Refined Division of Sleep Stages in the Mouse Based on Distributed Deep Electrodes and Underlying Infra‐Slow Oscillation

Journal of Sleep Research, EarlyView.
ABSTRACT The mouse sleep is mostly recorded with only epidural electrodes and divided simply into NREM and REM stages. With the help of distributed intracerebral triplet electrodes, we searched for possible new electrophysiological signatures to characterise more specific sleep substages within the timeframe of seconds to tens of minutes.

Cardiovascular Responses to Natural and Auditory Evoked Slow Waves Predict Post‐Sleep Cardiac Function

Journal of Sleep Research, EarlyView.
ABSTRACT The importance of sleep as a key component of cardiovascular health has been increasingly recognized. Our previous research demonstrated that auditory‐enhanced slow waves increase cardiac function, but the underlying mechanisms behind these beneficial effects remain uncertain. In this study, we examined the influence of two types of slow waves

Noradrenergic innervation across brain regions is altered by aging and by disease progression in a mouse model of Alzheimer's disease neuropathology.

PLoS ONE
Norepinephrine plays critical roles in modulating arousal and attention, is highly dynamic in awake, behaving individuals, and has anti-inflammatory and neuroprotective actions.

Hypothalamic control of noradrenergic neurons stabilizes sleep

Hypocretin/orexin neurons are essential to stabilize sleep, but the underlying mechanisms remain elusive. We report that hypocretin neurons of the perifornical hypothalamus are highly active during rapid eye movement sleep and show state-specific ...

Sodium Oxybate Alters Sleep Architecture and Reduces Emotional Selectivity in Memory‐Related Responses

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep supports memory consolidation. Non‐rapid eye movement (NREM) and rapid eye movement (REM) sleep have been proposed to support, respectively, declarative memory consolidation and the integration of the memory affective dimension. Here, we used sodium oxybate (SXB) to modify the NREM/REM proportion during one sleep night and assessed ...

Serotonergic and noradrenergic contributions to motor cortical and spinal motoneuronal excitability in humans

Animal models indicate that motor behaviour is shaped by monoamine neuromodulators released diffusely throughout the brain and spinal cord. As an alternative to conducting a single study to explore the effects of neuromodulators on the human motor system,

All Is Relative—A Call for Considering “Physiologically Informed” Control Conditions to Improve the Mechanistic Understanding of the Effects of Physical Exercise on Cognition

Scandinavian Journal of Psychology, EarlyView.
ABSTRACT There is a growing interest in elucidating the mechanisms that drive the benefits of physical exercise on cognitive performance. A key element for a better understanding of a particular phenomenon (e.g., the mediators of the exercise‐cognition interaction) is the selection of an appropriate control condition/group as the basis for causal ...

Cannabinoid exposure during pregnancy: Cardiorespiratory effects and offspring outcomes

The Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to cannabinoids has been investigated across human and animal studies to understand its impact on physiological development. Evidence suggests that early‐life cannabinoid exposure influence multiple developmental processes, extending beyond neurodevelopmental outcomes to potentially affect placental function ...

Validation of noradrenergic memory enhancement in mice

, 2017
Emotionally arousing experiences are better remembered than non-arousing experiences. Noradrenergic activity is crucially involved in the memory enhancement of emotional arousing experiences.

Ontogenetic Noradrenergic Lesion Alters Histaminergic Activity in Adult Rats

, 2008
To determine whether noradrenergic nerves might have a modulatory role on the sensitivity or reactivity of histaminergic receptor systems in brain, behavioral effects of the respective histamine H1, H2 and H3 antagonists S(+)chlorpheniramine, cimetidine ...
