"Webb10 feb. 2024 · fMRI is a hemodynamic method that measures the amount of deoxygenated blood in parts of the brain (Ward, 2016). The amount of deoxygenated blood gives off a BOLD signal (Blood-Oxygen-Level Dependent) and convert into voxels (form of pixels) which allow us to see a 3D image of the brain and to track the neural activity (Martin & … " - Pros of fmri

Functional magnetic resonance imaging - PubMed

WebbFunctional magnetic resonance imaging (fMRI) allows the exploration of the local vascular response, and indirectly the coupled neural response to particular stimuli. It utilizes differences in the paramagnetic properties of oxyhemoglobin and deoxyhemoglobin, known as blood oxygen level-dependent (BOLD) contrast, to generate images of cerebral … WebbMRI (often called structural MRI) reveals brain anatomy, while fMRI reveals brain function, often in the form of neural activity. For this reason, fMRI is very useful for neuroscience and clinical research, while MRI is traditionally used for clinical characterization in the same manner as CT scans.

WebbThe first fMRI studies validated the technique against brain activity known, from other techniques, to be correlated to tasks. By the early 2000s, fMRI studies began to discover novel correlations. Still their technical disadvantages have spurred researchers to try more advanced ways to increase the power of both clinical and research studies. WebbThe advantages and disadvantages of using functional magnetic resonance imaging …

Webbthere are several disadvantages of PET that have led to its being surpassed by fMRI as the most widely used indirect measure of brain activity.
