报告题目:In-vivo Mapping of  Structural Connectivity in the Human Brain

报告摘要:Knowledge of functional  roles of brain areas and associated connections are of critical importance in  the understanding of normal brain functions as well as brain abnormalities. The  connectivity pattern is formed by structural links of synapses and associated  fiber pathways and the underlying causal relationships measured as  cross-correlations or coherence. Neural activity, and by extension neural codes,  are constrained by connectivity. It is so shallow and clear to understand the  links of neuronal connection with brain activity and consequent brain  functions.For decades  neuroscientists exhibited little interest in the connections due to the limit of  non-invasive technique. With the advent of diffusion MRI, a technique based on  the measurement of water molecular diffusion, the architecture of human neuronal  bundles can be more thoroughly scrutinized in vivo. The neuronal microstructure  as measured by diffusion imaging appears the importance of the connection in the  proper transfer of information among brain regions. New studies have shown its  close coupling with the cognitive functions, not only behavioral deviation or  dysfunction but also personal variation in cognitive performance such as memory  performance, language learning and reading ability.Within the lecture, I  will review the development of diffusion MRI techniques including  diffusion-weighted image, q-space image, DTI, HARDI, diffusion spectrum image  and related post-processing method and tractography. Further applications based  on the derived structural connectivity will be discussed as well.报告人简介请见附件简历。
