human Brain 

The human brain is a mass of 1.4 kg composed of fats and gelatinous tissues and is the most complex of all known living structures. Up to one billion nerve cells work together to coordinate physical activities and mental processes that distinguish humans from other species.


The brain is the most complex organ in the human body, and perhaps the most remarkable. Start finding out how it works with our beginner's guide

This body allows us to feel , think, imagine , move, learn, talk and more.
In this room we can get in touch with the complex and wonderful field of neuroscience . It explains in great detail how the nervous system is formed and the processes that are generated in response to all the stimuli around us.

Main ideas : addictions , learning, emotions , language, memory, neurons, thoughts , senses, nervous system synapses.

The room has the following sections.

Organization and structure of the nervous system

This section explains that the nervous system consists of a central nervous system consists of the brain, the cerebellum , stem and spinal cord , and peripheral nervous system composed of nerves, ganglia and intestinal neuronal network.
All nervous system structures regulate many different functions thanks to billions of cells are connected together to form circuits having the property of transmitting information through electrical and chemical signals .

The language of the brain

For any action from a simple muscle movement to the most complicated intellectual task , it is essential that neurons communicate efficiently. This communication is that the electrical pulses generated neurons transmit information through the dendrites of a neuron to another axons .

The evolution of the nervous system

The diversity of living organisms with a nervous system has to be differentiated with advancing evolutionary scale. The human nervous system is distinguished by its large expansion of the cerebral cortex, particularly in areas associated with language and with certain properties of higher consciousness .

The brain and senses

Interaction with the environment is possible because all the animals we have sensory systems that perceive our environment. Such systems are formed by neural circuits which detect and transmit sensations to the brain cortex . That other neuronal circuits that interpret and analyze sensory information exist, respond accordingly with data and plan the actions that need to be performed.

Neuronal plasticity , learning and memory

The brain can alter its operation when there are changes in the external environment . This ability to change and adapt the brain is called brain plasticity . Thanks to this , the individual can learn and adapt to the demands of changing environments constantly.
Learning and memory are powerful expressions of the plastic capacity of our brains.

biological rhythms

Although sleeping and waking thought arise from our habits, the truth is that they are the result of internal biological clocks that determine not only the time and duration of sleep , but most of the body functions that vary regularly.
All living beings have an internal clock that helps regulate the times when we do activities like eating, sleeping , reproducing and even live with other animals.

Brain and Thought

Another feature that distinguishes the human brain is his mental ability to sort , make sense and interpret the information available to the brain . Thinking allows us to combine the information we perceive , memorize and reason to form new concepts or make decisions regarding this problem.
We use thought to solve situations mentally exploring various solutions to understand spoken or written language and to produce new ideas that we can communicate to others.

Emotions and the Brain

Each person experiences a particular emotion , depending on their prior experiences , learning, character and situation. However emotions change our inner workings very accurately : the glands begin to produce substances, breathing quickens or pauses , and may change the tension of our muscles and our position. We have little control over our physiological responses to emotion ; so we can not help ourselves to the beloved red or prevent heart race when we feel the danger.

When the brain is diseased

The brain and the whole nervous system is at constant risk of diminishing their duties due to age , illness or abuse of harmful substances. Although brain tissue tries to repair the damage, this is not always possible.


Learn how the brain works allows us to understand diseases that affect both psychiatric and neurological, and find more efficient and safe treatments nervous system.
