- Who invented fMRI?
- How does fMRI work?
- How is image contrast produced by BOLD fMRI?
- Why does the BOLD signal increase during activation? It seems like it should decrease since more oxygen is being used up.
- Does the BOLD response result from the firing of nerve cells?
- What is the best pulse sequence to use for BOLD fMRI?
- How do you design a BOLD/fMRI study?
- Why do you have to do an "on-off" comparison? Why not just measure the absolute BOLD signal instead?
- What is the best way to identify the motor cortex using fMRI?
- What about fMRI of the visual system?
- What paradigms do you use to test language function prior to surgery?
