What is Neurofeedback
Neurofeedback as a brain enhancer
Neurofeedback allows a renovation or an improvement of neuronal connections to occur and it also protects against neuronal aging by means of a preservation of cognitive reserve.
With the term cognitive reserve we refer to the cognitive capacity gathered through life which doesn´t prevent the disease from affecting the brain, but it can protect against the rapid worsening of the symptoms.
Cerebral training is one of these activities which leads to having a greater cognitive reserve.
Neurofeedback was developed in 1920 after studies carried out following the discovery of brain waves and electroencephalogram by Hans Berger.
Neurofeedback is a non invasive technique which directly works on cerebral functioning leading to long-lasting changes in brain activity.
The procedure consists of a primary evaluation of cerebral activity by means of an EEG session. In order to perform an electroencephalogram we place a cap of 19 electrodes on the head which registers and transmits a brain map of electrical activity. This brain map allows us to know which are the areas and the functional connections between areas that we need to work on during the training with neurofeedback.
Attention, memory, processing speed, auditory and visual processing and reasoning are fundamental keys in order to improve someone’s learning ability.
The brain consists of more than 100 billion neurons. First scientific studies thought that neurogenesis would stop after birth, but nowadays we know that the brain has the capacity to reorganize its networks, to delete and create new ones and even create new neurons throughout its lifespan. This means that we can always learn and relearn since the brain is a maluable organ which changes throughout life.
Neurogenesis can be affected by different positive factors such as learning, cognitive stimulation, physical exercise, hormonal influence and at the same time by negative ones such as high and chronic stress, psychiatric illnesses such as depression, anxiety etc.
With this term we refer to the combination of changes that are generated in our nervous system as a result of environmental influences. Our experiences constantly shape our brain, by strengthening or weakening specific connections among brain areas. This process is known as learning.
Neurofeedback contributes to learning by creating new and stronger connections among brain areas thus creating an improvement in cognitive functioning.
