Topographic principles of macroscale cortical connectivity

Daniel Margulies (CNRS UMR 7225, Institut du Cerveau et de la Moelle épinière (ICM))

Abstract: What determines the spatial arrangement of distinct areas of the cerebral cortex? Insights into functional processing streams indicate that areas are arranged stepwise, such that adjacent spatial position along the cortical mantle represents functional gradients. Having been largely restricted to describing processing within specific sensory modalities, how do these principles generalize across modalities and extend to the surrounding association cortex? I will present recent work describing various features of a principal gradient in cortical connectivity that spans between primary sensory/motor areas and higher-order transmodal association regions that in humans are known as the default-mode network. This arrangement suggests developmental mechanisms giving rise to the spatial distribution of cortical functions, and provides an anatomical scaffolding for investigating the propagation of information at both local and distributed spatial scales.

Searching for the elements of thought - exploring the role of the default mode network in human cognition

Jonathan Smallwood (University of York)

Abstract: Since it’s discovery at the turn of the century, the functions of the default mode network have become a major focus of research in human cognitive neuroscience. Although initially viewed as a task-negative system, recent work has suggested that this network may instead play an important functional role in cognition. In particular, it is possible that this large scale system reflects the process through which complementary yet distinct representations are brought together, a process that allows cognition to be guided by representations other than information in the immediate environment. The current talk will discuss recent evidence from our lab that are generally consistent with this integrative view of default mode network function.
