Kong, X., & Francks, C. (2017). Differential gene expression associated with frontal and occipital asymmetries of the human brain. Poster presented at the Annual Meeting of the Organization for Human Brain Mapping, Vancouver, Canada.
Abstract
Rightward frontal and leftward occipital asymmetries in human brain (i.e., brain torque) have been consistently reported in postmortem and in vivo neuroimaging studies. Alterations of these asymmetries may be involved in human disorders including stuttering and depression. However, little is known about the genetic determinants of these asymmetries. In the present study, we aimed to explore the genetic basis of frontal and occipital asymmetries by combining a large sample of MRI images (N = 2326) and a high-resolution gene expression database (Allen Human Brain Atlas, AHBA). -
Huang, L., Yang, Z., Zhou, G., Liu, Z., Dang, X., Kong, X., Wang, X., Zhen, Z., & Liu, J. (2014). FreeROI: an integrated toolbox for region of interest definition and visualization. Poster presented at The 17th National Academic Congress of Psychology, China.
Abstract
With the increasing knowledge for the topography of brain function, neuroimaging studies are moving away from traditional brain mapping towards investigating the response properties of specific brain regions. As a result, region of interest (ROI) approach, which allows one to ask how a region responds to a range of situations and tasks, become an important methodology in neuroimaging. The FreeROI is designed to help ROI analysis by providing versatile tools for defining/manipulating ROIs and calculating a summary time course from the region data. A pipeline for handling big dataset is also included. -
Kong, X., Zhen, Z., & Liu, J. (2014). Measuring Regional Diffusivity Dependency via Mutual Information. Poster presented at IEEE International Symposium on Biomedical Imaging, Beijing.
Abstract
We proposed an improved approach to measuring regional diffusivity dependency with diffusion MRI. Unlike the original approach, the improved metric can detect all types of regional dependencies. Systematical comparison was done. -
Kong, X., Dang, X., & Liu, J. (2014). Large-scale anatomical networks: does node refining matter?. Poster presented at 20th Annual Meeting of the Organization for Human Brain Mapping (OHBM), Hamburg.
Abstract
We evaluated the affects of node refining on the topological properties of constructed large-scale anatomical networks. Significant effects of node-refining on topological metrics in large-scale anatomical network analysis were found, suggesting that node-refining does matter in quantifying anatomical topological properties.
