Brain analyses using functional magnetic resonance imaging fMRI viewed from experimental psychology

Abstract

Functional magnetic resonance imaging fMRI is the way to study neural correlates of consciousness involving perception, memory, learning, thinking and affection through measuring cardio vascular response using the principle of nuclear magnetic resonance. By estimating differential functions between oxy-and deoxy-hemoglobin in the blood, we can calculate BOLD signals and obtain a brain image which indirectly suggest brain s local activation induced by the current task. It should be noted that the activation images are assumed not direct evidence reflecting brain s neuronal activities. Moreover, we briefly discussed on the parameters for imaging, image analyses using SPM and restraints on the participant.
