Resting-State Networks in Schizophrenia

Current Topics in Medicinal Chemistry, 2012
Schizophrenia has been conceptualized as a disorder of altered brain connectivity (i.e. dysconnectivity). Until relatively recently, it was not feasible to test dysconnectivity hypotheses of schizophrenia in vivo. Resting-state functional magnetic resonance imaging (fMRI) is a powerful tool for mapping functional networks of the brain, such as the ...

Is Rest Really Rest? Resting-State Functional Connectivity During Rest and Motor Task Paradigms

Brain Connectivity, 2018
Numerous studies have identified several large-scale networks within the brain of healthy individuals, some of which have been attributed to ongoing mental activity during the wakeful resting state. While engaged during specific resting-state functional magnetic resonance imaging (fMRI) paradigms, it remains unclear as to whether traditional block ...

Resting-State-fMRT

2013
Das folgende Kapitel soll eine Einfuhrung in die funktionelle MRT wahrend des Ruhezustandes des Gehirns (»resting state«) geben, d. h. von bildgebenden fMRT-Untersuchungen, die in Abwesenheit externer Reize oder ohne explizite Aufgaben durchgefuhrt und daher auch bei Kindern und Patienten angewendet werden konnen.

Caffeine effects on resting-state arousal

Clinical Neurophysiology, 2005
This study examined the use of caffeine to manipulate arousal level without the confounds associated with task-related activation. From previous work in our laboratory, an increase in skin conductance level (SCL) and EEG alpha frequency, together with a global decrease in alpha power, were used as markers of arousal increase, and we sought to identify ...

Presurgical Resting-State fMRI

2014
Purpose: Task-based fMRI has traditionally been used to locate eloquent regions of the brain that are relevant to specific cognitive tasks. These locations have, in turn, been used successfully to inform surgical planning. Resting-state functional MRI (fMRI) uses alternative methods to find networks, but does not require any task performance by a ...
