題目(Title) Estimation and analysis of human brain functional networks
概要(Abstract) In this presentation, I will introduce two of my previous studies; 1) method development for estimating human brain functional networks from multimodal non-invasive neuroimaging data and 2) characterization of the dynamics human brain functional networks using network analysis methods. The first study applied state space modeling and variational Bayesian techniques to the estimation problem. Our method allows reasonably estimating distributed current source activities and their directed functional connectivity across the whole brain, from Magnetoencephalography (MEG), functional magnetic resonance imaging (fMRI), and diffusion MRI data. The second study focused on temporal fluctuations in the modularity of human brain functional networks measured with resting-state fMRI data. This study demonstrated how global patterns of functional connectivity change while fluctuating modularity and the extent to which simulation of large-scale brain activity can replicate our empirical findings.

題目(Title) Estimation and analysis of upper limb motion based on skin deformation
概要(Abstract) The upper limb plays an important role in the manipulation and grasping of daily life objects. Since the upper limb motions and human dexterity have a strong relationship, the motion estimation and analysis are necessary tasks. In my research, "skin deformation" is used for the input source of the estimation and analysis. The skin deformation provides the activities of various body tissues such as muscles, tendons, and bones. In this presentation, I will introduce the estimation methods of the upper limb motions based on the skin deformation. The characteristics and usefulness of the skin deformation are shown with some results of experiments. Besides, I will also introduce the potential of the skin deformation for motion analysis with an example of the rehabilitation application.
