Quantitative Electroencephalography (qEEG): Information & Discussion
A collection of great videos on the brain from Vilayanur S. Ramachandran MD, PhD
The Boy with the Incredible Brain
This is the breathtaking story of Daniel Tammet. A twenty-something with extraordinary mental abilities, Daniel is one of the world’s few savants. He can do calculations to 100 decimal places in his head, and learn [...]
Thanks to Jay Gunkelman who made a very informative post on January 27 on this forum entitled Dementia and Alzheimer’s Disease. There he described the EEG patterns that we should expect and detect when evaluating for AD or other dementias.
I’d like to just throw out there a few other findings that were discovered in a [...]

There recently has been some discussion regarding the use of low resolution brain electromagnetic tomography or LORETA, sLORETA and eLORETA. I felt compelled to make a few comments regarding this since there may be some confusion of how LORETA works and the usage of LORETA as an inverse solution specifically the [...]
In his role as the Managing Director of the Foundation for Neurofeedback and
Applied Neuroscience John Fisher recently announced the Foundation’s selection of a recipient of the Neurofeedback Foundation Award.
The Foundation gives an award to the author(s) of the publication which has
“contributed the most to furthering the field of neurofeedback” [...]
The homunculus is a spatial representation of the cortical topography of the
somato-motor strip which is dedicated to either motor or sensory function.
The two have different structural details, since there are sensory inputs
from non-motor areas.
Some people have tried to create 3D creatures which show the spatial
distortions, with the enlarged surface proportionate to the motor expression or [...]
Background:
For children with attention deficit/hyperactivity disorder (ADHD), a reduction of inattention, impulsivity and hyperactivity by neurofeedback (NF) has been reported in several studies. But so far, unspecific training effects have not been adequately controlled for and/or studies do not provide sufficient statistical power. To overcome these methodological shortcomings we evaluated the clinical efficacy of [...]

The qEEG represents the statistical manipulation of the raw EEG, so an understanding of these manipulations should precede any discussion of the qEEGs clinical indications for protocols. Without such knowledge any given finding may be misinterpreted.
Following the careful recording of the EEG, the quantitative analysis is begun with the sampling of the data to be [...]
There are many in the field of Neurotherapy who do not perform qEEGs prior to designing a clinical intervention. These people are currently practicing well within the standard of practice for this rapidly evolving field. Many within this group have standard protocols which are used on all clients, with various alterations to respond to the [...]
Diffuse slowing, with slower alpha
The ascending reticular activating system stimulates the diffuse thalamic projection system and sets the general arousal level of the brain. With an increase in the CNS arousal level, there is an increase in the mean frequency of alpha and a decreased slowing. With decreases in arousal there is a slowing of [...]
