Quantitative Electroencephalography (qEEG): Information & Discussion
From Issue 3 of Autism Science Digest: The Journal of Autism One.
By: James Neubrander MD, Michael Liden PhD, Jay Gunkleman QEEGD, and Cynthia Kerson PhD.
QEEG-guided neurofeedback is based on normalizing dysregulated brain regions that relate to specific clinical presentation. With ASD, this means that the approach is specific to each individual’s QEEG subtype patterns and [...]
Consciousness: An Emergent Property Of Mind-Brain Interaction – presented by Jay Gunkelman
A model of consciousness will be illustrated with physiological data from EEG and Event related potentials. Using millisecond level time resolution, a working model of the interaction between the mind and the brain will be constructed.
The Slow Cortical Potentials generated by Glial activity and [...]
Alpha… it’s not a simple idling rhythm… let’s look at alpha generators:
The thalamic involvement in the generation of the alpha rhythm is being under-valued when looking at the LORETA images of alpha current source generators. The alpha power may come from the sources that LORETA identifies, but the thalamus is intimately involved in alpha [...]
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 [...]
Life offers us many teachers, and we generally only learn a small sliver of what they have to offer from the breadth and depth of their experience.
One such teacher was E. Roy John, who most knew as a brain researcher, though he had so much more to offer… did you know he was “blacklisted” [...]

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 [...]
I often get questions about Alzheimer’s Disease (AD) and the EEG.
Whenever a client presents with the question of dementia, all other forms of
dementia need to be ruled out before you are left with the diagnosis of AD.
There are many EEG signatures of various forms of dementia, all of which are
helpful in evaluating a client’s presentation [...]
