RT Journal Article SR Electronic T1 Overview of potential procedural and participant-related confounds for neuroimaging of the resting state JF Journal of Psychiatry and Neuroscience JO J Psychiatry Neurosci FD Canadian Medical Association SP 84 OP 96 DO 10.1503/jpn.120059 VO 38 IS 2 A1 Niall W. Duncan A1 Georg Northoff YR 2013 UL http://jpn.ca/content/38/2/84.abstract AB Studies of intrinsic brain activity in the resting state have become increasingly common. A productive discussion of what analysis methods are appropriate, of the importance of physiologic correction and of the potential interpretations of results has been ongoing. However, less attention has been paid to factors other than physiologic noise that may confound resting-state experiments. These range from straightforward factors, such as ensuring that participants are all instructed in the same manner, to more obscure participant-related factors, such as body weight. We provide an overview of such potentially confounding factors, along with some suggested approaches for minimizing their impact. A particular theme that emerges from the overview is the range of systematic differences between types of study groups (e.g., between patients and controls) that may influence resting-state study results.
