The brain is the organ of the body that handles more functions than any other organ. In the brain all our thoughts and conscious ideas occur, but there are also carried out many other activities that we hardly notice during our daily lives.

In the brain are carried out may complex and varied processes. Some of these are vision, hearing, memory, sensations anywhere in the body, controlling the position in space, balance. Also are included judgment, the ability to abstract, dreaming, control of voluntary movements, including the most accurate and the most vigorous ones, etc.

It is also in the brain that many functions known as vegetative are regulated, this is carried out independently of consciousness, will and intelligence of the individual. These activities contribute to the growth of the body, the general welfare, food, and nutrition, i.e., the individual’s adaptation to its environment.

Examples of such functions are found in the regulation of cardiovascular functions, production of various hormones that in turn regulate a large number of glands in the body. Also regulation of temperature, bowel movement, breathing, perspiration control, etc.

To carry out what is mentioned above, the brain requires a structure that is capable enough to process a lot of information in the least amount of time. The brain can select thousands of different messages for both input and output and thus it can be channeled to places of suitable processing.

It is well known that the brain weighs about three pounds and is made up of neurons and glia. In this mass of tissue that fits inside our skull, there are more cells than all the stars that are estimated in the universe.

The cellular communication depends on the axons of protected neurons. Axons make fast and safe the conveyed message, supporting this anatomic complexity and connections between neurons as efficiently as possible. Such thing is achieved by a cover myelin; and that the message is transmitted by a type of molecules known as neurotransmitters.

The brain is protected of sudden hits by the skull bone, to keep the integrity of the entire system. The movement of the brain inside the head is rather limited because of the cover of specific membranes known as meninges.

But perhaps most important of all this is the fact that to preserve brain health is necessary, keep both the macroscopic and the microscopic structure and dynamism. We’ve recently Tweeted about this as well.

Brain health depends on preventing neurons of dying. Also that they have electrical activity and produce specific neurotransmitters. It is also required that these neurotransmitters are released and can transmit a signal between a neuron and another. Appropriate connections established among various types of neurons are needed as well as these connections can be carried out in multiple areas of the brain and a long lifetime.

A new field of medicine studies the effect of various types of drugs known as nootropics. These drugs are attributed precisely the effect to maintain, stimulate and where appropriate regenerate brain health through diverse mechanisms of action on neuronal activity, structure and connectivity.
