Measurement and Signal

Measuring in-vivo brain activity from humans is an extraordinary feat. How do scanners work? and what exactly are we measuring?

In this section, we will provide a very introductory overview of the basics of MR Physics and the physiology underlying the signal we are measuring with BOLD fMRI.

Videos

There are many fantastic lectures on this topic. We recommend watching the short videos by Tor Wager and Martin Lindquist from their Principles of fMRI Coursera class.
