REM sleep and muscle atonia in brainstem stroke: A quantitative polysomnographic and lesion analysis study

Lukas Heydrich, Eva Blondiaux

Important brainstem regions are involved in the regulation of rapid eye movement sleep. We hypothesized that brainstem stroke is associated with dysregulated rapid eye movement sleep and related muscle activity. We compared quantitative/qualitative polysom ...

Molecular codes and in vitro generation of hypocretin and melanin concentrating hormone neurons

Sha Li, Hasan Pezeshgi Modarres

Hypocretin/orexin (HCRT) and melanin concentrating hormone (MCH) neuropeptides are exclusively produced by the lateral hypothalamus and play important roles in sleep, metabolism, reward, and motivation. Loss of HCRT (ligands or receptors) causes the sleep ...

Cholinergic, Glutamatergic, and GABAergic Neurons of the Pedunculopontine Tegmental Nucleus Have Distinct Effects on Sleep/Wake Behavior in Mice

The pedunculopontine tegmental (PPT) nucleus has long been implicated in the regulation of cortical activity and behavioral states, including rapid eye-movement (REM) sleep. For example, electrical stimulation of the PPT region during sleep leads to rapid ...

Sleep paralysis in narcolepsy: more than just a motor dissociative phenomenon?

Francesco Manni

Sleep paralyses are viewed as pure motor phenomena featured by a dissociated state in which REM-related muscle atonia coexists with a wakefulness state of full consciousness. We present a 59-year-old man diagnosed with narcolepsy experiencing sleep paralys ...

SleepPic. Hardware Developments for a Wearable On-line Sleep and Wake Discrimination System

Dario Floreano

The design of wearable systems comes with constraints in computational and power resources. We describe the development of customized hardware for the wearable discrimination of human sleep and wake based on cardio-respiratory signals. The device was desig ...

Adaptive Sleep-Wake Discrimination for Wearable Devices

Dario Floreano

Sleep/wake classification systems that rely on phys- iological signals suffer from inter-subject differences that make accurate classification with a single, subject-independent model difficult. To overcome the limitations of inter-subject variability we s ...

Metabolic response of the cerebral cortex following gentle sleep deprivation and modafinil administration

Pierre Magistretti, Christophe Kopp

Objectives: The main energy reserve of the brain is glycogen, which is almost exclusively localized in astrocytes. We previously reported that cerebral expression of certain genes related to glycogen metabolism changed following instrumental sleep deprivat ...
