The predicted phenomenon is confirmed with a hybrid simulation, in which the functional activation was mathematically added to the experimentally acquired rest-period echo-planar imaging data.
We therefore acquired resting state fMRI BOLD data to investigate functional connectivity changes in the default network under propofol sedation.
During both sessions, we first acquired resting state data for 6.5 minutes during which subjects were asked to fixate a fixation cross.
Analysis of the acquired resting-state data was done with the two-stage Ncut group clustering approach and the resulting group RSNs are discussed on their functional relevance, overlap and differences with previous reported resting-state studies.
Having obtained local ethics permission from the Cambridgeshire 2 Regional ethics committee and written consent from participants we acquired resting state fMRI (150 volumes of BOLD data, 5 minutes, TR = 2 s) from a group of 16 adults, 19 52 years old (mean = 34.62, standard deviation = 9.05).
Since the original submission in January, we have acquired resting state spinal fMRI data from a dozen more subjects.
We acquired resting-state fNIRS before and after intense training on the classical orientation discrimination task at a specific location in the right visual field.
We acquired resting fMRI data before and immediately after anodal tDCS applied to the left M1 in a separate group of 10 subjects.
Aliquots of 50 µl were pipetted into a 96-well plate and 100 s of control data (20 readings) were acquired (resting level (R)).
This study used functional magnetic resonance imaging to acquire resting-state scans in 22 migraineurs without aura and in 22 healthy matched controls.
The M-EPI sequence was used to acquire resting state fMRI (R-fMRI) data, and compared to standard EPI at 3T. 3 mm isotropic resolution images were acquired with: 2604 Hz/pixel, matrix size 64×64, RPE = 2, TE = 40 msec, and 36 slices.
