Basics of fMRI

A brief (under 15 mins) tutorial on the basics of fMRI for the cognitive neuroscience bitesize series. Covers the physics of MRI; structural and functional imaging; the haemodynamic response and how we can link it to cognitive processes. Aimed for university students in psychology and neuroscience.

pity the banner that pops up at 13:44 partly covers the summary of this clever presentation. (subscribed anyway)

Very informative, thank you! I was wondering if anyone would be able to explain the term "neurovascular coupling" in relation to fMRI? I don't fully understand how it relates to the mechanics of fMRI. Thank you!

the BOLD signal comes from that influx of fresh (oxygenated) blood after neural activity. there's a difference in magnetism between fresh and 'used' (deoxygenated) blood and this difference is a natural contrast agent, so to speak, that the scanners (and more specifically pulse sequences) are designed to exploit. it's a small-ish and pretty noisy signal, but it works!
