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 out what does. Now, based on the final results of a nationwide study led by UCLA, clinician ...

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 an inexpensive alternati ...

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 high school sports or ...

Brain imaging and analysis continues to evolve and provide us with more information upon which to 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 cellular architectures he observed. The Brodmann area information has been employed for more tha ...

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 lobe disturb ...

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 of age with an peak onset arou ...

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 their implications for neurofeedback mostly draw from the writings of Johnston, Gunkel ...

In Part 1 of this series, I provided an introduction to and overview of the candidate EEG phenotypes as proposed by Johnstone, Gunkelman, & Lunt (2005). Readers may want to first view Part 1 to better understand the current discussion. Part 2 provides a detailed description of 5 of the 11 candidate EEG phenotypes along with their implications for neurofeedback treatment planning as described by Johnston, Gu ...

Researchers* recently proposed the existence of numerous EEG phenotypes. EEG phenotypes were derived through Johnston, Gunkelman, & Lunt's (2005) extensive clinical experience and the observation that similar EEG patterns recur in persons with different psychological disorders. EEG phenotypes are a useful method of EEG pattern categorization that requires visual inspection the raw EEG, and often, the quanti ...

Many neurofeedback clinicians and researchers are already aware of this latest free resource to be added to The Behavioral Medicine Report. However, I want to alert the general public, students, and other interested persons to this excellent document from The International Society of Neurofeedback and Research (ISNR): The Comprehensive Neurofeedback Bibliography. Check the end of this article for a link to ...
