Interpreting your brain activity via an EEG.

What is an EEG?

An electroencephalogram (EEG) measures electrical patterns of the brain. These patterns reflect cortical activity and are commonly known as brainwaves.

How we use it
The science behind it

We use quantitative EEG (q-EEG), also referred to as brain mapping, and an electrocardiogram (EKG) which maps the electrical activity of the heart, to further understand an individual’s brain activity.

Typical EEG Findings for Different
Brain States

Brain activity varies a great deal from individual to individual. People with neurological issues may have significant EEG rhythm variations that result in excessive or reduced brain metabolism.


These deficits may correspond to disruptions in cognition and sensory processing, anxiety and development issues impairing communication and interaction.


This may correspond to general restlessness, difficulty focusing and attentional problems.

Focal Excess

This activity may correspond to interruptions of function in structures that have been traumatically damaged.

Frontal Lobe Excess

This activity may correspond with lack of motivation, emotional numbness and depressive tendencies.


No notable excesses or deficits.

Scientific literature reports that different kinds of EEGs correspond to different neurological illnesses

Composition of Brain Oscillations in Ongoing EEG During Major Depression Disorder, Fingelkurts et al, 2006

The study found that major depression affects major brain activity and the findings provide insight on the relationship between major depressive disorder and cortical oscillatory activity.

EEG Changes Associated with Autistic Spectrum Disorders, Boutros et al, 2015

The bulk of the evidence supports significant connectivity disturbances in ASD that are possibly widespread with two specific aspects: over-connectivity in the local networks and under-connectivity in the long-distance networks.

Electroencephalogram abnormalities in panic disorder patients: a study of symptom characteristics and pathology; Hayashi et al, 2010

Since the 1980s, a high EEG abnormality rate has been reported for patients with panic disorder. However, how the EEG abnormalities of panic disorder patients are related to the clinical features and pathology of these patients has yet to be clarified. The study investigated whether or not EEG abnormalities are related to the 13 symptoms in the DSM-IV criteria for a diagnosis of panic attacks.

The Quantitative Electroencephalogram and the Low-Resolution Electrical Tomographic Analysis in Posttraumatic Stress Disorder, Todder et al, 2012

The findings support existing research data obtained via other imaging technologies, which demonstrated structural alterations in the right temporal and frontal areas in PTSD. These results indicate that combining quantitative EEG (QEEG) and the LORETA method, among other methods, may improve the neuroanatomical resolution of EEG data analysis.

EEG Alpha Rhythm Frequency and Intelligence in Normal Adults, Anokhin & Vogel, 1996

The electroencephalogram (EEG) reflects stable individual differences in brain function and therefore can be a powerful instrument for exploring the biological basis of intelligence.
