Note on Neurofeedback of Patients of Insomnia

Abstract

FMRI (functional magnetic resonance imaging) is meant for measuring the blood oxygenation level based signal in the brain. It is a quantity that comes from various physiological and biophysical sources and denotes to neural activity a vascular coupling. FMRI has particular preference over other neuroimaging non-invasive methods like electroencephalographic recordings (EEG). rtfMRI, (real time fmri) is a process that adopts functional counsel from a MRI scanner where the fMRI keep runs to data acquisition. Currently, rtfMRI is applied to intraoperative surgical guidance, brain–computer interfaces , and neurofeedback. Insomnia is a disorder in sleep that constantly affects several crores of people worldwide. People with insomnia finds it hard to go to asleep or remain asleep. Using rest-state functional connectivity depending on variations in certain regions of interest in brain one can examine connectivity alterations on patients of insomnia.. In this paper, we have reported on the findings of Huan Zhang et al’s approach concerning rt-fMRI (real-time functional magnetic resonance neurofeedback) therapy for training for patients of insomnia.
