Resting State fMRI-Guided Fiber Clustering [chapter]

Bao Ge, Lei Guo, Jinglei Lv, Xintao Hu, Junwei Han, Tuo Zhang, Tianming Liu
2011 Lecture Notes in Computer Science  
Specifically, we represent the functional identity of a white matter fiber by two resting state fMRI (rsfMRI) time series extracted from the two gray matter voxels to which the fiber connects.  ...  Fiber clustering is a prerequisite step towards tract-based analysis of white mater integrity via diffusion tensor imaging (DTI) in various clinical neuroscience applications.  ...  gray matter and white matter are relatively low.  ...

2005 Electronic Imaging and Multimedia Technology IV  
A novel method providing a supervised processing of medical image for segmentation is presented.  ...  In the processing, both texture and gray variation information are used inside the tissue regions, and only gradation information is used near the edges of regions.  ...  Different area has its own texture features that denote different tissue types (head, the brain white matter, the brain gray matter). 2.  ...

Striola magica. A functional explanation of otolith geometry

Mariella Dimiccoli, Benoît Girard, Alain Berthoz, Daniel Bennequin
2013 Journal of Computational Neuroscience  
We propose a mathematical and computational model that explains the necessity of this amazing geometry for the striola to be able to carry out its function.  ...  Otolith end organs of vertebrates sense linear accelerations of the head and gravitation. The hair cells on their epithelia are responsible for transduction.  ...  They increase from white over gray to black and were normalized with respect to the largest density found on one of the epithelia.  ...

Large-scale evaluation of ANTs and FreeSurfer cortical thickness measurements

Nicholas J. Tustison, Philip A. Cook, Arno Klein, Gang Song, Sandhitsu R. Das, Jeffrey T. Duda, Benjamin M. Kandel, Niels van Strien, James R. Stone, James C. Gee, Brian B. Avants
2014 NeuroImage  
ANTs is shown to have a higher predictive performance than FreeSurfer for both of these measures.  ...  Many studies of the human brain have explored the relationship between cortical thickness and cognition, phenotype, or disease.  ...  Since cortical thickness estimation only requires the cortical gray and white matter, the deep gray and white matter (both labels and posterior maps) are combined to form a single "white matter" set.  ...
