M64. Real Time fMRI Feedback Targeting Default Mode Network (DMN) Reduces Auditory Hallucinations

Default Mode Network (DMN) Activity during Olfactory Processing

Introduction: The dynamics of resting state networks during active and passive task performance has received increased attention in recent times [1, 2]. Several studies have reported modulations in the default mode network (DMN) (or deactivations) during the performance of sensoryand cognitivefMRI tasks [1, 2, 3]. However, no study has investigated such modulations in relation to olfaction. Usi...

Real-Time Output Feedback Neurolinearization

 An adaptive input-output linearization method for general nonlinear systems is developed without using states of the system. Another key feature of this structure is the fact that, it does not need model of the system. In this scheme, neurolinearizer has few weights, so it is practical in adaptive situations.  Online training of neuroline...

Roles of default-mode network and supplementary motor area in human vigilance performance: evidence from real-time fMRI.

We used real-time functional magnetic resonance imaging (fMRI) to determine which regions of the human brain have a role in vigilance as measured by reaction time (RT) to variably timed stimuli. We first identified brain regions where activation before stimulus presentation predicted RT. Slower RT was preceded by greater activation in the default-mode network, including lateral parietal, precun...

The Significance of the Default Mode Network (DMN) in Neurological and Neuropsychiatric Disorders: A Review

The relationship of cortical structure and specific neuronal circuitry to global brain function, particularly its perturbations related to the development and progression of neuropathology, is an area of great interest in neurobehavioral science. Disruption of these neural networks can be associated with a wide range of neurological and neuropsychiatric disorders. Herein we review activity of t...
