What is QEEG?
QEEG (Quantitative Electroencephalogram) or Brain Mapping is a procedure that records
neural activities of the brain from at least 19 locations on the scalp. Very similar
to the Electrocadiogram or EKG which measures activities of the heart at the surface
of the chest, QEEG measures activities of neurons or brain cells at the surface of
the scalp simultaneously from at least 19 locations. It is important that the activities
are measured simultaneously or at the same time, so that we can understand how the
brain work as a whole. Studies showed that a minimum of 19 locations is required
to map our brain function. More is better but any thing less than 19 locations will
not provide sufficient resolution.
QEEG is Safe and non-invasive:
Like neurofeedback, QEEG is a safe and non-invasive assessment. Sensors are first
placed on the surface of a person's scalp. Then, EEG activity is measured under different
states and tasks that a person frequently encounters, such as eyes closed, eyes open,
reading, writing, listening, doing arithmetic and etc. We only measure what the brain
sends out, nothing is discharged into the brain.
A Brain Imaging Technique
The QEEG assessment can be considered as a brain imaging technique. It tells us what
the brain is doing. Our brain is so well protected by the skull such that we cannot
see or feel what the brain is doing. A QEEG assessment will provide an invaluable
picture of the state of our brain and how we are utilizing it. From the QEEG, we
How one is regulating sensory information
Areas that are over-active
Areas that are fatigue or exhausted
Areas that shut-down while on task
Which regions of the brain are utilized for a task
How each brain regions are working together ... And more
At Spectrum Learning, we routinely do a QEEG assessment for our clients. With this
information, we can then design a specific brain exercise program using neurofeedback.
This leads to a more effective brain exercise. For example, those regions that are
exhausted, we can train for recovery. For those areas that are weak, we can train
to increase the neural activities. This tends to produce faster results.
