Article
Full-text available
The temporal lobe has been associated with various cognitive functions which include memory, auditory cognition and semantics. However, at a higher level of conceptualisation, all of the functions associated with the temporal lobe can be considered as lying along one major axis; from modality-specific to modality-general processing. This paper used...
Article
Full-text available
The temporal lobe has been implicated in multiple cognitive domains through lesion studies as well as cognitive neuroimaging research. There has been a recent increased interest in the structural and connective architecture that underlies these functions. However there has not yet been a comprehensive exploration of the patterns of connectivity tha...
Preprint
Full-text available
Investigating task- and stimulus-dependent connectivity is key to understanding how brain regions interact to perform complex cognitive processes. Most existing connectivity analysis methods reduce activity within brain regions to unidimensional measures, resulting in a loss of information. While recent studies have introduced new functional connec...
Poster
Full-text available
Currently, there is a lack of consensus on whether brain regions involved in social processing are specialised for that domain or subserve a more general underlying function 1–5. Moreover, the extent to which domain-general systems contribute to social cognition remains unclear. Recently, it has been proposed that the semantic system involved in ex...
Poster
Full-text available
The left inferior frontal gyrus (IFG) has been associated with numerous cognitive domains, including executive control, language, semantics and social cognition. One possibility, therefore, is that IFG subregions will reveal multiple functional specialisations. However, the organisation of this region and the degree to which functional differentiat...
Preprint
Full-text available
Functional and effective connectivity methods are essential to study the complex information flow in brain networks underlying human cognition. Only recently have connectivity methods begun to emerge that make use of the full multidimensional information contained in patterns of brain activation, rather than univariate summary measures of these pat...
Preprint
Full-text available
Control processes are critical for the generation of task-appropriate behaviour across cognitive domains, yet children have a long developmental period with reduced executive control. Traditionally, this is viewed as a negative but necessary consequence of the time taken to learn control processes and develop the prefrontal cortex. Here, we exploit...
Article
Full-text available
The human dorsolateral prefrontal cortex (DLPFC, approximately corresponding to Brodmann areas 9 and 46) has demonstrable roles in diverse executive functions such as working memory, cognitive flexibility, planning, inhibition, and abstract reasoning. However, it remains unclear whether this is the result of one functionally homogeneous region or w...
Preprint
Full-text available
The posterior lateral temporal cortex is implicated in many verbal, nonverbal and social cognitive domains and processes. Yet without directly comparing these disparate domains, the region's organisation remains unclear; do distinct processes engage discrete subregions, or could different domains engage shared neural correlates and processes? Here,...
Article
Full-text available
How does brain activity in distributed semantic brain networks evolve over time, and how do these regions interact to retrieve the meaning of words? We compared spatiotemporal brain dynamics between visual lexical and semantic decision tasks (LD and SD), analysing whole-cortex evoked responses and spectral functional connectivity (coherence) in sou...
Article
Full-text available
Understanding the different neural networks that support human language is an ongoing challenge for cognitive neuroscience. Which divisions are capable of distinguishing the functional significance of regions across the language network? A key separation between semantic cognition and phonological processing was highlighted in early meta-analyses,...

Article

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. By systematically varying the structure of a computational model and assessing the functional consequences, we identified the architectu...

Resting-state network research is extremely influential, yet the functions of many networks remain unknown. Hypotheses implicating the default mode network (DMN) in episodic memory and social cognition are highly popular. Univariate analyses and meta-analyses of these functions show activation in similar regions to the DMN. However, this does not n...

Semantic control, the ability to selectively access and manipulate meaningful information on the basis of context demands, is a critical component of semantic cognition. The precise neural correlates of semantic control are disputed, with particular debate surrounding parietal involvement, the spatial extent of the posterior temporal contribution a...

Article
Full-text available
The parietal cortex (PC) is implicated in a confusing myriad of different cognitive processes/tasks. Consequently, understanding the nature and organization of the core underlying neurocomputations is challenging. According to the Parietal Unified Connectivity-biased Computation model, two properties underpin PC function and organization. Firstly,...

We present a reverse engineering approach to deconstruct cognition into neurocomputational mechanisms and their underlying cortical architecture, using controlled semantic cognition as a test case. By systematically varying the structure of a computational model and assessing the functional consequences, we identified architectural properties neces...

Article
Full-text available
The functional heterogeneity of the ventromedial prefrontal cortex (vmPFC) suggests it may include distinct functional subregions. To date these have not been well elucidated. Regions with differentiable connectivity (and as a result likely dissociable functions) may be identified using emergent data-driven approaches. However, prior parcellations...
Article
Full-text available
Resting-state networks (RSNs; groups of regions consistently co-activated without an explicit task) are hugely influential in modern brain research. Despite this popularity, the link between specific RSNs and their functions remains elusive, limiting the impact on cognitive neuroscience (where the goal is to link cognition to neural systems). Here...
Article
Unlabelled: The anterior temporal lobe (ATL) makes a critical contribution to semantic cognition. However, the functional connectivity of the ATL and the functional network underlying semantic cognition has not been elucidated. In addition, subregions of the ATL have distinct functional properties and thus the potential differential connectivity b...
Article
Full-text available
The ability to represent concepts and the relationships between them is critical to human cognition. How does the brain code relationships between items that share basic conceptual properties (e.g., dog and wolf) while simultaneously representing associative links between dissimilar items that co-occur in particular contexts (e.g., dog and bone)? T...
Article
Despite indications that regions within the anterior temporal lobe (ATL) might make a crucial contribution to pan-modal semantic representation, to date there have been no investigations of when during semantic processing the ATL plays a critical role. To test the timing of the ATL involvement in semantic processing, we studied the effect of double...
Article
Full-text available
Emotional memories tend to be strengthened ahead of neutral memories during sleep-dependent consolidation. In recent work, however, we found that this is not the case when emotion pertains to the contextual features of a memory instead of its central constructs, suggesting that emotional contexts are influenced by distinct properties of sleep. We t...
