Inside the Mind: How fMRI Maps the Brain in Action
fMRI is a word often heard in discussions about brain research, psychology, and medical imaging. But what is fMRI exactly? And what makes it such a pioneering instrument for comprehending not just the appearance of the brain but also its functioning? Functional Magnetic Resonance Imaging, or fMRI for short, is a non-invasive imaging technique that lets researchers and medical professionals view what the brain is doing in real-time. It displays dynamic activity by showing how various brain areas “light up” in reaction to ideas, pictures, emotions, and actions. fMRI goes beyond the static anatomical photographs of a conventional MRI. Knowledge of fMRI is not limited to researchers. fMRI is an incredible step towards understanding the inner workings of the human mind, and it can transform our understanding of mental health and memory. How fMRI Works: Brain Activity via Blood Flow A basic yet potent principle is at the heart of all fMRI systems: the brain requires more oxygen when a portio...
