Functional Magnetic Resonance Imaging (fMRI) explained | Neuroscience Methods 101

Functional magnetic resonance imaging, or fMRI, is a neuroimaging method which makes brain scans that show regions with increased brain activity. With an MRI scanner oxygen properties of blood can be measured. This gives an indication whether a region is rich or poor in oxygen. Since neurons require oxygen after being activated, this so-called blood-oxygenation-level-dependent response, or BOLD response, is a proxy of brain activity. Blood rich in oxygen, i.e. oxygenated blood, has diamagnetic properties and is slightly repelled within the magnetic field. Deoxygenated blood, which is poor in oxygen, has paramagnetic properties and is slightly attracted by the magnetic field. These differences lead to differences in the MRI signal and reflect activated an less activated regions. References/Resources: Huettel, S.A., Song, A.W., McCarthy, G. (2014).

Narrated by: Miles Wischnewski USE OF STOCK IMAGES AND VIDEOS Occasionally we make use of stock images and videos (pixabay.com or pexels.com). We use these to make our videos more lively (better than looking at a blank screen). These stock videos should not be taken as an exact scientific reflection of the discussed content. In some cases they are not fully accurate. We try to have a high viewing pleasure, while at the same time create as little confusion as possible. Thus we aim to only use them when it is clear that they are not directly related to the discussed content. CHANNEL GOALS The Psyched! channel focuses on providing education about psychology and neuroscience. Here you learn all about human behavior, the mind and the brain. It is our goal to reach everyone, from people who are casually interested to academic researchers. As such we provide simple explanation videos as well as profound lectures.
