Time-series correlation analysis of BOLD fMRI data was performed based on the mental process of cognitive control

Abstract

This essay explores the pivotal role of blood oxygen level-dependent functional magnetic resonance imaging (BOLD fMRI) in advancing neuroimaging research, with a focus on its application in analyzing two distinct tasks: the Flanker Task and the Board Task. The study outlines essential preprocessing steps for brain imaging data and employs the General Linear Model (GLM) for statistical analysis. The Flanker Task assesses cognitive control, requiring participants to respond to arrow stimuli. Brain activation maps reveal significant activity in the prefrontal cortex, parietal lobules, and occipital lobes during this task. The Board Task, designed to study motor control, involves participants tapping a flashing checkerboard. The analysis identifies activation in the occipital V1 region, parietal cortex, and prefrontal cortex.
