Dissociations in semantic cognition: Oscillatory evidence for opposing effects of semantic control and type of semantic relation in anterior and posterior temporal cortex.

Cortex, 2019
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 ...

Revealing the Dynamic Modulations That Underpin a Resilient Neural Network for Semantic Cognition: An fMRI Investigation in Patients With Anterior Temporal Lobe Resection. [PDF]

Cereb Cortex, 2018
One critical feature of any well-engineered system is its resilience to perturbation and minor damage. The purpose of the current study was to investigate how resilience is achieved in higher cognitive systems, which we explored through the domain of ...

Degrees of lateralisation in semantic cognition: Evidence from intrinsic connectivity

NeuroImage, 2019
The semantic network is thought to include multiple components, including heteromodal conceptual representations and semantic control processes that shape retrieval to suit the circumstances.

The neural basis of naturalistic semantic and social cognition

Scientific Reports
Decoding social environments and engaging meaningfully with other people are critical aspects of human cognition. Multiple cognitive systems, including social and semantic cognition, work alongside each other to support these processes.

Using a combination of fMRI and anterior temporal lobe rTMS to measure intrinsic and induced activation changes across the semantic cognition network

Neuropsychologia, 2015
By developing and applying a method which combines fMRI and rTMS to explore semantic cognition, we identified both intrinsic (related to automatic changes in task/stimulus-related processing) and induced (i.e., associated with the effect of TMS ...

Leveraging Prior Concept Learning Improves Generalization From Few Examples in Computational Models of Human Object Recognition

Frontiers in Computational Neuroscience, 2021
Humans quickly and accurately learn new visual concepts from sparse data, sometimes just a single example. The impressive performance of artificial neural networks which hierarchically pool afferents across scales and positions suggests that the ...

Validated measures of semantic knowledge and semantic control: normative data from young and older adults for more than 300 semantic judgements

Royal Society Open Science, 2022
Recent studies suggest that knowledge representations and control processes are the two key components underpinning semantic cognition, and are also crucial indicators of the shifting cognitive architecture of semantics in later life.

Research on Discrete Semantics in Continuous Hand Joint Movement Based on Perception and Expression

Sensors, 2021
Continuous movements of the hand contain discrete expressions of meaning, forming a variety of semantic gestures. For example, it is generally considered that the bending of the finger includes three semantic states of bending, half bending, and ...

Spatial Imagination With Semantic Cognition for Mobile Robots [PDF]

IEEE/RJS International Conference on Intelligent RObots and Systems, 2021
The imagination of the surrounding environment based on the experience and semantic cognition has great potential to extend the limited observations to leverage the ability for mapping, collision avoidance and path planning.

Flexing the principal gradient of the cerebral cortex to suit changing semantic task demands

eLife, 2022
Understanding how thought emerges from the topographical structure of the cerebral cortex is a primary goal of cognitive neuroscience. Recent work has revealed a principal gradient of intrinsic connectivity capturing the separation of sensory-motor ...
