Abstract The Human Connectome Project consortium led by Washington University,
University of Minnesota, and Oxford University is undertaking a systematic effort to map …

Background The human brain presents a puzzling and challenging paradox: Despite a fixed
anatomy, characterized by its connectivity, its functional repertoire is vast, enabling action …

Studies of large-scale brain organization have revealed interesting relationships between
spatial gradients in brain maps across multiple modalities. Evaluating the significance of …

Inter-areal coherence between field potentials is a widespread phenomenon in cortex.
Coherence has been hypothesized to reflect phase-synchronization between oscillators and …

Visual cortical areas subserve cognitive functions by interacting in both feedforward and
feedback directions. While feedforward influences convey sensory signals, feedback …

Cognitive functions rely on the coordinated activity of neurons in many brain regions, but the
interactions between cortical areas are not yet well understood. Here we investigated …

This Perspective considers the influential notion of a canonical (cortical) microcircuit in light
of recent theories about neuronal processing. Specifically, we conciliate quantitative studies …

The brain is expensive, incurring high material and metabolic costs for its size—relative to
the size of the body—and many aspects of brain network organization can be mostly …

An increasing number of theoretical and empirical studies approach the function of the
human brain from a network perspective. The analysis of brain networks is made feasible by …

Abstract Information processing in the cerebral cortex involves interactions among
distributed areas. Anatomical connectivity suggests that certain areas form local hierarchical …
