fmri, block design: length of "On" and "Off" periodes ?
Hello,
I'm planning some fmri research and I wonder why often the blocks of stimulation and nothing (or called base level or resting state) have the same length

If I let -maybe- a flickering checkerboard about 16 seconds on, as my "ON" period... then I should not need further 16 seconds resting state? DO I?

The BOLD-related effects should be away after about 2 seconds?

Thanks
Rudolfo
