  • Two-Tensor Model-Based Bootstrapping on Classified Tensor Morphologies: Estimation of Uncertainty in Fibre Orientation and Probabilistic Tractography 
    Nagulan, R.; Simmons, A.; Bertoni, M.; Ali, H. (ElSEVIER/Megnetic Resonance Imaging, 2013-02)
    In this manuscript, fast and clinically feasible model-based bootstrapping algorithms using a geometrically constrained two-tensor diffusion model are employed for estimating uncertainty in fiber orientation. A Monte-Carlo-based ...
  • Structural connectivity asymmetry in the neonatal brain 
    Nagulan, R.; Graboi, Anne Rifkin; Fortier, M.V.; Chong, Y.S.; Kwek, K.; Saw, Seang-Mei; Godfrey, Keith M; Gluckman, P.D.; Meaney, M.J.; Qiu, A. (ElSEVIER/NeuroImage, 2013-07)
    Asymmetry of the neonatal brain is not yet understood at the level of structural connectivity. We utilized DTI deterministic tractography and structural network analysis based on graph theory to determine the pattern of ...
  • Abnormalities of cortical thickness, subcortical shapes, and white matter integrity in subcortical vascular cognitive impairment. 
    Thong, Jamie Yu Jin; Du, Jia; Nagulan, R.; Dong, Yanhong; Soon, Hock Wei; Saini, Monica; Tan, Ming Zhen; Ta, Anh Tuan; Chen, Christopher; Qiu, A (Wiley Online Library/Human Brain Mapping, 2014-05)
    Subcortical vascular cognitive impairment (sVCI) is caused by lacunar infarcts or extensive and/or diffuse lesions in the white matter that may disrupt the white matter circuitry connecting cortical and subcortical regions ...
  • Multi-Label Segmentation White Matter Structures: Application to Neonatal Brains. 
    Nagulan, R.; Qiu, A. (ElSEVIER/NeuroImage, 2014-11-15)
    Accurate and consistent segmentation of brain white matter bundles at neonatal stage plays an important role in understanding brain development and detecting white matter abnormalities for the prediction of psychiatric ...
  • Adaptation of brain functional and structural networks in aging 
    Lee, A.; Nagulan, R.; Tuan, T.A.; Chen, S.H.; Qiu, A. (Public Library of Science/PLOS ONE, 2015-04-15)
    The human brain, especially the prefrontal cortex (PFC), is functionally and anatomically reorganized in order to adapt to neuronal challenges in aging. This study employed structural MRI, resting-state fMRI (rs-fMRI), and ...
  • Developmental synchrony of thalamocortical circuits in the neonatal brain. 
    Poh, J.S.; Li, Y.; Nagulan, R.; Fortier, M.V.; Chong, Y.S.; Kwek, K.; Saw, S.M.; Gluckman, P.D.; Meaney, M.J.; Qiu, A. (ElSEVIER/NeuroImage, 2015-08-01)
    The thalamus is a deep gray matter structure and consists of axonal fibers projecting to the entire cortex, which provide the anatomical support for its sensorimotor and higher-level cognitive functions. There is limited ...
  • A tourist satisfaction analysis of Eastern province, Sri Lanka 
    Jeyamugan, T.; Cooray, T. M. J. A.; ampath Kappagoda, U.W.M.R. (7th Annual Science Research Sessions-2018, 2018)
    Tourism is a major source of income in Sri Lanka. Tourism is defined as marketing of enjoyable and other features of an attractive location including the services for thehappiness of tourists. The eastern province is one ...
