The chief commander of our central nervous system is the Mind. It contains billions of neurons each linked to other neurons by synapses. They communicate via axons that take the messages to our body cells. Our brain has unique capabilities to acquire, understand, process and store information.
Brain researchers are quite familiar and knowledgeable about the operations of individual human brain cells, however , they still do not understand the way brain cells work in groups of millions of cells. Some would consider the brain to be like a biological computer, however this presumption and modelling is far from truth and cannot simulate the complexity of the brain.
The basic brain functions such as breathing, regulating heart beats, controlling movement and other basic skills had been known to scientific researchers from precious records first appeared in worms a lot of million years ago. Since then our brain went through evolution processes of obtaining more and more sophisticated functions and exclusive abilities. These abilities include among others emotional, sexual and fighting behaviors located in newly evolved brain areas.
The brain needs continuous supply of oxygen and glucose for its function. These needs are supplied by the bloodstream system. Our brain needs the nourishments like the rest of our body. For this reason we feel at our best mental function after a healthy meal or even slow and tired when we have a tendency eat sufficiently on time or consume unhealthy food.
Our brain’s primary energy source is carbo fuel. Our body has got the capability to convert carbohydrates from foods such as oatmeal or brown grain into glucose. Accordingly, we have to generate a daily supply of about 60% in our calories from carbohydrates.
To build neurotransmitters or chemicals that allow mind cells to communicate, our human brain needs protein, such as: egg white-colored, seafood or beans. Our body breaks down the protein into amino-acids which usually affect our cognition and feeling, such as dopamine, which help us to become alert. In addition to protein, our human brain needs fatty acids, which are generated through Omega-3&6 fatty acids, olive oil and wholegrain. Our brain also needs a range of vitamins and minerals such as vitamins B, Electronic, magnesium, calcium and iron. To obtain those vitamins we have to eat fresh food in various colors.
Brain capacity is unknown.

We know that our mind have a lot of storage capacity and processing power, but we how to start how to estimate its actual capability. A popular assumption is that our brain’s capacity is 10 times more than anybody’s estimate.
Our brain includes trillions of neurons, with a large numbers of complex interconnections. What vary from brain-to-brain are the types of neurons as well as the specific neurochemical interaction among the neurons. It is interesting to note that the structure of clusters of neurons and their specific interconnections may have an effect on one’s ability to learn and an influence on speed of understanding and reaction time to intellectual stimulations.
At birth, our mental faculties are very plastic, that is, its capacity to process and store sensory information is very high. Neuronal connections are usually generated, broken and regenerated, which suggests that early educational and environmental stimulations are essential for the child’s development. This is the critical period of the development of the particular child’s linguistic, cognitive and social abilities. A classical question is actually the infant brain is empty, a tabula rasa, at birth. The Ancient greek philosopher Aristotle (fourth century N. C. E. ) was probably the first to introduce the tabula rasa (blank slate) idea. Based on the tabula rasa theory, an infant’s brain is empty of mental content, which is acquired later with experience and understanding.
