Abstract

Functional magnetic resonance imaging (fMRI) has become a pivotal tool in brain research, enabling the non- invasive study of brain activity in vivo. By measuring changes in blood oxygenation level-dependent (BOLD) signals, fMRI provides insights into neural processes associated with cognition, behavior, and neurological disorders. This review explores the principles of fMRI, its applications in brain research, including mapping cognitive functions, investigating neural networks, and studying brain diseases, and the technological advancements that have enhanced its resolution and sensitivity. Despite its successes, fMRI has limitations, including issues related to temporal resolution, interpretation of data, and challenges in clinical translation. The future of fMRI in brain research is poised to benefit from advances in imaging techniques, computational methods, and multimodal integration, which will expand its potential for clinical and research applications.
