We have decided to make a number of changes to the MRI protocol based on our analyses of the first 6 months of data. In particular, we are going to reduce the frequency of the structural and DTI acquisitions (because, as expected, we don't see much in the way of changes over time). In addition, after acquisition of 14 sessions on a working memory task, I have decided to reduce its frequency and add another task fMRI paradigm that will be collected once a week.
My question for you is: What should I do next? I have several things in mind, but I want to see if the community can do even better. If you have an idea for task fMRI paradigm where a large number of sessions from a single individual would be useful, please email me (poldrack at utexas dot edu) with a brief proposal that outlines specifically why it would be interesting to perform the task repeatedly on a single person and how many sessions it would require. I will work with the winner to implement the task, and that person will of course be offered coauthorship on any papers that include those data. There are two requirements:
- Each session of the task must be accomplished within a single 10-minute imaging run.
- The task cannot require any special response or stimulation devices (for stimulation we have video projection and headphones; for response, we have several button boxes available as well as eye tracking, noise-cancelling microphone, and physiological monitoring).
I look forward to hearing your ideas!
