Dear Alfonso,
 
I used CONN-fMRI to explore the functional connectivity in a working memory task and a high-pass filter [0.008 inf] was used as suggested by you in a response in the forum. However, a reviewer criticized that I should used the filter of [0.008HZ, 0.25HZ] because I adopted the block design and each block lasts 2s. Do you have any suggestion about how to choose the filter of  signal frequency for task-based analyses?
 
Thanks,
Yang Yang
