Description:

This paper describes the potential pitfalls of time of day on MRI results, giving specific examples regarding the potential errors. The paper further argues that developers of research designs need to take all relevant processes into account if their results are to have validity. In particular, the paper points out how cortisol can cross the blood-brain barrier and bind to receptors in the hippocampus and frontal lobe which can then have an impact on the neural activation/deactivation process.

From the Paper:

"Developers of research designs need to take all relevant processes into account if their results are to have validity. Many researchers conducting functional magnetic resonance imaging (MRI) tests fail to take the time of day into consideration. This can lead to error given that cortisol levels are different throughout the course of a day. This is important because cortisol can cross the blood-brain barrier and bind to receptors in the hippocampus and frontal lobe. This can then have an impact on the neural activation/deactivation process, meaning the BOLD (Blood Oxygen level dependent) in the fMRI study and produce results that will not be properly interpreted unless the time of day is included as a variable..."
