This is three sets of data from the same underlying EEG, all with varying coherence results, and with the weighted average showing the alpha hypercoherent pattern with better fidelity than any other for this data.

Drug exposure and EEG/qEEG findings
A technical guide by Jay Gunkelman, QEEG-D
General comments:
There is a generally reciprocal effect between alpha and beta, as brain stem stimulation desynchronizes the alpha generators, beta is seen. During states of under-arousal, this relationship is not seen, as when the subject is alerted, when both alpha and beta increase.
The point is that the arousal level [...]
Concern Regarding the Mitsar Amplifier
The concern regarding the Mitsar amplifier expressed with so much vigor by those with competing interests has met the reality test of actual recorded data. The concern expressed was over a theoretical time skewing error due to the data sampling of an older version of the Mitsar amplifier.
I suggested at the [...]
Brain Mechanisms Meeting – February 11th to the 13th, 2010
Brain Mechanisms Meeting From February 11th to the 13th, 2010, professionals of Neuroscience are invited to attend the most important international meeting of the year, that is going to take place in Madrid, Spain. See full PDF in English or Spanish
It’ll be the first Neuroscience Multidisciplinary Meeting hosted by the Brainmech Foundation in Spain [...]
Neurofeedback and the Brain
Neurofeedback is an emerging neuroscience-based clinical application, and understanding the underlying principles of neurofeedback allows the therapist to provide referrals or treatment, and provides clients with a framework for understanding the process. The brain’s electrical patterns are a form of behavior, modifiable through “operant conditioning,” with the excessive brain frequencies reduced, and those with a [...]
Thalamic Involvement in the Generation of the Alpha Rhythms
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 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 [...]
Dementia and Alzheimer’s Disease: LORETA findings
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 [...]
A discussion on LORETA software use and licensing.
April 30, 2009
Leslie Sherlin, PhD
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 [...]
