Exploring the role of the posterior middle temporal gyrus in semantic cognition: Integration of anterior temporal lobe with executive processes

Description: This study focussed on understanding the functional contribution of pMTG to semantic control and event/relational semantics: we explored the hypothesis that this region acts to integrate information from the MDN and also the DMN, which are anti-correlated at rest. First, we identified whether there are regions of pMTG that show a common response to the retrieval of action features (contrasted with colour feature judgements which have not been historically linked to pMTG; Badre et al., 2005) and global associations (relative to feature judgements). Both of these event/relational contrasts depend on retrieving information in line with a specific stimulus-driven context, as opposed to the application of a specific goal specified in the instructions. We compared the location of this response to regions implicated in semantic control and domain-general control in previous meta-analyses.
