Neurofeedback
Neurofeedback (NFB), also called neurotherapy, is a type of biofeedback that presents real-time feedback from brain activity in order to reinforce healthy brain function through operant conditioning. Typically, electrical activity from the brain is collected via sensors placed on the scalp using electroencephalography (EEG), with feedback presented using video displays or sound. The effectiveness of neurofeedback is disputed. While studies and reviews have often found neurofeedback treatment to be beneficial for the patient, it has yet to be shown these effects are directly caused by the neurofeedback technique applied. Placebo-controlled trials have often found the control group to show the same level of improvement as the group receiving actual neurofeedback treatment, which suggests these improvements may be caused by secondary effects instead. Despite this controversy and never having gaining prominence in the medical mainstream, it has been practiced for over four decades. NFB ...

Biofeedback
Biofeedback is the process of gaining greater awareness of many physiology, physiological functions of one's own body by using Electronics, electronic or other instruments, and with a goal of being able to Manipulation (psychology), manipulate the body's systems at will. Humans conduct biofeedback naturally all the time, at varied levels of consciousness and intentionality. Biofeedback and the biofeedback loop can also be thought of as Emotional self-regulation, self-regulation. Some of the processes that can be controlled include Electroencephalography, brainwaves, muscle tone, skin conductance, heart rate and pain perception. Biofeedback may be used to improve health, performance, and the physiological changes that often occur in conjunction with changes to thoughts, emotions, and behavior. Recently, technologies have provided assistance with intentional biofeedback. Eventually, these changes may be maintained without the use of extra equipment, for no equipment is necessaril ...

Hemoencephalography
Hemoencephalography (HEG) is a neurofeedback technique in the field of neurotherapy. Neurofeedback, a specific form of biofeedback, is based on the idea that human beings can consciously alter their brain function through training sessions in which they attempt to change the signal generated by their brain and measured via a neurological feedback mechanism. On completion of the process, participants increase cerebral blood flow to a specified region of the brain, consequently increasing brain activity and performance on tasks involving the specific region of the brain.Tinius, T. (2004). New Developments in Blood Flow Hemoencephalography. Hawthorne Press. Overview Both approaches to hemoencephalography, near infrared and passive infrared, are indirect measures of neural activity based on neurovascular coupling. Neurovascular coupling is the mechanism by which cerebral blood flow is matched to metabolic activity. When a region of the cortex is used in a specific cognitive task, neu ...

Alpha Rhythm
Alpha waves, or the alpha rhythm, are neural oscillations in the frequency range of 8–12 Hz likely originating from the synchronous and coherent (in phase or constructive) electrical activity of thalamic pacemaker cells in humans. Historically, they are also called "Berger's waves" after Hans Berger, who first described them when he invented the EEG in 1924. Alpha waves are one type of brain waves detected by electrophysiological and closely related methods, such as by electroencephalography (EEG) or magnetoencephalography (MEG), and can be quantified using quantitative electroencephalography (qEEG). They can be predominantly recorded from the occipital lobes during wakeful relaxation with closed eyes and were the earliest brain rhythm recorded in humans. Alpha waves are reduced with open eyes and sleep, while they are enhanced during drowsiness. Historically, they were thought to represent the activity of the visual cortex in an idle state. More recent papers have argued t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Barbara Brown (scientist)
Barbara B. Brown (1921–1999) was a research psychologist who popularized biofeedback and neurofeedback in the 1970s. ''Biofeedback Magazine,'' a publication of the Association for Applied Psychophysiology and Biofeedback (AAPB), noted that she was "among the first and most successful to make the public aware of the power and potential of biofeedback." Brown earned her Ph.D. in Pharmacology from the University of Cincinnati College of Medicine in 1950. She went from a technician at the William S. Merrell division of pharmaceutical company Richardson-Merrell to heading Merell's Department of Pharmacology. From there, she went to Riker Laboratories, then to Psychopharmacology Research Laboratories. Brown later became an Associate Clinical Professor of Pharmacology at the University of California, Los Angeles Center for Health Sciences and at the University of California, Irvine. She also lectured in the Department of Psychiatry at University of California, Los Angeles. Brow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electroencephalography
Electroencephalography (EEG) is a method to record an electrogram of the spontaneous electrical activity of the brain. The biosignals detected by EEG have been shown to represent the postsynaptic potentials of pyramidal neurons in the neocortex and allocortex. It is typically non-invasive, with the EEG electrodes placed along the scalp (commonly called "scalp EEG") using the International 10-20 system, or variations of it. Electrocorticography, involving surgical placement of electrodes, is sometimes called " intracranial EEG". Clinical interpretation of EEG recordings is most often performed by visual inspection of the tracing or quantitative EEG analysis. Voltage fluctuations measured by the EEG bioamplifier and electrodes allow the evaluation of normal brain activity. As the electrical activity monitored by EEG originates in neurons in the underlying brain tissue, the recordings made by the electrodes on the surface of the scalp vary in accordance with their orientation and ...

Quantitative Electroencephalography
Quantitative electroencephalography (qEEG or QEEG) is a field concerned with the numerical analysis of electroencephalography (EEG) data and associated behavioral correlates. Details Techniques used in digital signal analysis are extended to the analysis of electroencephalography (EEG). These include wavelet analysis and Fourier analysis, with new focus on shared activity between rhythms including phase synchrony (coherence, phase lag) and magnitude synchrony (comodulation/correlation, and asymmetry). The analog signal comprises a microvoltage time series of the EEG, sampled digitally and sampling rates adequate to over-sample the signal (using the Nyquist principle of exceeding twice the highest frequency being detected). Modern EEG amplifiers use adequate sampling to resolve the EEG across the traditional medical band from DC to 70 or 100 Hz, using sample rates of 250/256, 500/512, to over 1000 samples per second, depending on the intended application. QEEG can be per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brainwave Synchronization
Brainwave entrainment, also referred to as brainwave synchronization or neural entrainment, refers to the observation that brainwaves (large-scale electrical oscillations in the brain) will naturally synchronize to the rhythm of periodic external stimuli, such as flickering lights, speech, music, or tactile stimuli. As different conscious states can be associated with different dominant brainwave frequencies, it is hypothesized that brainwave entrainment might induce a desired state. Researchers have found, for instance, that acoustic entrainment of delta waves in slow wave sleep had the functional effect of improving memory in healthy subjects. Neural oscillation Neural oscillations are rhythmic or repetitive electrochemical activity in the brain and central nervous system. Such oscillations can be characterized by their frequency, amplitude and phase. Neural tissue can generate oscillatory activity driven by mechanisms within individual neurons, as well as by interactions bet ...
