AbstractT1-weighted (T1w) imaging is widely used to examine brain structure based on image-derived phenotypes (IDPs) such as cortical thickness, surface area, and brain volumes. The reliability of these IDPs has been extensively explored, mainly focusing on the inter-subject variations, whereas the stability of the within-subject variations has often been overlooked. Additionally, how environmental factors such as time of day and daylight hours impact the structural brain is poorly understood.

AbstractWith the feature of noninvasively monitoring the human brain, magnetic resonance imaging (MRI) has become a ubiquitous means to understand how the brain works. Specifically, T1-weighted (T1w) imaging is widely used to examine the brain structure where the cortical thickness, surface area, and brain volumes have been investigated. These T1w-derived phenotypes undergo radical changes during childhood and adolescence, while remaining relatively stable during adulthood.

1 INTRODUCTION Magnetic resonance spectroscopy (MRS) can non-invasively quantify the levels of metabolites in the central neural system by measuring different resonance frequencies of the proton hydrogen (1H) embedded in them (Oz et al., 2014; Wilson et al., 2019). In typical applications, a 5-min acquisition time can provide a good-quality dataset, where the spectra of a single voxel can be obtained (Wilson et al., 2019).
