Executive control is a complex high-level cognitive function that relies on distributed brain
circuitry. We propose that the anterior insular cortex plays an under-appreciated role in …

Healthy aging (HA) is associated with certain declines in cognitive functions, even in
individuals that are free of any process of degenerative illness. Functional magnetic …

The construction of a meaningful graph topology plays a crucial role in the effective
representation, processing, analysis, and visualization of structured data. When a natural …

A key challenge in neuroscience and, in particular, neuroimaging, is to move beyond
identification of regional activations toward the characterization of functional circuits …

Understanding the neural substrates of depression is crucial for diagnosis and treatment.
Here, we review recent studies of functional and effective connectivity in depression, in …

Over the past 20 years, neuroimaging has become a predominant technique in systems
neuroscience. One might envisage that over the next 20 years the neuroimaging of …

Functional Magnetic Resonance Imaging (fMRI) studies have become increasingly popular
both with clinicians and researchers as they are capable of providing unique insights into …

The insula is a brain structure implicated in disparate cognitive, affective, and regulatory
functions, including interoceptive awareness, emotional responses, and empathic …

This technical note introduces a dynamic causal model (DCM) for resting state fMRI time
series based upon observed functional connectivity—as measured by the cross spectra …

There is great interest in estimating brain “networks” from FMRI data. This is often attempted
by identifying a set of functional “nodes”(eg, spatial ROIs or ICA maps) and then conducting …
