Eye Movement Quantification in Functional MRI Data by Spatial Independent Component Analysis
نویسندگان
چکیده
We present a novel analysis to quantify the eye movement from functional magnetic resonance (fMRI) data without the aid of dedicated eye-trackers. We show that by using the parts of the functional image data that contain the motion artefacts of the subject’s eyes and by applying spatial independent component analysis to it, it is possible to detect eye movement and to estimate the point of gaze at the time of the data acquisition.

Improving the Performance of ICA Algorithm for fMRI Simulated Data Analysis Using Temporal and Spatial Filters in the Preprocessing Phase
Introduction: The accuracy of analyzing Functional MRI (fMRI) data is usually decreases in the presence of noise and artifact sources. A common solution in for analyzing fMRI data having high noise is to use suitable preprocessing methods with the aim of data denoising. Some effects of preprocessing methods on the parametric methods such as general linear model (GLM) have previously been evalua...
متن کاملSpatial Independent Component Analysis for Multi-task Functional MRI Data Processing
Multi-task in one epoch usually exists in our life, but the brain functional activation response is few analyzed. One key problem is that the multi-task response data processing has not been addressed. In this paper, spatial independent component analysis (sICA) is presented to separate the different response of the complex visual-movement task by analyzing the unmixing matrices temporal compon...

Background: Caffeine is a kind of methylxanthine whose consumption can promote the cognitive and executive functions of the human brain. Objectives: In this study, we seek to investigate the effect of drinking coffee on the period of the eye movement fixation component. Materials and Methods: The research was of the quasi-experimental type. 60 subjects were randomly divided into two group...
متن کاملTemporal and Spatial Independent Component Analysis for fMRI data sets embedded in a R package
For statistical analysis of functional Magnetic Resonance Imaging (fMRI) data sets, we propose a data-driven approach based on Independent Component Analysis (ICA) implemented in a new version of the AnalyzeFMRI R package. For fMRI data sets, spatial dimension being much greater than temporal dimension, spatial ICA is the tractable approach generally proposed. However, for some neuroscientific ...
متن کاملFeature selection using genetic algorithm for classification of schizophrenia using fMRI data
In this paper we propose a new method for classification of subjects into schizophrenia and control groups using functional magnetic resonance imaging (fMRI) data. In the preprocessing step, the number of fMRI time points is reduced using principal component analysis (PCA). Then, independent component analysis (ICA) is used for further data analysis. It estimates independent components (ICs) of...
