Connectivity of submodular functions
This paper relates the connectivity of submodular functions \(f\) to that of certain submodular functions which are derived from \(f\). Here the function \(f\) on \(S\) is submodular if \(f(A)+f(B)\geq f(A\cup B)+f(A\cap B)\) for all subsets \(A\) and \(B\) of \(S\).

Biophysical Modulations of Functional Connectivity [PDF]
Resting-state low frequency oscillations have been detected in many functional magnetic resonance imaging (MRI) studies and appear to be synchronized between functionally related areas. Converging evidence from MRI and other imaging modalities suggest that this activity has an intrinsic neuronal origin.

Differentiating the functional contributions of resting connectivity networks to memory decision-making : fMRI support for multi-stage control processes [PDF]
Neural substrates of memory control are engaged when participants encounter unexpected mnemonic stimuli (e.g., a new word when told to expect an old word).

Insula Functional Connectivity in Schizophrenia [PDF]
Abstract The insula is structurally abnormal in schizophrenia, demonstrating robust reductions in gray matter volume, cortical thickness, and altered gyrification during prodromal, early and chronic stages of the illness. Despite compelling structural alterations, less is known about its functional connectivity, limited by studies ...

The Functional Relevance of Task-State Functional Connectivity [PDF]
Resting-state functional connectivity has provided substantial insight into intrinsic brain network organization, yet the functional importance of task-related change from that intrinsic network organization remains unclear. Indeed, such task-related changes are known to be small, suggesting they may have only minimal functional relevance ...

Neural activation and functional connectivity during motor imagery of bimanual everyday actions [PDF]
Bimanual actions impose intermanual coordination demands not present during unimanual actions. We investigated the functional neuroanatomical correlates of these coordination demands in motor imagery (MI) of everyday actions using functional magnetic ...

Changes in functional connectivity within the rat striatopallidal axis during global brain activation in vivo [PDF]
The functional organization of the basal ganglia (BG) is often defined according to one of two opposing schemes. The first proposes multiple, essentially independent channels of information processing.

On connected Boolean functions
Various classes of Boolean functions are introduced: connected, strongly connected, geodetic, convex, strongly convex and concordant. They are characterized by some properties of the subgraph of the Boolean hypercube induced by the (false) true points of a function.

Independent contributions of structural and functional connectivity: Evidence from a stroke model
Altered functional connectivity is related to severity of language impairment in poststroke aphasia. However, it is not clear whether this finding specifically reflects loss of functional coherence, or more generally, is related to decreased structural ...
