A quantitative electroencephalogram, commonly abbreviated as qEEG, is a tool used to measure electrical activity and overall functioning of the brain. It is also referred to as brain mapping, where brainwaves (the electrical impulses generated through the millions of neurons in the brain) are studied regarding how they communicate. 

Through these signals, it can reveal information about brain functioning such as thought patterns, stress levels, as well as emotions. 

Below we share everything you need to know about qEEG brain mapping. 

Defining QEEG & Brain Mapping

As mentioned, quantitative electroencephalography is a procedure where the brain’s processes are recorded using a computer. The data gathered is then processed through various algorithms through the use of modern applications such as wavelet analysis. 

Next, the data is compared with normative database reference values and then converted into brain maps, where the processed EEG is indicated by color. 

The information gathered from qEEG and EEG can then be used as a tool to evaluate a person’s brain function, as well as track changes in the brain from medication or neurofeedback.

As a result, qEEG processing techniques can give us a glimpse into the dynamic changes that take place in the brain during any cognitive process. This approach can also be used to help determine which areas of our brains are processing effectively and engaged. 

QEEG vs. EEG: What’s the Difference?

When undergoing EEG, or normal electroencephalography, small metal discs will be placed on a patient’s scalp, which is used to detect the brain’s electrical activity. This neurofeedback equipment is then be used to map out the brain’s functioning— these are typically used to detect changes in a patient’s brain activity as they are exposed to various sensations or stimuli. Using this data, psychologists and physicians will be able to detect possible injuries or diagnose brain disorders. 

On the other hand, a qEEG is the same process but with the added benefits of quantitative analysis during or after the scans are done. In other words, qEEG processes recorded electrical activity from the brain and presents data in a more three-dimensional manner. Apart from being able to detect the same conditions or disorders that an EEG can, a qEEG can also detect the following: 

– Anxiety disorders

– Cognitive inflexibility 

– Impulsive tendencies 

– Poor emotional management

– And more 

Who Can Benefit from Brain Mapping?

Anyone can benefit from brain mapping, and it can be performed on individuals of any age, including children, adolescents, adults, and even babies. 

Someone who struggles with mental health symptoms could benefit from evaluations with qEEG tests. With the help of a specialist, you might be able to identify various conditions, such as: 

– Depression

– Panic disorder

– ADHD

– Schizophrenia

– PTSD

– Dementia

– Obsessive-compulsive disorder

– Sleep problems

What Does QEEG Brain Mapping Show Us?

A brain map report will contain many pages of data that may show various parts of your brain function. More specifically, a brain map will allow us to see if parts of the brain are working properly or not. 

It can help us confirm various conditions such as: 

– Epilepsy

– Brain tumors

– Seizures

– Head injuries

– Memory problems

Doctors can also find out many other important details through the use of brain mapping such as: 

– Trouble handling emotions 

– Difficulty in paying attention 

– Poor problem-solving skills 

Types of Brainwaves

Because the brain is the strongest electromagnetic engine in the world, it’s capable of doing many things, using neurotransmitters and electricity to help us act, feel, and think. 

Around 100 billion neurons in the brain work to keep the flow of electricity moving throughout the body, allowing signals to travel at amazing speeds. These electrical impulses can also communicate with each other and create synchronized pulses or brainwaves. 

Overall, there are 4 kinds of brainwave patterns, including: 

– Beta brainwaves: These run between 13 to 24 cycles per second and are fast-occurring waves during mental work or concentration states

– Alpha brainwaves: These run at 8 to 12 cycles per second and are present during relaxed states 

– Theta brainwaves: These run at 5 to 7 cycles per second and are known as slow brain waves that appear during relaxation, twilight, or daydreaming states

– Delta brainwaves: These run at 1 to 4 cycles per second and are very slow-moving, occurring mostly in our sleep

Is QEEG Used During Neurofeedback Therapy?

Neurofeedback therapy is a non-invasive way of measuring and controlling your brainwaves. This kind of therapy allows the neurofeedback provider to keep any involuntary body processes through conditioning. Many conditions, such as anxiety, ADHD, and depression will usually occur because our brainwaves aren’t balanced perfectly. 

Undergoing neurofeedback therapy can help us bring specific areas of the brain back to their healthy state. 

When treatment begins, doctors can map out the areas of the brain through qEEG, which can help to identify which areas of the brain need to be put back in the right place. Once they are able to find the necessary information, neurofeedback therapy can be customized to work in the areas that need improvement. 

During a session, patients will have sensors placed around the target areas of the head to see its current state compared to what it needs to look like. 

Music and sounds played on headphones will further help with the process of pushing the brain to a comfortable state. Through repetition, this non-invasive, drug-free, and pain-free option will allow you to retrain various regions of the brain to bring you back to the right state of balance.
