Cerebral slow vasomotion, termed 0.1-Hz oscillation,
might confound neurovascular coupling in resting-state
fMRI BOLD signal. To explore neural contribution to the
0.1-Hz oscillation, simultaneous fMRI and full-band LFP
recording in rat cortex were performed. Coherence
analyses on the concurrent BOLD, infraslow LFPs and
high-frequency LFPs revealed close relationship between
each others at ~0.1 Hz during spontaneous oscillation.
