The fundamental design concept of Z score biofeedback [also known as Z-Score neurofeedback] was first introduced in 1998 (Thatcher, 1998; 1999; 2000a; 2000b). The central idea of the instantaneous Z score is the application of the mathematical Gaussian curve or ‘Bell Shaped’ curve by which probabilities can be estimated using the auto and cross-spectrum of […]
It is a long, slow slog to treat major depression. Many antidepressant medications are available, but no single biomarker or diagnostic test exists to predict which one is right for an individual. As a result, for more than half of all patients, the first drug prescribed doesn’t work, and it can take months to figure […]
University of Victoria (UVic) researcher Phil Zeman has developed a new and less expensive procedure for analyzing EEG (electroencephalogram) data that identifies the location of special brain activities. Traditionally, it is functional Magnetic Resonance Imaging (fMRI) that is used to identify which areas of the brain are active during different mental states. Zeman’s technology is […]
The Washington Post reports that the private company Brainscope received $20,000,000 to build a portable electroencephalogram (EEG) device. The company foresees an initial military application whereby an objective EEG assessment could determine the severity of a traumatic brain injury (TBI) sustained by a soldier in the field. Other non-military applications are expected, such as with […]
Brain imaging and analysis continues to evolve and provide us with more information upon which to Tag Heuer Replica Watches base our clinical decisions. Brodmann mapped the cortex according to types of neurons and their density in different cortical layers. The areas he numbered (1 to 52 in each hemisphere) followed the variations in the […]
Using QEEG technology, researchers have identified a left frontotemporal dysfunction in persons who suffer from Obsessive-Compulsive Disorder, better known as OCD*. Persons with OCD have disturbing recurrent thoughts, as well as compulsive behaviors that are difficult to suppress and provide temporary relief from anxiety. The authors note that previous research has generally suggested a frontal […]
Researchers compared the quantitative EEGs (QEEG) of 26 children with a history of stuttering to 21 age matched controls with no stuttering and may have identified important “EEG markers” of pediatric stuttering*. The authors’ epidemiological review of pediatric stuttering finds that this disorder afflicts approximately 1% of prepubertal children typically between 2 to 7 years […]
Part 1 of this series provided a basic introduction to and a list of the 11 candidate electroencephalography (EEG) phenotypes, while Part 2 covered 5 of 11 EEG phenotypes. Part 3 details the remaining 6 EEG phenotypes with some final thoughts and a wrap up of this popular series. As detailed beforehand, the phenotypes and […]
