How Smart Is It to Go to Bed with the Phone? The Impact of Short-Wavelength Light and Affective States on Sleep and Circadian Rhythms

by Admin1 | Oct 28, 2021

Previously, we presented our preliminary results (N = 14) investigating the effects of short-wavelength light from a smartphone during the evening on sleep and circadian rhythms (Höhn et al., 2021). Here, we now demonstrate our full sample (N = 33 men), where...

The actigraphic documentation of circadian sleep-wake rhythm dysregulation in Myotonic Dystrophy Type 1

by Admin1 | Oct 15, 2021

Study Objectives The present study aimed at identifying the sleep-wake rhythm in patients with myotonic dystrophy type 1 (DM1) compared to healthy controls. Methods Patients with genetic diagnosis of DM1 and healthy controls underwent a 7-day actigraphic recording and...

Diurnal variations of resting-state fMRI data: A graph-based analysis

by Admin1 | Oct 12, 2021

Circadian rhythms synchronize a variety of physiological processes ranging from neural activity and hormone secretion to sleep cycles and feeding habits. Despite significant diurnal variation, time-of-day (TOD) is rarely recorded or analyzed in human brain research....

Event-related desynchronization in motor imagery with EEG neurofeedback in the context of declarative interference and sleep

by Admin1 | Oct 12, 2021

Motor imagery (MI) in combination with neurofeedback (NF) is a promising supplement to facilitate the acquisition of motor abilities and the recovery of impaired motor abilities following brain injuries. However, the ability to control MI NF is subject to a wide range...

Effects of the selective orexin-2 receptor antagonist JNJ-48816274 on sleep initiated in the circadian wake maintenance zone: a randomised trial

by Admin1 | Oct 9, 2021

The effects of orexinergic peptides are diverse and are mediated by orexin-1 and orexin-2 receptors. Antagonists that target both receptors have been shown to promote sleep initiation and maintenance. Here, we investigated the role of the orexin-2 receptor in sleep...
