Boosting Slow Oscillations during Sleep

Link – Boosting Slow Oscillations during Sleep to Improve Memory Function in Elderly People: A Review of the Literature. Abstract Sleep represents a crucial time window for the consolidation of memory traces. In this view, some brain rhythms play a pivotal role, first of all the sleep slow waves. In particular, the neocortical slow oscillations […]

Closed-Loop Feedback Techniques in Sleep Studies

Link – A Systematic Review of Closed-Loop Feedback Techniques in Sleep Studies-Related Issues and Future Directions. Abstract Advances in computer processing technology have enabled researchers to analyze real-time brain activity and build real-time closed-loop paradigms. In many fields, the effectiveness of these closed-loop protocols has proven to be better than that of the simple open-loop […]

Targeting Arousal and Sleep through Noninvasive Brain Stimulation

Link – Targeting Arousal and Sleep through Noninvasive Brain Stimulation to Improve Mental Health. Abstract Arousal and sleep represent fundamental physiological domains, and alterations in the form of insomnia (difficulty falling or staying asleep) or hypersomnia (increased propensity for falling asleep or increased sleep duration) are prevalent clinical problems. Current first-line treatments include psychotherapy and […]

Sleep staging using Plausibility Score

Link – Sleep staging using Plausibility Score: A novel feature selection method based on metric learning. Abstract As an effective method, feature selection can reduce computational complexity and improve classification performance. A number of criteria exist for feature selection using labeled data, unlabeled data and pairwise constraints, most of which are based on the Euclidean […]

tDCS Decreases Total Sleep Without Disturbing Memory Consolidation.

Link – Offline Bi-Frontal Anodal Transcranial Direct Current Stimulation Decreases Total Sleep Time Without Disturbing Overnight Memory Consolidation. Abstract OBJECTIVES: A proposed replay of memory traces between the hippocampus and frontal cortical brain areas during sleep is of high relevance for overnight memory consolidation. Recently, we demonstrated that bi-frontal anodal transcranial direct current stimulation (tDCS) […]

Alterations of neural network organization during REM sleep in women

Link – Alterations of neural network organization during REM sleep in women: implication for sex differences in vulnerability to mood disorders. Abstract BACKGROUND: Sleep plays an important role in vulnerability to mood disorders. However, despite the existence of sex differences in vulnerability to mood disorders, no study has yet investigated the sex effect on sleep […]

tVNS Neuronal Activity Modulation for Insomnia.

Link – The Instant Spontaneous Neuronal Activity Modulation of Transcutaneous Auricular Vagus Nerve Stimulation on Patients With Primary Insomnia. Abstract Primary insomnia (PI) is associated with increased spontaneous neuronal activity. Transcutaneous auricular vagus nerve stimulation (taVNS) modulates brain function, and it is an effective treatment for primary insomnia. However, whether taVNS alleviates insomnia through modulating […]

Spectral sleep electroencephalographic correlates of sleep efficiency

Link – Spectral sleep electroencephalographic correlates of sleep efficiency, and discrepancies between actigraphy and self-reported measures, in older men. Abstract Discrepancies between actigraphic and self-reported sleep measures are common. Studies of people with insomnia, in whom both sleep disturbances and discrepancy are common, suggest disturbances and discrepancy reflect differences in the sleeping brain’s activity measurable using […]

The impact of sleep onset and offset on epileptiform discharges

Link – “Sleep Surge”: The impact of sleep onset and offset on epileptiform discharges in idiopathic generalized epilepsies. Abstract OBJECTIVE: To investigate the impact of sleep onset and offset on the rate of epileptiform discharges (ED) in idiopathic generalized epilepsies (IGE). METHODS: We studied the temporal distribution of EDs with mixed-effects Poisson regression modeling in […]

tDCS on sleep quality and depression

Link – The effects of repeated transcranial direct current stimulation on sleep quality and depression symptoms in patients with major depression and insomnia. Abstract IMPORTANCE: Although several strategies using transcranial direct current stimulation (tDCS) have been investigated to treat major depressive disorder (MDD), the efficacy of this treatment for patients with MDD who also have […]
