Investigation of the multiple-demand network at multiple spatial scales
… dissertation investigates the frontoparietal ‘multiple-demand’ (MD) network that is involved in the processing of diverse cognitive demands. This network is active when the task at hand is made more demanding, in a variety of different tasks including working memory, task switching, inhibition, …

The role of the default mode network in contextual control
… cognitive control and the default mode network. Chapter 2 considers why current studies of contextual control do not implicate DMN regions by comparing context-dependent decision making using rich, meaningful scenes, in comparison to arbitrary letter stimuli. DMN regions of the posterior …

The role of language in broader human cognition: evidence from neuroscience
… I investigate activity in the brain’s language network in response to computer code, an input that shares many structural similarities with natural language. I find that, despite these similarities, the language network responds weakly or not at all during computer code comprehension; instead, …

The Functional architecture of language comprehension mechanisms : fundamental principles revealed with fMRI
… this approach, I first contrast two cortical networks engaged in comprehension: one, the "high-level language network", is selectively recruited by linguistic processing but not by other cognitive functions; another, the "multiple-demand network", is recruited across diverse cognitive tasks, …

Representational dynamics across multiple timescales in human cortical networks
Human cognition occurs at multiple timescales, including immediate processing of the ongoing experiences and slowly drifting higher-level thoughts. To understand how the brain selects and represents these various types of information to guide behavior, this thesis examined representational content …

Electrophysiological systems underlying human domain-general cognition and selective attention
… these electrophysiological responses encode task demands across diverse cognitive domains and guide attentional control. In Chapter 2, I use MEG/EEG to investigate the contributions of aperiodic and oscillatory systems to human domain-general cognition. By applying irregular-resampling …

The contributions of posterior lateral temporal cortex to language and control networks
… we do not yet understand precisely how these two networks may integrate. Further, the set of regions supporting semantics overlaps somewhat with phonological processing, and the semantic control network is distinct, but overlapping with, the multiple demand network for domain-general executive …
