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.
The lecture for this section can be viewed here.
Please read Chapter 7 of the Huettel, Song, & McCarthy textbook on the BOLD signal
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.
