Informed Constrained Spherical Deconvolution (iCSD)
Medical Image Analysis, 2015 Diffusion-weighted (DW) magnetic resonance imaging (MRI) is a noninvasive imaging method, which can be used to investigate neural tracts in the white matter (WM) of the brain.

Magnetic Resonance in Medicine, 2013
The single diffusion tensor model is inadequate for the reconstruction of fiber pathways in brain regions with multiple fiber orientations. To overcome this limitation, constrained spherical deconvolution has been proposed. A high reliability of constrained spherical deconvolution is, however, a pre‐requisite for its use in clinical applications ...

Autism Research, 2013
Autism spectrum disorders (ASDs) are associated with a marked disturbance of neural functional connectivity, which may arise from disrupted organization of white matter. The aim of this study was to use constrained spherical deconvolution (CSD)‐based tractography to isolate and characterize major intrahemispheric white matter tracts that are important ...

Estimation of Uncertainty in Constrained Spherical Deconvolution Fiber Orientations
2008 5th IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2008Constrained spherical deconvolution (CSD) is a new reconstruction technique that extracts white matter fiber orientations from diffusion weighted MRI data of the brain. However, since these orientations are estimated from noisy data, they are subject to errors, which propagate during fiber tractography.

NeuroImage, 2014 Constrained spherical deconvolution (CSD) has become one of the most widely used methods to extract white matter (WM) fibre orientation information from diffusion-weighted MRI (DW-MRI) data, overcoming the crossing fibre limitations inherent in the diffusion tensor model.

Basal ganglia network by constrained spherical deconvolution: A possible cortico‐pallidal pathway?
Movement Disorders, 2014AbstractIn the recent past, basal ganglia circuitry was simplified as represented by the direct and indirect pathways and by hyperdirect pathways. Based on data from animal studies, we hypothesized a fourth pathway, the cortico‐pallidal, pathway, that complements the hyperdirect pathway to the subthalamus.

The periaqueductal gray (PAG) is a relevant neuronal station situated in the midbrain, which play a pivotal role in triggering behavioral responses to stressful stimuli, such as pain or threat. Current knowledge concerning PAG functions is based on several tract-tracing studies conducted on animals, which unveiled PAG connectivity to both cortical and ...
