Neuroimaging studies have shown that the brain is functionally organized into several large-scale brain networks. Within these networks are regions that are widely connected to several other regions within and/or outside the network. Regions...
In this study, we investigated the effect of the dynamic changes in brain activation during neurofeedback training in the classification of the different brain states associated with the target tasks. We hypothesized that ongoing...
White matter (WM) fiber bundles change dynamically with age. These changes could be driven by alterations in axonal diameter, axonal density, and myelin content. In this study, we applied a novel fixel‐based analysis (FBA)...
OBJECTIVE The authors recently reported a novel subsecond analysis method of analyzing EEG–functional MRI (fMRI) to improve the detection rate of epileptic focus. This study aims to validate the utility of this method for...
Introduction Parkinson’s disease (PD) shows a variety of visual deficits including visuoperceptual disturbances, however, the neural basis remains unclear. We aimed to clarify clinical and neural features of visuoperceptual disturbances in PD. Methods The...
Visualization of the intrinsic activity of the brain of an individual lying inside the MRI scanner doing nothing (task-free state) as measured by resting state functional magnetic resonance imaging.
An outline of DTI dataset processing pipeline for TBSS analysis as well as probabilistic tractography using FSL. DTI data processing Data preparation Convert dicom files to nifti Use dcm2nii or dcm2niigui from mricron Rename...
Real-time functional MRI is one of my research interests. So from today, I will start compiling a list of papers related to the topic. I will list the paper here after reading it. This...
Quick VIM commands for common editing tasks Search and replace :s/foo/bar/g – change ‘foo’ to ‘bar’ in the current line :%s/foo/bar/g – change ‘foo’ to ‘bar’ in all lines Cut and paste position cursor...
Wordle is an online app for generating “word clouds”, a kind of visual representation for text data. It gives greater prominence to words (e.g., by using larger font size or different font color) that appear more...
Re-posting this one from my old university website. A brief introduction of my graduate research topic. Studies in nonlinear time series analysis have provided reliable techniques for the evaluation of signals from dynamical systems....
NIfTI-1 is a data format proposed by the NifTI (Neuroimaging Informatics Technology Initiative) DFWG (Data Format Working Group) that can be used for storing neuroimaging datasets (e.g. MRI, functional MRI, etc.). This format is adapted from the...
Re-posting this article on real-time functional MRI I wrote several years ago. The technique known as functional magnetic resonance imaging (fMRI) has been extensively used to elucidate the functions of the human brain. Functional...
Just want to share this YouTube video from MicrosoftResearch. It’s just amazing. The idea is to augment the real environment with a virtual one and interact with it. Using four ceiling-mounted Kinects, the entire...
This is a brief guide on how to setup a backup SVN repository using svnsync. I will assume that subversion is already installed and the master repository is located in the machine called remote.com...
Definition Given two random variables X and Y, Pearson’s correlation coefficient ρ is defined as the ratio between the covariance of the two variables and the product of their standard deviations:
Listed below are definitions of some vector or matrix products. I will be needing these definitions in the succeeding posts. Thanks to Jetpack‘s Latex support, I can now include equations in my post.
There are several ways to do this. One is GUI-based. In Fedora Core, use the Places menu in the top panel. Within this menu item, click the ‘Connect to Server…’ sub-menu. This will popup...
I have been using Matlab for almost all of my computing needs. It is very easy to program especially when dealing with matrices. It has also a rich library of graphical interface. You can...
Been out for a while. My last entry was last Nov 2009! It’s more than a year and a half ago! It’s time for a reboot. There are so many things to learn, so...
