Quantitative Electroencephalogram (qEEG)
Quantitative Electroencephalogram (qEEG)
What is Quantitative Electroencephalogram (qEEG)?
A QEEG is an assessment tool to evaluate a person's brainwaves and determine to what extent the brainwave patterns differ from normal.
Recent research shows that certain dysfunctions, such as ADHD, Schizophrenia, OCD, Depression, Specific Learning Disabilities, and others are associated with specific patterns in spontaneous and evoked electrical potentials, recorded from the head by multiple surface electrodes, and that these spontaneous potentials and especially the evoked electric potentials provide reliable brain markers of the brain function and dysfunction.
Measured data of spontaneous and evoked electrical potentials can be compared with data from a normative database, thus helping the clinicians confirm the diagnosis and establish a personalized treatment plan.
The qEEG ProcedureTo perform a QEEG mapping procedure, electrodes, also known as sensors, are typically positioned on the client’s scalp at 32 standardized locations designated by the International 10-20 System (see below). This is usually accomplished by placing a special tight lycra cap, much like a bathing cap, on the client’s head. This cap has all the electrodes already attached in their proper position and is then connected to a differential amplifier and computer with a special cable. The electrodes in the cap make contact with the skin of the scalp by means of a special gel that reduces the resistance between the electrode and the skin. The electrodes pickup the very faint electrical signals of the brain that pass through the skull and scalp and pass these on to a differential amplifier that may amplify the signal a million times or more and convert the analog signal to a digital signal before passing it on to the computer.
Understanding the numbers and graphicsThe numbers generated are Z scores which is a metric which represents how normal or abnormal a score is in comparison to the Neuroguide Database.
This Z Scores test result graphic represent either the traditional eeg bands (e.g. Delta 1-4 Hz.; Theta 4-7 Hz.; Alpha 8-12 Hz., Beta 12-25 Hz, etc.) or for specific single Hz to enable increased precision.
LEGEND of the HEADS Z SCORES GRAPHICS
- The heads use colors to represent the Z scores (Brain Activity) at 19 brain regions, with the nose on the top.
- In the color scale, grey represents scores that are normal (+/- 1 Z score).
- The dots on the head are electrode sites (e.g. the top two being prefrontal sites)
See a combination of tables and graphics of Z scores below.
ADHD Child’s EEG (8yrs old)Here is an example of three seconds of EEG recorded at 19 sites which shows the brain making normal brainwaves to start but then shifts into a dysregulated state where it makes the larger, slower brainwaves (theta). This dysregulated state is likely occurring when this ADHD child is inattentive.
When this child’s recorded brainwaves are averaged and compared to a database we find that he is making more theta activity in the frontal and prefrontal sites is greater than 97% of children his age. This information can be represented in graphs as seen below.
Same ADHD child’s EEG represented graphically:
We can see his excessive theta activity in the graph below:
Adult with Generalized Anxiety Disorder and acquired brain injuryAn overanxious woman who banged the back of her head has a different looking brainmap, showing the excessive delta and theta in the back of her head, in addition to the excessive alpha everywhere.
Adult with Obsessive Compulsive DisorderAn adult suffering with severe Obsessive Compulsive Disorder has a QEEG which shows very excessive fast wave activity, a common pattern in OCD:
Adolescent with Seizure DisorderAn adolescent with a severe seizure disorder (5x/week) had this QEEG before and after treatment:
After a course of Neurofeedback, you can see he had a much improved QEEG (and only one seizure in 3 months).
— Notice the significant reduction of Delta and Theta activity.
Facts about QEEG human brain mapping
• Brainmaps provide a great deal of additional information in a variety of tables and graphs. In addition to measures of the power of the EEG at various speeds, the Connectivity measures give information about but about how well one part of the brain is communicating with another part of the brain. This adolescent with ADHD and Obsessive Compulsive Disorder has difficulties with effective communication between various prefrontal and frontal lobe sites.
Connectivity: A measure of how the various parts of the brain communicate with each other
• The QEEG human brain mapping procedure is very relevant because it provides more information than the typical electroencephalogram (EEG). By having a QEEG done, the brain activity can be compared to a wide database of other "normal brains," helping to determine which, if any, of the brain functions is actually abnormal. QEEG can be helpful in determining whether a person's symptoms are associated with specific brain dysfunctions .This valuable information can guide treatment planning . Repeated QEEG assessments can also be used to monitor treatment progress by showing changes in brain functioning as treatment progresses and symptoms change.
EEG recording is non noninvasive and a safe painless procedure
Neurofeedback - Biofeedback
What is Neurofeedback?EEG Neurofeedback is a form of Biofeedback that uses real-time digital technology to measure electrical activity of the brain (EEG) and present this information in a form that enables the individual to perceive changes in the state of the brain and learn to modify abnormal EEG patterns.
Neurofeedback TreatmentTo rewire the brain, we make use of Neurofeedback Therapy. This treatment stimulates metabolism and blood flow, strengthens dendritic connections as well as the functioning of neurotransmitters, which accounts for improvement in the patient’s ability to carry out cognitive tasks successfully.
Treatment with EEG Neurofeedback is based on the theory that once individuals understand their brain activity and learn to manipulate their own brain waves, they will be able to continue to do so, long after the therapy has ended. Some studies have followed patients for as long as 10 years after being treated with EEG Neurofeedback and have shown no significant loss of treatment gains.
Neurofeedback Session Procedure
A non-invasive painless Procedure
- We apply electrodes to the scalp to listen in on brainwave activity.
- We process the signal by computer, and we extract information about certain key brainwave frequencies. (All brainwave frequencies are equal, but some are more equal than others....)
- We show the ebb and flow of this activity back to the person, who attempts to change the activity level. Some frequencies we wish to promote. Others we wish to diminish.
- We present this information to the person in the form of a video game. The person is effectively playing the video game with his or her brain. Eventually the brainwave activity is "shaped" toward more desirable, more regulated performance. The frequencies we target, and the specific locations on the scalp where we listen in on the brain, are specific to the conditions we are trying to address, and specific to the individual.
What is Biofeedback?Biofeedback is a type of non-invasive treatment that provides real-time information on brain or body functions. It uses computer technology to record physiological activity that is normally outside conscious awareness (e.g. heart rate, breathing rate, and muscle tension) and to display this activity to the person being recorded.
The goal of biofeedback is to teach people to build awareness of patterns of physiological stress and to voluntarily control their physiological activity.
Heart Rate Variability training(For Stress, Emotional Reactivity and Cognitive Enhancement)
Research has shown that the degree of 'speed-up' and 'slow-down' of the heart - known as Heart Rate Variability (HRV) has profound implications for health and well being. It has been shown that HRV can be modified through Biofeedback training. A number of medical and psychological conditions are now being treated by HRV training, including anxiety, excessive anger, cardiac condition, asthma, irritable bowel syndrome, chronic pain, chronic fatigue syndrome, and , chronic obstructive pulmonary disorder (COPD).
Heart Rate Variability Biofeedback is a new technique for training people to change the variability and dominant rhythms in their heart activity. The heart is a bio-electrical pump beating at an ever changing rate, and this change or variability, is adaptive and is necessary in order to maintain a healthy heart. If you suffer mental or emotional stress, or become depressed, this variability decreases and the heart does not function so well. On the other hand, high HRV is associated with better health and survival from illness.
Recent research has now shown it is possible to increase your own HRV using biofeedback. So, if you are frequently stressed and perhaps suffer from one or more of the stress-related illnesses, you can learn to increase your HRV and be on your way to a healthier mind and body. Initial case reports have shown success with HRV biofeedback in reducing anger and anxiety disorders, asthma, cardiovascular disorders, chronic fatigue, chronic pain, essential hypertension and irritable bowel syndrome -228600319405 (Lehrer et al, 2004; Lehrer et al, 2006; Hassett et al, 2007).
Thermal Biofeedback training(For Stress Management, Headache Prevention, Insomnia and Attention Regulation)
Chronic stress is associated with hypertension (high blood pressure), migraines, tension headaches, digestive problems, anxiety, and mood disorders. Under stress, blood vessels in hands and feet constrict and core muscles constrict to keep organs tight and deactivated in preparation for a response to a stressor. As a result, there is less peripheral blood flow, which is typically associated with lower skin temperature. So, skin temperature is an index of stress-related arousal.
A feedback thermometer, usually attached to a finger, detects skin temperature in degrees Celsius or Fahrenheit. Awareness of this arousal can help reduce stress and facilitate relaxation practice.
Galvanic Stress Response training(For emotional reactivity and stress management; GSR)
Electrodermograph (EDG) provides one of the fastest and most sensitive measures of stress.
The activity of sweat glands in the palms of the hands precisely reflects a person's level of emotional arousal. Mental agitation is expressed almost immediately (within .5 to 3 seconds) in the amount of sweat on the surface of the skin.
This can be detected by measuring the conductance of electricity across the hands hands or fingers (the electric current cannot be felt by the user). Skin Conductance Level (SCL) also known as Galvanic Skin Response (GSR) is measured in kΩ (thousands of ohms). This technology has been used for decades as the basis for the classic "Lie detector" test. SCL is also widely used to increase people's awareness of their emotions and for the reduction of stress, anxiety, high blood pressure, and insomnia.
Surface Electromyography (sEMG) Biofeedback
Muscle tension is at the root of several stress-related problems including headaches, back and neck pain, temporomandibular joint disorder (TMD). It is also an important symptom of anxiety, worry, stress, and mood problems.
With EMG, electrodes on the skin pick up activity from underlying muscles (measured in microvolts) and provide feedback about the state of the muscles. You can uses this information to increase awareness and reduce tension in those muscles.
Live Z Score training in Functional ConnectivityThe concept of Z score biofeedback (also known as Z-Score Neurofeedback) in order to identify brain regions that are de-regulated and depart from expected values in real-time.
TreatmentTreatment with EEG neurofeedback is based on the theory that once individuals understand their brain activity and learn to manipulate their own brain waves, they will be able to continue to do so, long after the therapy has ended. Some studies have followed patients for as long as 10 years after being treated with EEG neurofeedback and have shown no significant loss of treatment gains.

The frequencies we target, and the specific locations on the scalp where we listen in on the brain, are specific to the conditions we are trying to address, and specific to the individual.
We also use 19 Channel Neurofeedback
Unlike our normal one or two electrode neurofeedback training protocols, where we mainly concentrate on lowering the power in one specific region of the brain, 19 channel neurofeedback (also know as Z-score neurofeedback or “full cap” neurofeedback) can train up to 5700 variables at one time.
19 channel neurofeedback trains your brain using z-scores. This can be thought of as “real time” training where your brain is getting trained to be within normal limits as defined by a normative database in real time.
19 channel neurofeedback can train EEG coherence, phase delay, amplitude and power asymmetry, phase reset, phase lock and phase shift duration.

Trancranial Magnetic Stimulation (rTMS)
What is rTMS?Transcranial Magnetic stimulation rTMS is a procedure in which cerebral electrical activity is influenced by a pulsed magnetic field. The magnetic field is generated by passing brief current pulses through a figure 8 coil. This coil is encased in plastic and is held close to the scalp so that the magnetic field can be focused onto specific areas of the cortex, or surface, of the brain.
rTMS therapy was approved by Health Canada for clinical delivery in Canada.
APPROVED by Health Canada
The magnetic field that is generated in rTMS can penetrate the scalp and skull safely and painlessly to induce a current in specific regions of the brain. It is termed repetitive TMS, or rTMS, because the magnetic stimulation is delivered at regular intervals.
Many aspects of rTMS, referred to as stimulation parameters, can be changed. The ability to change parameters while directly targeting specific brain areas suggests that rTMS has valuable therapeutic potential.
This means that the delivery of rTMS therapy may be customized for each patient. It also suggests that rTMS may be used to elicit certain desired effects in the brain (i.e. excitatory or inhibitory effects) that have shown promise for treating various conditions or illnesses such as depression. rTMS may be used to elicit certain desired effects in the brain (i.e. excitatory or inhibitory effects) that have shown promise for treating various conditions or illnesses such as:
- Post concussive symptoms
- Neuropathic pain
DepressionIn treating depression, rTMS therapy targets the area in the left cerebral hemisphere just a few inches above the temple and beneath the skull. This area is called the left dorsolateral prefrontal cortex (L-DLPFC, see photo). The L-DLPFC is readily accessible to the magnetic field and is highly interconnected with limbic structures, which play a dominant role in mood modulation and major depression.
rTMS is used to treat depression by inducing a current in the L-DLPFC with stimulation by a magnetic field. The stimulations are short but intense, lasting less than a millisecond. The penetration itself holds little energy. Several studies have suggested that rTMS regulates beta adreno-receptors and increases dopamine and serotonin levels.
Some remote brain structures are also believed to be linked to depression. rTMS may alter activity in these structures not directly accessible to the rTMS coil by focal cortical stimulation. The indirect stimulation occurs via trans-synaptic effects. This means that the accessible areas of the brain, such as the L-DLPFC described above, are first directly stimulated by the magnetic field. This direct stimulation may in turn cause the inaccessible areas of the brain to be stimulated.
The human brain is a natural electrical organ that functions by transmitting electrical signals from one nerve cell to another. Brain imaging techniques demonstrate that individuals suffering from depression often display insufficient levels of glucose metabolism, lower blood flow in the L-DLPFC and increased activity in the limbic system.
rTMS acts on this process by regulating the flow of interactions between neurons that will appropriately increase or decrease the desired regions to relieve the depression.
Acute treatment for depression consists of 20-30 rTMS sessions, over 4-6 consecutive weeks (excluding weekends).
Transcranial direct current stimulation (tDCS)
What is Transcranial Direct Current Stimulation (tDCS)Transcranial direct current stimulation (tDCS), is a non-invasive, painless brain stimulation treatment that uses direct electrical currents to stimulate specific parts of the brain.
The Therapy works by delivering a low intensity electrical current to part of the brain responsible for abnormal pain sensation. This constant, low intensity current is passed through two electrodes placed over the head which modulates neuronal activity.
The treatment is not surgical and drug free.For patients this means less complications and less risk. If you are suffering from Fibromyalgia or Migraine you may benefit from this new technology.
• There are two types of stimulation with tDCS: anodal and cathodal stimulation.
Anodal stimulation acts to excite neuronal activity while cathodal stimulation inhibits or reduces neuronal activity.

Are Transcranial Direct Current Stimulation (tDCS) Effective?
Recent studies support a therapeutic potential of tDCS in patients with chronic neuropathic pain, Parkinson, stroke recovery, tinnitus (ringing in the ears), traumatic spinal cord injury, depression and other illnesses. tDCS has not been approved by the FDA for any therapeutic applications, thus treatments are considered an “off-label” application.
Although tDCS is still an experimental form of brain stimulation, it potentially has several advantages over other brain stimulation techniques. It is cheap, non-invasive, painless and safe. It is also easy to administer and the equipment is easily portable.
Several studies suggest it may be a valuable tool for the treatment of neuropsychiatric conditions such as depression, anxiety, Parkinson’s disease, and chronic pain. Research has also demonstrated cognitive improvement in some patients undergoing tDCS. Currently, tDCS is not an FDA-approved treatment.

Passive Infrared Hemoencephalography (pIR HEG)
Passive Infrared Hemoencephalography (pIR HEG)
What is Passive Infrared (pIR HEG)?PASSIVE INFRARED HEMOENCEPHALOGRAPHY refers to a variant of that technique. It utilizes physiological signals from the brain, but these signals are based on thermal output, arising from changes in blood flow dynamics and cellular metabolism.
How Does pIR-HEG Neurofeedback Work?Blood flow is increased at the prefrontal cortex with attentional brain activity. By achieving focused attention with a relaxed body and mind, the neurofeedback participant is able manipulate the computer sensor output that is measuring blood flow. The trainee learns how to increase activation of important brain activities and eventually can retrain the brain to perform better.
The Passive Infrared (pIR HEG) process is simple to learn and often enjoyable.
