The raters did not assess the scans in consecutive order according to subject or date of scanning.
This fact may yet become the subject of philosophical inquiry a scan of every Gmail message ever sent taught the machine that the proper response to ambiguity is an outpouring of love?—but, for Google, it was a bug rather than a feature.
Although these RSNs appear to be relatively enduring phenomena [5], they may also demonstrate relevant changes in their functional connectivity depending on active changes in the brain state of subjects during scanning.
While these 'resting-state networks' may be relatively enduring phenomena, other evidence suggest that dynamic changes in their functional connectivity may also emerge depending on the brain state of subjects during scanning.
While efforts so far have focused on clarifying the physiological basis and spatial replicability of these signals across studies [8], [9], [16] [20], it is less clear how changes or differences in the behavioral state of subjects during scanning may be represented in these so-called 'resting-state networks' (RSNs).
A Velcro band held the probe assembly securely to the forehead of subjects during scanning and extended from ear to ear horizontally and from hairline to eyebrows vertically.
Debriefing of our subjects after scanning revealed that all became aware of the emotional content of the stimuli over the course of the experiment.
For obese subjects (>90 kg), increase of scanning time (time per bed position) rather than increase of FDG activity is recommended to improve image quality.
During the entire time of scanning, subjects were shown a silent movie with underwater scenery free from any sudden or salient visual events in order to control for attentional load between subjects.
The investigator was blinded to subject identification, date of scan, and training status, as well as their genotypes, in both baseline and after training analyses.
BMI can also have an effect on the average standing height of the subject above the scanning table and this can result in a variation in image dimension across the table in fan beam systems.
