BackgroundResearch ethics and the measures deployed to ensure ethical oversight of research are vested with extremely important ethical and practical goals. Accordingly, these measures need to function effectively in real-world research and to follow high level standards.MethodsWe examined approved consent forms for Magnetic Resonance Imaging and functional Magnetic Resonance Imaging studies approved by Canadian research ethics boards .ResultsWe found evidence of variability in consent forms in matters of physical and psychological risk reporting. Approaches used to tackle the emerging issue of (...) incidental findings exposed extensive variability between and within research sites.ConclusionThe causes of variability in approved consent forms and studies need to be better understood. However, mounting evidence of administrative and practical hurdles within current ethics governance systems combined with potential sub-optimal provision of information to and protection of research subjects support other calls for more scrutiny of research ethics practices and applicable revisions.

Following Karni's seminal work, Walker and other researchers have recently provided gradually convincing evidence that sleep is critical for the consolidation-based enhancement (CBE) of motor sequence learning. Studies in our laboratory using a motor adaptation paradigm, however, show that CBE can also occur after the simple passage of time, suggesting that sleep effects on memory consolidation are task-related, and possibly dependent on anatomically dissociable circuits.
