MRI - shows you brain structures using magnetic field - good for structure, not good for activity tho. fMRI - can show you what areas of the brain are active using the idea that blood flow and activity are regulated - looks at blood flow composition to tell you which brain areas are active vs which ones are not - good for activity!

The BOLD signal that underlies most fMRI applications is essentially a qualitative signal, because it depends in a complex way on the combined physiological changes of blood flow and oxygen metabolism. An alternative MRI method called arterial spin labeling (ASL) is a tool for measuring blood flow changes directly. The main difference between MRI and fMRI is whereas structural MRI imaging shows the difference between types of tissues at high resolution with respect to space, fMRI shows the difference between the tissues with respect to time. An MRI machine. One key difference between MRI and fMRI is that MRI can generate static images that may be reviewed later for information about the inside of the patient’s body. In an fMRI study, the result is a real-time log of brain activity. Functional MRI or fMRI follows the same principle as regular MRI. However, during a functional MRI procedure, the scanner and computer take photos of the brain over time.
Med fMRI kan man också studera de förändringar som uppstår i hjärnan efter en skada, exempelvis en stroke eller en amputation.

Part V deals with practical applications of the technique in the field of neuroscience and in clinical practice.
Background. Functional MRI (fMRI) is a non-invasive technique for the study of brain function that utilizes changes in blood flow and volume accompanying brain activation. The different magnetic properties of oxygenated and deoxygenated blood yields signal changes in the MRI images.
Learn about fMRI imaging and find out about the connection between fMRI and lie detection. Advertisement By: Stephanie Watson An fMRI scan Do you need an MRI? Here's how much it will cost and why. Shutterstock Magnetic resonance imaging -- commonly called just MRI -- is the next best thing to magic.
用mri / fmri进行现场工作也不会发生，因为它们不够便携。 用脑电图进行实验也不需要太多麻烦——有时只需戴上耳机，检查数据质量。 自动计算的指标还可以通过脑电图快速了解人类行为。
Magnetic resonance imaging (MRI) is a type of medical imaging that uses strong magnetic fields to produce images of organs in the body. För- och nackdelar med fMRI. fMRI intervenenar inte med hjärnans funktioner, utan mäter bara den naturliga förändringen av syrehalten i hjärnans olika delar, och de starka magnetfält som används inom MRI-teknik har inte visat ha några skadliga effekter på biologisk vävnad.[8] For fMRI, the same things happen as with MRI – the energy emitted from the relaxation of protons is measured – but the calculations are instead aimed at determining how the amount of oxygenated blood flow changes. The measurement of signals is different for both MRI and fMRI. For instance, an MRI analyzes the hydrogen nuclei of the water molecule whereas a functional MRI measures the levels of oxygen.

To start with, if you come from fMRI background, there are few important differences between the haemodynamic imaging (fMRI, PET) and neurophysiological imaging (MEG, EEG) approaches, all closely related to each other: 1. Timing aspect. In MEG/EEG, you can follow brain activation with millisecond precision. fMRI refers to a set of techniques within MRI imaging and stands for “functional MRI”. Therefore, fMRI is part of MRI and not distinct from it.
MRI is designed for revealing the peculiarities of anatomical structure inside a human organism, including those in the human brain.
