What is brain activity and how is it measured?
The brain's electrical activity is a continuous, dynamic process that reflects the complex communication between the billions of neurons in the brain. These neurons communicate with one another through electrical impulses, creating brainwave patterns that can be measured and analysed. The waves are classified by frequency into delta, theta, alpha, beta and gamma waves, each associated with different mental states and cognitive activities. For example, delta waves are predominant in deep sleep, while beta waves are associated with intense mental activity and states of alertness.
Every individual has a unique "electrical signature" of their own brain, and this activity can be measured and analysed to provide valuable information about how the brain works and about a person's mental state. The main methods for measuring brain activity include electroencephalography (EEG) and quantitative electroencephalography mapping (qEEG), each with its own particularities and advantages. Over recent decades, research has shown that the brain's electrical activity can be modulated through various methods, including neurofeedback, which opens up new prospects for improving mental and cognitive health.
EEG (Electroencephalography)
EEG is a non-invasive technique that measures the brain's electrical activity using sensors placed on the scalp. These electrodes pick up the electrical signals generated by neuronal activity and transmit them to a device that records the signals in the form of waves. EEG is frequently used to diagnose and monitor neurological disorders such as epilepsy, sleep disorders and encephalopathies.
qEEG (Quantitative electroencephalography or Brain Map)
qEEG is an advanced, specialised version of traditional EEG. This method does not merely record the brain's electrical activity, it also analyses it quantitatively. Once the EEG signals are captured, they are processed and turned into a detailed map of brain activity called a BrainMap. This map can highlight specific patterns of neuronal activity and is often used to identify subtle brain dysfunctions that may be linked to various mental and neurological disorders, such as ADHD, anxiety, depression and autism spectrum disorders. A major advantage of qEEG is its ability to provide a detailed, objective analysis of brain functioning, which can guide personalised therapeutic interventions.
What is neuroplasticity?
Neuroplasticity is the brain's remarkable ability to reorganise and adapt following experience, learning and injury. This capacity relies on the formation and reorganisation of the synaptic connections between neurons, which allows the brain to adapt to new information, develop new skills and recover functions lost as a result of trauma. Neuroplasticity is essential for learning and memory processes, and its importance becomes evident in a wide range of contexts, from rehabilitation after a stroke to adapting to changes in the environment.
Neurofeedback is closely tied to the concept of neuroplasticity because it rests on the principle that, by providing real-time feedback about brain activity, the brain can learn to regulate and optimise its own neuronal functioning. This process of self-regulation and learning stimulates neuroplasticity, since it involves modifying brain activity patterns according to the feedback received. For example, when a person learns to calm excessive beta waves over certain brain regions associated with anxiety or chronic stress, that process of learning and adaptation reflects neuroplastic changes in the brain.
Through repeated, consistent neurofeedback sessions, the brain forms new neural pathways or strengthens the beneficial ones it already has, thereby improving cognitive and emotional functions. This is particularly useful in treating neurological and psychological disorders, but also in enhancing performance. Studies have shown that, by stimulating neuroplasticity, neurofeedback can produce lasting changes in how the brain works, leading to long-term benefits for mental health.
How do brain training and neurotherapy work?
Neurotherapy, also known as neurofeedback, works by monitoring brain activity and providing real-time feedback on it, helping people to self-regulate and optimise their neuronal functioning. During a neurotherapy session, sensors placed on the scalp measure the brain's electrical activity, which is then displayed on a screen in the form of brainwaves. The patient is exposed to various types of feedback, such as sounds or images, which change according to the brain activity recorded. Through this immediate feedback, the brain adjusts its dysfunctional activity patterns. With repeated sessions, these changes become more stable and lasting thanks to neuroplasticity, resulting in significant improvements in cognitive functions, emotional state and overall brain functioning.
The benefits of neuronal training
Neuronal training, or neurofeedback, offers a wide range of benefits that can influence many aspects of life, from health, personal relationships and career to academic and athletic performance. These benefits are the direct result of neurofeedback's capacity to optimise brain functioning by regulating neuronal activity.
Personal relationships
An essential aspect of personal relationships is recognising, expressing and effectively managing emotions, along with communication skills. Neurofeedback can improve emotional regulation, reducing anxiety and depression, and it can help with managing stress or anger. People who are better able to control their emotions tend to have more harmonious relationships and fewer conflicts. Neurofeedback can also improve empathy and the ability to understand and respond to other people's emotions, making social interactions more positive.
Career
In the professional arena, neurofeedback can have a significant impact by improving focus, memory and overall cognitive performance. This is especially valuable in stressful or cognitively demanding work environments. A greater capacity to manage stress and anxiety can lead to higher productivity and better decision-making. People who use neurofeedback may notice a reduction in mental exhaustion and an increase in resilience to stress, which leads to a better balance between professional and personal life.
School
For pupils and students, neurofeedback can improve academic performance by increasing the capacity for concentration and attention. This is particularly useful for those with attention disorders, such as ADHD. Improving working memory and the ability to sustain attention for longer periods can lead to better school results and a better grasp of the study material. Reducing anxiety linked to exams and performance can also foster a more positive and productive learning environment.
Athletic performance
Athletes can benefit from neurofeedback through the optimisation of cognitive functions and the reduction of performance anxiety. The ability to enter a state of "flow" or peak concentration can be enhanced, which can translate into superior athletic performance. Managing stress and pressure can also improve responses in critical situations and contribute to faster recovery after training or competition. Neuronal training can help athletes develop effective mental strategies, thereby increasing mental resilience and motivation.
Mental health and general wellbeing
In a broader context, neurofeedback can contribute to better mental health and greater overall wellbeing. Reducing the symptoms associated with various mental disorders, such as depression, anxiety and PTSD, can significantly improve quality of life. Better sleep quality, improved mood and higher general energy levels are other important benefits that can result from regular neuronal training. People who use neurofeedback often report a greater sense of control over their own lives and a greater capacity to cope with everyday challenges.
