Cookson, S. L., D’Esposito, M. (2022) HBM :: Brain network definitions typically assume nonoverlap or minimal overlap, ignoring regions’ connections to multiple networks. However, new methods are emerging that emphasize network overlap. Here, we investigated the reliability and validity of one assignment method, the mixed membership algorithm, and explored its potential utility for identifying gaps […]

Connectivity-defined subdivisions of the intraparietal sulcus respond differentially to abstraction during decision making
Newton, M., Cookson, S. L., D’Esposito, M., Kayser, A. (2022) J Neurosci :: The intraparietal sulcus (IPS) has been implicated in numerous functions that range from representation of visual stimuli to action planning, but its role in abstract decision-making has been unclear, in part because low-level functions often act as confounds. Here, we address this […]
Dissociating the neural correlates of planning and executing tasks with nested task sets
Cookson, S. L., Schumacher, E. H. (2022) JOCN :: Task processing (e.g., the preparation and execution of responses) and task representation (e.g., the activation and maintenance of stimulus–response and context information) are two facets of cognitive control supported by lateral frontal cortex (LFC). However, the mechanistic overlap (or distinction) between these two facets is unknown. […]
Centering inclusivity in the design of online conferences – An OHBM – Open Science perspective.
Levitis, E., Gould van Praag, C., Gau, R., … Cookson, S. L. … Maumet, C. (2021). Gigascience :: As the global health crisis unfolded, many academic conferences moved online in 2020. This move has been hailed as a positive step towards inclusivity in its attenuation of economic, physical, and legal barriers and effectively enabled many […]

Task sets serve as boundaries for the congruency sequence effect
Grant, L. D., Cookson, S. L., Weissman, D. H. (2020) JEPHPP :: Cognitive control processes that enable purposeful behavior are often context-specific. A teenager, for example, may inhibit the tendency to daydream at work but not in the classroom. However, the nature of contextual boundaries for cognitive control processes remains unclear. Therefore, we revisited an […]
Understanding how choice of parcellation influences network analyses
Network neuroscience uses graph theory to analyze the brain’s network properties by envisioning brain regions as nodes of the graph and their functional connectivity strength with other regions as the edges. The first step in these analyses is to define the individual regions, which will often rely on established parcellations of the brain. There are […]
