Nicotinic receptor modulation of the default mode network
Psychopharmacology, 2020Previous neuroimaging studies of cognition involving nicotinic acetylcholine receptor (nAChR) agonist administration have repeatedly found enhanced task-induced deactivation of regions of the default mode network (DMN), a group of brain systems that is more active at rest and mediates task-independent thought processes.

Den Gedanken freien Lauf zu lassen, liefert neue Einblicke in die Gehirnfunktion. Die Ausenwelt auszuschalten und in die geistige Welt der Tagtraume und der Fantasie einzutreten, aktiviert eine Gruppe von Hirnregionen, die als Default Mode Network (Bewusstseins- oder Ruhezustandsnetz) bezeichnet wird und wahrend anspruchsvoller Aufgaben abgeschaltet ...

Insomnia Disorder and Brain’s Default-Mode Network
Current Neurology and Neuroscience Reports, 2018Insomnia disorder (ID) is a prevalent sleep disorder that significantly compromises the physical and mental health of individuals. This article reviews novel approaches in the study of brain networks and impaired function in ID through the application of modern neuroimaging techniques such as functional magnetic resonance imaging (fMRI).The default ...

Boredom, sustained attention and the default mode network
Experimental Brain Research, 2016Boredom is a ubiquitous human experience that can best be described as an inability to engage with one's environment despite the motivation to do so. Boredom is perceived as a negative experience and demonstrates strong associations with other negatively valenced states including depression and aggression. Although boredom has been shown to be elevated

Dreaming and the Default Mode Network
Contemporary Psychoanalysis, 2013AbstractThis article makes a brief contribution to the ongoing dialogue on dreams between neuroscience and psychoanalysis by linking several converging lines of evidence. Recent evidence indicates that the default mode network (DMN), a highly interconnected set of “hubs” in the brain, is active during sleep. In addition, activity in the DMN is strongly

Effects of Semax on the Default Mode Network of the Brain
Bulletin of Experimental Biology and Medicine, 2018The effects of nootropic drug Semax on the neuronal network of the brain were studied by the resting state functional magnetic-resonance imaging (resting state fMRI). The study was carried out on two groups of healthy volunteers (11 men and 13 women aged 43.9±9.5 years). Resting state fMRI was carried out 3 times: directly before and 5 and 20 min after

Cognition, emotion, and the default mode network
Brain and CognitionThe Default Mode Network (DMN) is increasingly recognized as a key hub where cognitive and emotional processes converge, particularly through its role in integrating episodic memory and emotional experiences. The current mini-review highlights three distinct patterns of brain activity within the DMN associated with emotional processing.
