The posterior cingulate cortex (pCC) often deactivates during complex tasks, and at rest is only weakly correlated with regions that play a general role in the control of cognition. These observations led to hypothesis pCC contributes automatic aspects memory retrieval Recent work, however, has suggested may support both controlled forms processing do so by changing its communication are important cognition across multiple domains. current study examined these alternative views...
Activation in sensorimotor areas of the brain following perception linguistic stimuli referring to objects and actions has been interpreted as evidence for strong theories embodied semantics. Although a large number studies have demonstrated this "language-to-action" link, important questions about how activation system affects language performance ("action-to-language" link) are yet unanswered. As several authors recently pointed out, debate should move away from an "embodied or not" focus,...
The "hub and spoke model" of semantic representation suggests that the multimodal features objects are drawn together by an anterior temporal lobe (ATL) "hub", while modality-specific "spokes" capture perceptual/action features. However, relatively little is known about how these components recruited through time to support object identification. We used magnetoencephalography measure neural oscillations within left ATL, lateral fusiform cortex (FC) central sulcus (CS) during word-picture...
How does the brain represent and process different types of knowledge? The Dual Hub account postulates that anterior temporal lobes (ATL) support taxonomic relationships based on shared physical features (mole – cat), while temporoparietal regions, including posterior middle gyrus (pMTG), thematic associations earth). Conversely, Controlled Semantic Cognition proposes ATL supports both aspects knowledge, left pMTG contributes to controlled retrieval. This study used magnetoencephalography...
Distinct neural processes are thought to support the retrieval of semantic information that is (i) coherent with strongly-encoded aspects knowledge, and (ii) non-dominant yet relevant for current task or context. While brain regions readily more controlled patterns relatively well-characterised, temporal dynamics these not well-understood. This study used magnetoencephalography (MEG) dual-pulse chronometric transcranial magnetic stimulation (cTMS) in two separate experiments examine during...
An MEG study investigated the role of context in semantic interpretation by examining comprehension ambiguous words contexts leading to different interpretations. We compared high-ambiguity minimally (to bowl, bowl) low-ambiguity counterparts (the tray, flog). Whole brain beamforming revealed engagement left inferior frontal gyrus (LIFG) and posterior middle temporal (LPMTG). Points interest analyses showed that both these sites a stronger response verb-contexts 200 ms post-stimulus...
Efficient semantic cognition depends on accessing and selecting conceptual knowledge relevant to the current task or context. This study explored neurocognitive architecture that supports this function by examining how individual variation in functional brain organisation predicts comprehension generation. Participants underwent resting state magnetic resonance imaging (fMRI) and, separate days, performed written synonym judgement, letter category fluency tasks. We found better judgement for...
Rhythmic activity in populations of neurons is associated with cognitive and motor function. Our understanding the neuronal mechanisms underlying these core brain functions has benefitted from demonstrations cellular, synaptic, network phenomena, leading to generation discrete rhythms at local level. However, frequencies rhythmic rarely occur alone. Despite this, little known about why multiple are generated together or what underlie their interaction promote One overarching theory that...
