Estrogenic regulation of hippocampal inhibitory system across lifespan

open access: yesJournal of Neuroendocrinology, EarlyView.
Abstract Estrogens produced in peripheral tissues and locally in the brain are potent neuromodulators. The function of the hippocampus, a brain region essential for episodic memory and spatial navigation, relies on the activity of ensembles of excitatory neurons whose activity is temporally and spatially coordinated by a wide diversity of inhibitory ...

MRI‐based surrogates of brain clearance in narcolepsy type 1

open access: yesJournal of Sleep Research, EarlyView.
Summary Brain clearance involves the drainage of waste molecules from the brain, a process that is suggested to be amplified during sleep. Recently proposed MRI‐based methods attempt to approximate human brain clearance with surrogate measures. The current study aimed to explore whether two brain clearance surrogates are altered in narcolepsy.

The Space–Time Organisation of Sleep Slow Oscillations as Potential Biomarker for Hypersomnolence

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Research suggests that the spatial profile of slow wave activity (SWA) could be altered in hypersomnolence. Slow oscillations (SOs; 0.5–1.5 Hz), single waveform events contributing to SWA, can be labelled as Global, Frontal, or Local depending on their presentation on the scalp.

Neurogenomic landscape associated with status‐dependent cooperative behaviour

open access: yesMolecular Ecology, EarlyView.
Abstract The neurogenomic mechanisms mediating male–male reproductive cooperative behaviours remain unknown. We leveraged extensive transcriptomic and behavioural data on a neotropical bird species (Pipra filicauda) that performs cooperative courtship displays to understand these mechanisms.

The human colon: Evidence for degenerative changes during aging and the physiological consequences

open access: yesNeurogastroenterology &Motility, EarlyView.
Reduced nociceptor innervation can explain diminished abdominal pain among the elderly. Degenerative changes occur within the colon wall, especially ascending colon. Mechanisms may include senescence‐like activity and inflammaging. Constipation is more likely to occur during age‐related challenges affecting functions of the bowel that now have reduced ...
