Dear CONN members. 

I wonder why we use the bandpass filter range as [0.008 ~ 0.09 Hz] for resting state fMRI.

Some studies reported that the reason was to reduce low-frequency drift and noise effects.


However, I couldn't find more exact explanation based on BOLD signal or physiology or an anything.

I think the best explanation is existed about this.

Because the range was choosen as the defalut value in the CONN, and I guess some discussion had been held.

Is there anyone who can explain this?
