Brain mapping, also known as quantitative electroencephalogram (QEEG) is the assessment tool we use to determine the right neurofeedback protocols. The EEG recording is then interpreted with the NeuroGuide statistical database and LORETA (low resolution electromagnetic tomographic analysis) current source density algorithms.
The CNSVS (Central Nervous System Vital Signs) assessment augments the QEEG assessment to determine specific brain responses and behaviors to a battery of brain challenges.
The IVA (Integrated Auditory and Visual Continuous Performance Test) may also be used to augment the QEEG assessment to compare the brain's response to visual and auditory cues.
A Psychophysiological Stress Profile (PPSP) is used to determine how you respond to stressful input and is used to determine the right biofeedback protocols.
Brain Mapping (Quantitative Electroencephalogram (QEEG)
Brain mapping is the oft-used term for the quantitative electroencephalograph or QEEG. This diagnostic tool records the brain's electrical profile under different tasks. These tasks may include eyes open, eyes closed, and reading and math challenges. A QEEG is important because while some people have the same behavioral issues, their brain wave profiles can differ dramatically. It is necessary to have a brain map for patients who have had a stroke, have seizures and/or who have had a brain injury or other organic issue. A brain map is also important when learning, memory and cognitive syndromes are present.
The test usually takes about 1 to 1 1/2 hours. A spandex cap is placed over the head and is fitted to match up with the common sites used by neurofeedback therapists. The map is then interpreted to discern the individual's electrical profile, allowing a more comprehensive clinical approach to the neurotherapy.
There are many ways of interpreting a QEEG. Examples of brain maps are shown below. For a discussion about what would be the best interpretation, please contact Cynthia Kerson, PhD at (415) 485-1342 or email. Each of these maps offers a different approach to interpretation of the brain's electrical information.
CNSVS (Central Nervous System Vital Signs)
The CNSVS is a computer tool to assess brain function on many levels including memory, cognitive flexibility, psychomotor speed and other neurocognitive functions. The test can take from 25 to 60 minutes.
IVA (Integrated Auditory and Visual Continuous Performance Test)
The IVA takes about 20 minutes to complete. It's a very simple continuous performance test that looks at differences in auditory and visual function.
Psychophysiological Stress Profile (PPSP)
The PPSP is used to measure all the peripheral measures and brain waves under stress and relax conditions. We use this test to determine patterns of disregulation and design biofeedback training based upon the client's specific needs.
