We used a picture encoding task (block design) that involved memorization of indoor and outdoor scenes along with an appropriate resting task.
Here, we used a modified version of Catmur and Heyes' (2011) task with the addition of baseline trials (Wiggett et al. 2013) in which the cue to lift is accompanied by a pixelated image of the resting task-irrelevant hand.
Using a randomized waitlist control design, 85 children were randomly allocated to a training or waitlist condition and completed pre- and post-training assessments of overt behavior, trained and untrained cognitive task performance, and resting and task-related EEG activity.
All participants will complete the same fMRI tasks collected during the first MRI visit (e.g., implicit facial expression recognition, emotional go/no go, encoding and retrieval, and resting state tasks).
During rest tasks, participants explicitly lay relaxed.
(2017) use dense sampling of resting and task fMRI within individuals to demonstrate that patterns of correlation in resting fMRI are closely aligned with functional architecture as identified using task fMRI.
For each type of EPI image, 30 timepoints were acquired while the subject was resting (no task).
Kannurpatti and Biswal (2008) proposed the use of resting state ("task-free") fMRI to derive a measure of vascular reactivity.
It was found that, compared to the pre-task resting period, the post-task resting fcMRI revealed a significantly higher (p = 0.002, N = 24) cross correlation coefficient (CC) between left and right motor cortices.
In a double-blind counter-balanced design, participants ingested placebo or MPH and in a magnetic resonance imaging scanner performed: a six-minute pre-task resting scan, a fatiguing handgrip task during scanning, and then a six-minute post-task resting scan.
