Mapping of intrinsic high frequency (> 0.5 Hz) resting
state connectivity has been demonstrated in recent
studies in motor and visual cortex. In this study we use
multi-slab echo volumar imaging with 136 ms temporal
resolution to compare resting state connectivity in 6
major resting state networks at frequencies below 0.3 Hz
and at frequencies between 0.5 and 3.6 Hz. The high
frequency connectivity in the brain corresponds strongly
to connectivity observed within the low frequency RSNs.
This preliminary study establishes resting state
connectivity at frequencies > 0.5 Hz in multiple major
RSNs.
