In the last decade, neuroscientists have revealed that disorders such as anxiety, AD / HD, depression, addictions, epilepsy, and dysfunctions such as chronic stress, obsessions and insomnia in others are the result of an imbalance in the functioning of different brain regions.

Neurofeedback is a form of training developed by neuroscientists, with which these imbalances, responsible for the symptoms and difficulties, are corrected in a non-invasive and lasting way, and without the use of medication. Brain training acts on the root of the problem at brain level, producing profound improvements with long-lasting effects.

Biofeedback is a method by which biological processes (such as skin temperature, heart rate, or brain waves) are recorded and measured to help the person gain control of this normally involuntary activity,. It is used to combat stress and anxiety, as well as to treat chronic pain and migraines.

Neurofeedback records brain waves, obtained through sensors located on the scalp (quantitative electroencephalogram or EEG). The recorded waves are interpreted in a computer and allow us to observe which areas of the brain are functioning incorrectly, causing symptoms and difficulties.

While the training session is being carried out, the computer gives audiovisual instructions (in the form of an exercise or a video game) to activate or deactivate specific brain regions. If the brain is following the exercise well, the audiovisual continues; if, on the contrary, erroneous processes are detected, the video game or audiovisual stops. Like this, the brain begins to learn what to do to reduce the brain waves that cause difficulties and increase the waves associated with better function. With repetition, the brain will consolidate what it has learned and will be able to stay in that state after treatment.

Neurofeedback allows for a renewal or improvement of the neuronal connection and the prevention of brain aging through the enhancement of the cognitive reserve.

By “cognitive reserve” we mean the cognitive capacity accumulated during a lifetime, a capacity that does not prevent the appearance of these diseases, but that can mitigate their symptoms.

Brain training is one of those activities that leads to a greater cognitive reserve.

What does Neurofeedback therapy consist of?

Neurofeedback therapy was developed through various investigations which started with the first electroencephalogram and the discovery of brain waves by Hans Berger in the 1920s.

It is a non-invasive therapy, which acts directly on brain functions causing an effective efficacy that is maintained over time.

The procedure consists of a first evaluation of brain activity by performing an EEG by placing 19 sensors located in the skull. As a result, this gives us a complete brain mapping that indicates which areas require work, that is, those areas with the greatest and least activity, which provide us with the necessary information for the third part of the treatment, where the patient performs cognitive training with visual and auditory stimulation.

Attention, memory, processing speed, visual and auditory processing, and reasoning, are basic to improve the learning capacity of any person.

The brain, a plastic organ


The brain is made of more than 100 billion neurons. The first investigations considered that neurogenesis stopped shortly after birth, but today we know that the brain has the ability to reorganize its neural pathways, create new connections, and even create new neurons as in the hippocampus. This finding revolutionized the concept of the brain, disproving the belief that it was the only organ unable to regenerate, and therefore static.

All of this implies that we can learn and relearn, since our brain behaves as a plastic and flexible organ throughout our life cycle. Neurogenesis can be affected by the influence of various positive factors such as learning, cognitive stimulation, physical exercise, hormonal influence, and also negative factors such as acute and chronic stress, psychiatric illnesses such as depression, etc …

Brain Plasticity

Neuronal plasticity is the set of modifications that occur in the nervous system as a result of the environment. Experience continually modifies our brain, strengthening or weakening the synapses that connect neurons. This process is known as learning. Regardless of the natural decline that old age brings, learning can produce new neurons, and our intelligence is not fixed or immutable.

Neurofeedback provides brain work in each training, promoting stronger connections or helping to create new synaptic networks in different brain areas, therefore providing cognitive improvement.

Neurofeedback as a brain enhancer

Who can train the brain?

This training is suitable for children, teenagers, adults, athletes, and elderly people, without any contraindication. It is indicated for anyone who wants to promote their abilities or prevent cognitive aging. Brain gymnastics with neurofeedback, as if it were a physical training, allow greater resistance to perform tasks easier and faster. Our programs are individualized and are carried out with a previous brain mapping that indicates the state of the brain and the areas to improve.
