The dopaminergic system is involved in reward encoding and reinforcement learning. Dopaminergic neurons from this system in the substantia nigra/ventral tegmental area complex (SN/VTA) fire in response to unexpected reinforcing cues. The goal of this study was to investigate whether individuals can gain voluntary control of SN/VTA activity, thereby potentially enhancing dopamine release to targ...
OBJECTIVE To test a common assumption underlying the clinical use of electroencephalographic (EEG) biofeedback training (neurofeedback), that the modulation of discreet frequency bands is associated with frequency-specific effects. Specifically, the proposal was assessed that enhancement of the low beta components sensorimotor rhythm (SMR: 12-15 Hz) and beta1 (15-18 Hz) affect different aspects...
BACKGROUND Effect of neurofeedback training (NFT) on enhancement of cognitive function or amelioration of clinical symptoms is inconclusive. The trainability of brain rhythm using a neurofeedback system is uncertainty because various experimental designs are used in previous studies. The current study aimed to develop a portable wireless NFT system for alpha rhythm and to validate effect of the...
Advances in functional magnetic resonance imaging have made it possible to provide real-time feedback on brain activity. Neurofeedback has been applied to therapeutic interventions for psychiatric disorders. Since many studies have shown that most psychiatric disorders exhibit abnormal brain networks, a novel experimental paradigm named connectivity neurofeedback, which can directly modulate a ...
INTRODUCTION Biofeedback is a non-invasive method of measurement of physiological functions. Precise instruments measure the slightest changes of different body functions-which are then in a clear and understandable manner shown in the form of feedback. Person gets an insight into what is going on inside the body and thus learns to change the patterns of behavior to improve health and performan...
UNLABELLED The aim of the study was to evaluate the effectiveness of individually tailored anodal tDCs/ neurofeedback protocol for the reduction of post-operative depression after a neuroophtalmological operation of the meningioma. The neuromarkers in Quantitative EEG (QEEG) and Event-related potentials (ERPs) were utilized in the construction of protocol and evaluation. CASE DESCRIPTION A 45...
Cognitive decline is a major concern in the aging population. It is normative to experience some deterioration in cognitive abilities with advanced age such as related to memory performance, attention distraction to interference, task switching, and processing speed. However, intact cognitive functioning in old age is important for leading an independent day-to-day life. Thus, studying ways to ...
Neurofeedback cognitive training is a promising tool used to promote functions effectively and efficiently. In this study, we investigated novel functional near-infrared spectroscopy (fNIRS)-based frontoparietal connectivity (FC) neurofeedback paradigm related working memory, involving healthy adults. Compared with conventional studies, chose the network, key brain region for function modulatio...
Neurofeedback is gaining widespread attention across clinical and research domains. As our knowledge of the brain and its enigmatic mechanisms increase, so does the interest in harnessing these mechanisms to promote improved mental processes and reduce symptomatic issues. Neuroscience advances and neurofeedback will continue to evolve into a primary focus for learning, performance, and reductio...
Biofeedback and brain-computer interfacing using EEG has been receiving continuous and increasing interest. However, the limited spatial resolution of low-density scalp recordings is a roadblock to the unequivocal monitoring and targeting of neuroanatomical regions and physiological signaling. This latter aspect is pivotal to the actual efficiency of neurofeedback procedures, which are expected...
