The nature of the signal undershoot observed in the inter-stimulation intervals in fMRI studies using a block paradigm consisting of alternating periods of visual stimulation and rest was investigated using the following single shot EPI sequences: gradient echo (GRE), spin echo (SE), spin echo with

## Abstract FMRI has revealed the presence of correlated lowβfrequency cerebroβvascular oscillations within functional brain systems, which are thought to reflect an intrinsic feature of largeβscale neural activity. The spatial correlations shown by these fluctuations has been their identifying fea
The blood oxygen level-dependent (BOLD) magnetic resonance signal of functional brain cortices is dominated by very low frequency (VLF) fluctuations in anesthetized child patients. The temporal synchrony of the BOLD signal is also higher in anesthetized children compared with awake adults. The origi
