In this work we studied the dynamics of functional connectivity within the default mode network using high temporal sampling rate (TR=350 ms) Simultaneous MultiSlice (SMS) Resting-state fMRI. We performed wavelet coherence analysis in two frequency bands: 0.01-0.1 Hz and above 0.1 Hz. Our results indicate that functional connectivity occurs at multiple frequency bands including those above 0.1 Hz that are commonly ignored in rsfMRI studies and exhibits dynamic changes within time scales of seconds to minutes.
