Assessing interactions in the brain with exact low-resolution electromagnetic tomography
TLDR
A solution to this inverse problem that attains exact localization: exact low-resolution brain electromagnetic tomography (eLORETA) is reported, which yields high time-resolution intracranial signals that can be used for assessing functional dynamic connectivity in the brain.
Cognitive dysfunction in psychiatric disorders: characteristics, causes and the quest for improved therapy
TLDR
This article critically discusses the challenges and opportunities for improving cognition in individuals suffering from psychiatric disorders, highlighting the needs to characterize the cellular and cerebral circuits underpinning cognitive function and identify more effective treatments.
Sleep spindles and their significance for declarative memory consolidation.
TLDR
Results indicate that increased sleep stage 2 spindle activity is related to an increase in recall performance and, thus, may reflect memory consolidation in stage 2 sleep.
An E-Health Solution for Automatic Sleep Classification according to Rechtschaffen and Kales: Validation Study of the Somnolyzer 24 × 7 Utilizing the Siesta Database
TLDR
The development and optimization of an automatic classification system that is based on one central EEG channel, two EOG channels and one chin EMG channel and proved the high reliability and validity of the Somnolyzer 24 × 7 and demonstrated its applicability in clinical routine and sleep studies.
Topographic distribution of sleep spindles in young healthy subjects
The application of an automatic sleep spindle detection procedure allowed the documentation of the topographic distribution of spindle characteristics, such as number, amplitude, frequency and
Sleep spindle‐related activity in the human EEG and its relation to general cognitive and learning abilities
TLDR
It is suggested that besides being involved in shaping neuronal networks after learning, sleep spindles do reflect important aspects of efficient cortical‐subcortical connectivity, and are thereby linked to cognitive‐ and memory‐related abilities alike.
Interrater reliability for sleep scoring according to the Rechtschaffen & Kales and the new AASM standard
TLDR
The results of this study underline that the modification of the scoring rules improve IRR as a result of the integration of occipital, central and frontal leads, but decline IRR on the other hand specifically for N2, due to the new rule that cortical arousals with or without concurrent increase in submental electromyogram are critical events for the end of N2.
Depression and quality of life in multiple sclerosis
TLDR
Clinical studies, which seek to register the increasingly important evaluation criterion of health‐related quality of life in MS, should consider the prevalence of depressive disorders and the decisive effect of depression on the self‐assessed quality oflife of affected patients.
