The contribution of executive control to semantic cognition: Convergent evidence from semantic aphasia and executive dysfunction. [PDF]
Semantic cognition, as described by the controlled semantic cognition (CSC) framework (Rogers et al., Neuropsychologia, 76, 220), involves two key components: activation of coherent, generalizable concepts within a heteromodal 'hub' in combination with ...

Macroscale brain states support the control of semantic cognition [PDF]
A crucial aim in neuroscience is to understand how the human brain adapts to varying cognitive demands. This study investigates network reconfiguration during controlled semantic retrieval in differing contexts. We analyze brain responses to two semantic

Healthy ageing has divergent effects on verbal and non-verbal semantic cognition. [PDF]
Semantic cognition refers to the storage and appropriate use of knowledge acquired over the lifespan and underpins our everyday verbal and non-verbal behaviours.

Age-related reorganization of functional network architecture in semantic cognition. [PDF]
Semantic memory is a fundamental human ability which is central to communication. Although it is usually well preserved in healthy aging, memory problems in verbal communication due to slowed access and retrieval processes are a common complaint with ...

The role of the angular gyrus in semantic cognition: a synthesis of five functional neuroimaging studies. [PDF]
Semantic knowledge is central to human cognition. The angular gyrus (AG) is widely considered a key brain region for semantic cognition. However, the role of the AG in semantic processing is controversial.

Age-Dependent Contribution of Domain-General Networks to Semantic Cognition. [PDF]
Aging is characterized by a decline of cognitive control. In semantic cognition, this leads to the paradox that older adults usually show poorer task performance than young adults despite their greater semantic knowledge.

Distinct but cooperating brain networks supporting semantic cognition. [PDF]
Semantic cognition is a complex brain function involving multiple processes from sensory systems, semantic systems, to domain-general cognitive systems, reflecting its multifaceted nature.

Rapid Interactions of Widespread Brain Networks Characterize Semantic Cognition. [PDF]
Language comprehension requires the rapid retrieval and integration of contextually appropriate concepts (“semantic cognition”). Current neurobiological models of semantic cognition are limited by the spatial and temporal restrictions of single-modality ...

A tale of two gradients: differences between the left and right hemispheres predict semantic cognition. [PDF]
Decomposition of whole-brain functional connectivity patterns reveals a principal gradient that captures the separation of sensorimotor cortex from heteromodal regions in the default mode network (DMN).

Reverse-engineering the cortical architecture for controlled semantic cognition. [PDF]
We employ a reverse-engineering approach to illuminate the neurocomputational building blocks that combine to support controlled semantic cognition: the storage and context-appropriate use of conceptual knowledge.
