This is the first of a few posts with a variety of ways the EEG can show an epileptogenic process. The morphology of the underlying process are quite dramatically varied.
The two images below show the referential and sequential montage display of an active right temporal-parietal spike and slow wave focus, [...]

How EEG can Show an Epileptogenic Process
Epilepsy and EEG
Epilepsy and EEG have been inextricably linked since the 1930s, when Frederick and Erna Gibbs discovered that epileptic events were visible in the EEG. The evolution of other medical imaging in the 1970s and 1980s provided a better way to localize tumors, and the clinical use tapered off in areas other [...]
The Art of Aging: Limitless Potential of the Brain
This is an excellent video talking about how seniors can help keep their brains young.
How can we live a fuller and healthier lifestyle as we get older? Perhaps keeping our body and brain engaged can help. That seems to be the case in Japan where the number of centegenarians is greater than 20,000.
THE ART [...]
Three Sets of Data from the Same EEG
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.
AAPB 41st Annual Meeting : Personalized Medicine in the Age of Technology: Psychophysiology & Health
AAPB is traveling to San Diego, California for its 41st Annual Meeting. Mark your calendars for March 24-27, 2010 to attend this gathering of experts in biofeedback, neurofeedback, and applied psychophysiology. You won’t want to miss this educational event and the networking opportunities available!
We are honored to welcome several high-profile speakers, including:
Personalized Medicine in the [...]
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 [...]
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 [...]
Brain Power

This video was recently shown again on CBS 60 Minutes. It is a great video talking about using brain controlled interfaces.
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 [...]
