In order to learn something we need to use the right hemisphere of
the brain more, but when we reach a certain level of skill, these
activities become controlled by the left hemisphere of the brain.
Neurones are specific cells of our brain. There are 100.000 million
neurones at our disposal. One produces a minimum of 1000 connections or
synapses per neurone. The synapse permits communication between the
neurones. This possibility of communicating between each other is
specific to the nerve cells or neurones.
Two types of cellular extension derive from the cellular body of the
neurone: the axon and the dendrites.
pathway through which the neurones transmit information to each other,
from the pre-synaptic cell to a post-synaptic cell, thanks to the
connection or synapse they establish.
extensions of the cellular body. They divide themselves like branches
of a tree and act as receptors for the signals arriving from other
Dendrites are the entrances whilst the axons represent the exits.
After travelling along the axon, and arriving at the end of a neurone,
the electrical impulse causes little vesicles containing the
neurotransmitter (chemical) to open. This diffuses across the
intercellular space and arrives at the next cell membrane where it
generates a new electrical signal, using mechanisms which are very
complex but perfectly understood.
As the signals are transmitted through the axon, in the form of
electrical impulses and given the importance of the length of the axon
(in comparison with the thousandth of a millimetre that the neurone
measures) nature has created an insulating layer that completely
surrounds the axon. This insulation is formed by cells called Schwann
cells that contain myelin (a very insulating fatty substance) and which
wrap themselves around the axon, like the insulating covering of a
As we can see, the communication between neurones is electrical,
chemical and again electrical. One can measure this electrical activity
by means of an electroencephalogram (EEG).
Brain-waves, emanating from the hemispheres and detected by the EEG,
are the reflection of the electrical activity of the brain. These waves
have been classified according to their frequency and specific states
of consciousness. Here are the main ones:
Two important types of neurones exist: the excitatory neurones and the
inhibitory neurones which slow down the activity of the excitatory
In order for the brain to function adequately, it is important that
there is a certain balance between these two types of neurones. If an
imbalance exists, major or minor disorders can manifest.
A neural imbalance can be corrected thanks to the NeurOptimal®
feedback method. Weak connections receive a boost and are rebalanced
little by little, which helps to achieve a greater emotional stability
and psychological wellbeing.
