Hi Freesurfer experts I have a question about designing an event related task. We are designing a task for fear conditioning. Each stimuli presentation lasts 4 seconds. My question is if we set the TR to 2 (which is a multiply of 4), will it make the paradigm to have more power in signal detection? Or does it not matter if the TR and stimuli presentation be a multiply of each other or not? I appreciate if you give me your comments on that.
Thanks a lot Mona Zahra (Mona) Nasiriavanaki Postdoctoral Research Fellow Martinos Center for Biomedical Imaging Massachusetts General Hospital 149 13th Street, 149-2615 Charlestown, MA, USA, 02129
