Optogenetic Functional MRI [PDF]
Journal of Visualized Experiments, 2016 The investigation of the functional connectivity of precise neural circuits across the entire intact brain can be achieved through optogenetic functional magnetic resonance imaging (ofMRI), which is a novel technique that combines the relatively high spatial resolution of high-field fMRI with the precision of optogenetic stimulation.

An Evaluation of Distinct Volumetric and Functional MRI Contributions Toward Understanding Age and Task Performance: A Study in the Basal Ganglia [PDF]
, 2007 Prior work by our group and others has implicated the basal ganglia as important in age-related differences in tasks involving motor response control. The present study used structural and functional MRI approaches to analyze this region of interest (ROI)

Spatio-temporal wavelet regularization for parallel MRI reconstruction: application to functional MRI [PDF]
, 2013 Parallel MRI is a fast imaging technique that enables the acquisition of highly resolved images in space or/and in time. The performance of parallel imaging strongly depends on the reconstruction algorithm, which can proceed either in the original k ...

Decomposition of Spontaneous Brain Activity into Distinct fMRI Co-activation Patterns
Frontiers in Systems Neuroscience, 2013 Recent fMRI studies have shown that analysis of the human brain’s spontaneous activity may provide a powerful approach to reveal its functional organization. Dedicated methods have been proposed to investigate co-variation of signals from different brain
