Emerging research in brain connectivity reveals new understanding of neurological disorders
Date:6/7/2011

s a range of informative and probing articles on evolving imaging technologies that allow researchers to study the structural and physiological connections between brain regions, and healthy and disease states.

An insightful review article by Marcus Raichle, Washington University School of Medicine (St. Louis, MO), called "The Restless Brain," presents a detailed look at the results derived from modern brain imaging techniques used to study the relationship between spontaneous brain activity and conscious brain function and to understand the integration of major brain systems during a task compared to when the brain is at rest.

An article by Andrzej Jesmanowicz, Andrew Nencka, Shi-Jiang Li, and James Hyde (Medical College of Wisconsin, Milwaukee), introduces an improved method for accelerating the acquisition of multislice MRI brain connectome data. This article, in the new field of simultaneous multislice functional brain imaging, describes a method for acquiring images of an increased number of brain slices in a short time to shorten the total examination time for clinical fMRI and fcMRI. It also represents an exciting advance in basic neuroscience, as simultaneously acquired brain slices would allow researchers to study the relative timing of brain activities, a subject of intense interest in the neuroscience field.

Karl Friston's (University College, London, United Kingdom) controversial review of the field of brain imaging and its use in studying brain connectivity traces the history of functional connectivity in the brain and provides an overview of current efforts to model neurologic networks. Viktor Jirsa and Young-Ah Rho (Florida Atlantic University, Boca Raton), and Randy Anthony McIntosh (Rotman Research Institute of Baycrest Center, Toronto, ON, Canada) present data demonstrating a network-level mechanism in which transient neuroelectric synchronization of two distinct brain regions is predictive of blood oxygen level depende
