Previous fMRI studies have demonstrated a number of functional networks in the brain. The introduction of simultaneous multi-slice (SMS)-imaging has allowed a larger volume coverage of the brain to be acquired with a shorter repetition time (TR), increasing temporal resolution so that dynamic connectivity (DC) measures are more achievable. Here, we use sub-second SMS-imaging to assess DC in sensorimotor networks during a self-paced finger tap experiment, and demonstrate changes in DC during individual button presses.
