Heteromodal conceptual processing in the angular gyrus

Michael F. Bonner, Jonathan E. Peelle, Philip A. Cook, Murray Grossman
2013 NeuroImage  
We found that the angular gyrus was activated across all categories regardless of their modality-specific feature associations, consistent with a heteromodal account for the angular gyrus.  ...  These findings are consistent with a distributed semantic network that includes a heteromodal, integrative component in the angular gyrus in combination with sensory-motor feature representations in modality-specific  ...  Nonetheless, further work is needed to address the precise relationship between lexical and conceptual processing in the angular gyrus.  ...

Converging Evidence for the Neuroanatomic Basis of Combinatorial Semantics in the Angular Gyrus

A. R. Price, M. F. Bonner, J. E. Peelle, M. Grossman
2015 Journal of Neuroscience  
We predicted that the highly integrative region of heteromodal association cortex in the angular gyrus would be critical for conceptual combination, given its anatomic connectivity and its strong association  ...  These converging anatomic findings are consistent with a critical role for the angular gyrus in conceptual combination.  ...  Here we test the prediction that conceptual combination relies in part on the heteromodal association cortex of the angular gyrus.  ...

The neurocognitive basis of knowledge about object identity and events: dissociations reflect opposing effects of semantic coherence and control

Elizabeth Jefferies, Hannah Thompson, Piers Cornelissen, Jonathan Smallwood
2019 Philosophical Transactions of the Royal Society of London. Biological Sciences  
The dual hub theory suggests that separate semantic stores represent knowledge of (i) taxonomic categories (in the anterior temporal lobes, ATL) and (ii) thematic associations (in angular gyrus, AG or  ...  Alternatively, the controlled semantic cognition (CSC) framework suggests that semantic processing emerges from the flexible interaction of heteromodal semantic representations in ATL with a semantic control  ...  ATL = anterior temporal lobes. pMTG = posterior middle temporal gyrus. AG = angular gyrus. IFG = inferior frontal gyrus.  ...
