Neuro and biofeedback

What is Neurofeedback?

Neurofeedback is a brain self-regulation training method based on the principles of neuroplasticity and operant conditioning.

During neurofeedback training, an individual receives real-time feedback about their brain activity and gradually learns to modify it, improving regulation of attention, emotions, and behavior.

This method has been used for over 40 years and is supported by a substantial scientific and clinical evidence base.

It is applied in:

• psychology and psychotherapy

• neuropsychology

• rehabilitation

• cognitive and athletic performance training

Neurofeedback has also been used in organizations such as NASA and is widely applied by specialists in the United States and Europe.

 

How Neurotherapy Works

Neurotherapy trains the brain to develop more optimal EEG patterns using positive reinforcement.

During a session, the client is connected to EEG sensors that continuously monitor brain activity. These signals are linked to a computer system — for example, a simple game may be controlled by brain activity.

Real-time feedback is delivered through visual or auditory signals. When the brain produces more optimal patterns, the feedback becomes clearer or more rewarding (e.g., brighter visuals). When activity becomes less optimal, the feedback diminishes.

Over time, the brain learns to maintain more efficient and stable activity patterns.

 

Applications of Neurofeedback

Neurofeedback is used to support a wide range of conditions, including:

• anxiety

• depression

• insomnia

• attention difficulties

• cognitive challenges

• emotional regulation difficulties

• headaches and chronic pain

✔ The American Psychological Association recognizes neurofeedback as an evidence-based method

✔ The American Academy of Pediatrics classified neurofeedback as a Level 1 (highest level) intervention for ADHD (2012)

✔ The Substance Abuse and Mental Health Services Administration (SAMHSA) included neurofeedback protocols in the National Registry of Evidence-based Programs and Practices (NREPP)

This means neurofeedback is not an experimental method, but an evidence-based approach when applied correctly.

 

Types of Neurofeedback

Different approaches are used depending on the goal:

• Power/Frequency Neurofeedback

• SCP (Slow Cortical Potentials)

• LENS (Low Energy Neurofeedback System)

• HEG (hemoencephalography)

• Z-score Neurofeedback

• LORETA

• fMRI Neurofeedback

 

What Happens During a Session

During a session, the client sits comfortably while sensors are placed on the scalp. The procedure is completely painless and similar to a standard EEG recording.

Sessions typically last between 30 and 60 minutes.
A full program usually includes 30–40 sessions, depending on individual needs.

 

Effectiveness

When properly designed, neurofeedback programs can reach effectiveness levels of up to 90%.

However, outcomes depend on:

• individual brain characteristics

• lifestyle

• stress levels

• overall health

• level of engagement

Some individuals respond quickly, while others progress gradually.

 

When Neurofeedback May Need to Be Postponed

Certain conditions may reduce effectiveness or require stabilization first:

• Medication factors (e.g., benzodiazepines, medication changes)

• Psychiatric conditions (active addiction, suicidal behavior, severe eating disorders)

• Psychosocial stress (violence, bullying, chronic stress)

• Systemic factors (inflammation, hormonal imbalance, metabolic issues, nutritional deficiencies)

The brain always functions within the context of the whole organism.

 

What to Expect

After the first 4-5 sessions:

• increased calmness

• improved focus

• better sleep

After 20+ sessions:

• more stable and lasting changes

 

What is EEG / QEEG

EEG measures brain activity (brainwaves).

QEEG (quantitative EEG) is a statistical and computational analysis of EEG data. It allows us to understand:

• how the brain supports cognitive and emotional functions

• how different regions communicate

• where regulation may be inefficient

QEEG data is often visualized as brain maps, which help guide individualized neurofeedback protocols.

 

Important

Neurofeedback is not a universal solution.
It is a tool whose effectiveness depends on:

• accurate assessment

• correct protocol selection

• timing of intervention

• overall physiological and environmental context

The key question is not “Does it work?” its effectiveness is well established, but rather:
“Is it appropriate for this individual at this moment, and in what form and protocol?”
