The neural basis of semantic cognition: Converging evidence from neuropsychology, neuroimaging and TMS
TLDR
The next challenges are to delineate the specific roles of each region within the semantic control network and to specify the way in which control processes interact with semantic representations to focus processing on relevant features of concepts.About:

TL;DR: An overarching organization of large-scale connectivity that situates the default-mode network at the opposite end of a spectrum from primary sensory and motor regions is described, suggesting that the role of the DMN in cognition might arise from its position at one extreme of a hierarchy, allowing it to process transmodal information that is unrelated to immediate sensory input.
Journal ArticleDOI
The neural and computational bases of semantic cognition
TL;DR: This Review summarizes key findings and issues arising from a decade of research into the neurocognitive and neurocomputational underpinnings of semantic cognition, leading to a new framework that is term controlled semantic cognition (CSC).

Semantic dementia: progressive fluent aphasia with temporal lobe atrophy
TL;DR: The term semantic dementia is proposed, first coined by Snowden et al. (1989), to designate this clinical syndrome characterized by fluent dysphasia with severe anomia, reduced vocabulary and prominent impairment of single-word comprehension, progressing to a stage of virtually complete dissolution of the semantic components of language.

Going beyond Inferior Prefrontal Involvement in Semantic Control: Evidence for the Additional Contribution of Dorsal Angular Gyrus and Posterior Middle Temporal Cortex
TL;DR: A formal meta-analysis of studies that contrasted semantic tasks with high > low executive requirements to determine whether cortical regions beyond the left pFC show the same response profile to executive semantic demands revealed substantial overlap between the two sets of contrasts within left ventral pFC.

The Neural Representation of Abstract Words: The Role of Emotion
Gabriella Vigliocco,Stavroula Kousta,Pasquale Anthony Della Rosa,David Vinson,Marco Tettamanti,Joseph T. Devlin,Stefano F. Cappa +6 more
TL;DR: A functional magnetic resonance imaging experiment is reported that shows greater engagement of the rostral anterior cingulate cortex, an area associated with emotion processing, supporting the view that engagement of emotional processing is generally required for processing abstract words.

Perceptual symbol systems.
TL;DR: A perceptual theory of knowledge can implement a fully functional conceptual system while avoiding problems associated with amodal symbol systems and implications for cognition, neuroscience, evolution, development, and artificial intelligence are explored.

Where Is the Semantic System? A Critical Review and Meta-Analysis of 120 Functional Neuroimaging Studies
TL;DR: In this article, the authors analyzed 120 functional neuroimaging studies focusing on semantic processing and identified reliable areas of activation in these studies using the activation likelihood estimate (ALE) technique, which formed a distinct, left-lateralized network comprised of 7 regions: posterior inferior parietal lobe, middle temporal gyrus, fusiform and parahippocampal gyri, dorsomedial prefrontal cortex, inferior frontal gyrus and posterior cingulate gyrus.

Using confidence intervals in within-subject designs
TL;DR: It is argued that to best comprehend many data sets, plotting judiciously selected sample statistics with associated confidence intervals can usefully supplement, or even replace, standard hypothesis-testing procedures.

Where do you know what you know? The representation of semantic knowledge in the human brain.
TL;DR: A patient with semantic dementia — a neurodegenerative disease that is characterized by the gradual deterioration of semantic memory — was being driven through the countryside to visit a friend and was able to remind his wife where to turn along the not-recently-travelled route.
