Designing studies
There are many important issues that need to be considered when designing an fMRI experiment, at many different levels.
General principles

Choosing your MRI acquisition
You'll probably use our default MRI sequences. However, you might want to use another protocol (for example, to change the number of slices) but you must discuss it with the Radiographers. If you're doing anything exotic, you should also contact the Physicists (Marta, Stefan or Rhodri).

Useful tips

Using scanner sync to synchronise your stimulus delivery program with the scanner
Transforming stimulus size in pixels to/from visual angle in degrees. Useful for matching stimulus size between behavioural testing and the scanner.
