was made of denim) than for anomalous sentences (e.g., her good slope was done in carrot).  ...  Although we cannot rule out top-down effects, this pattern is more compatible with a purely feedforward or bottom-up account, in which the results of lower-level perceptual processing are passed to inferior  ...  Acknowledgments We would like to thank Jenni Rodd for help with stimulus preparation, Christian Schwarzbauer for programming the ISSS sequence, radiographers and staff at the Wolfson Brain Imaging Centre  ...

Large Scale Brain Functional Networks Support Sentence Comprehension: Evidence from Both Explicit and Implicit Language Tasks

Zude Zhu, Yuanyuan Fan, Gangyi Feng, Ruiwang Huang, Suiping Wang, Hengyi Rao
2013 PLoS ONE  
This discrepancy has raised questions regarding a common network for sentence comprehension that acts regardless of task effect and whether different tasks modulate network properties.  ...  Previous studies have indicated that sentences are comprehended via widespread brain regions in the fronto-temporoparietal network in explicit language tasks (e.g., semantic congruency judgment tasks),  ...  Thus, we obtained a 90690 symmetrical connectivity matrix for each task in each subject.  ...
