The contributions of posterior lateral temporal cortex to language and control networks
type: CreativeWork
description: Within cognitive neuroscience, understanding how the brain supports the flexible use of language and meaning remains an ongoing challenge. In recent years, the Controlled Semantic Cognition framework has offered an account of the neural correlates of representation and control of meaningful information. The context-independent storage of semantic representations is subserved by the bilateral anterior temporal lobe hub and its connections to modality-specific spokes distributed throughout the cortex, while semantic control – the flexible, goal-oriented access and manipulation of this meaningful information – relies upon a left-lateralised set of frontal and temporal brain regions. However, we do not yet understand precisely how these two networks may integrate. Further, the set of regions supporting semantics overlaps somewhat with phonological processing, and the semantic control network is distinct, but overlapping with, the multiple demand network for domain-general executive control. This raises the question of how semantic representation and control might relate to other domains. The exact extent of this overlap, and the implications this has both for role of individual regions, is still uncertain. One such region is the posterior lateral temporal cortex (pLTC). Many disparate literatures have made claims about the function of the pLTC or subregions within, suggesting involvement in domains such as phonology, semantics, social processing, and both semantic and domain-general control. However, it remains unclear how this area is organised, including which subregions might be recruited by the different language, semantic and control networks in which the pLTC has been implicated, the domain-specificity of the control processes supported by these subregions, and whether the pLTC is a site of integration between networks. To address these questions, Chapters 2 and 3 employ activation likelihood estimation meta-analysis at the whole brain and region of interest (ROI)…
