Psychophysiological studies and MRI neuro-imaging findings provide evidence that heart rate variability (HRV) which is in control of our emotions affects our brain cognitive centers. It has been shown that coherent heart-brain interaction can change the pattern of the afferent cardiac input that is sent to the brain. For this purpose, the Institute of HeartMath (IHM) has proposed a kind of biof...

A robust body of research documents that there are biological predispositions that often exist for depression, anxiety, and obsessive–compulsive disorder. However, new research has shown that medication is only mildly more effective than placebo in the treatment of these problems. In treating these conditions, neurofeedback (EEG biofeedback) may offer an alternative to invasive treatments such ...

The signature wounds of the Iraq War are traumatic brain injury and post traumatic stress disorder (PSTD). Due to an emergent need to address the symptoms of these wounds in returning Marines and navy corpsmen, a memorandum of understanding between the U.S. Marine Corps and East Carolina University’s Psychophysiology Lab and Biofeedback Clinic was signed and training services were begun in Febr...

This study investigated the level of self-regulation of the somatomotor cortices (SMCs) attained by an extended functional magnetic resonance imaging (fMRI) neurofeedback training. Sixteen healthy subjects performed 12 real-time functional magnetic resonance imaging neurofeedback training sessions within 4 weeks, involving motor imagery of the dominant right as well as the non-dominant left han...

Working memory (WM) is a part of human memory, the ability to maintain and manipulate information. WM performance is impaired in some neurological and psychiatric disorders such as schizophrenia and ADHD. Neurofeedback training is a self-regulation method which can be used to improve WM performance by changing related EEG parameters. In this paper we used neurofeedback training to improve WM pe...

When people learn foreign languages, they find it difficult to perceive speech sounds that are nonexistent in their native language, and extensive training is consequently necessary. Our previous studies have shown that by using neurofeedback based on the mismatch negativity event-related brain potential, participants could unconsciously achieve learning in the auditory discrimination of pure t...

BACKGROUND Neurofeedback has been applied effectively in various areas, especially in the treatment of children with attention-deficit/hyperactivity disorder (ADHD). This study protocol is designed to investigate the effect of slow cortical potential (SCP) feedback and a new form of neurofeedback using near-infrared spectroscopy (NIRS) on symptomatology and neurophysiological parameters in an a...

Neurofeedback (NF) is being successfully applied, among others, in children with attention deficit/hyperactivity disorder (ADHD) and as a peak performance training in healthy subjects. However, the neuronal mechanisms mediating a successful NF training have not yet been sufficiently uncovered for both theta/beta (T/B), and slow cortical potential (SCP) training, two protocols established in NF ...
