The human brain is an amazing tool. It’s one of the organs of the body, and it’s the most complex instruments in the known universe. The other organs such as the heart or the lungs are not as sophisticated. And unlike these more simple organs that are capable of being transplanted from one person to another, the brain is so interwoven into the fabric of our bodies. So we could refer to the body as being an organ of the brain, as opposed to being the other way around. As an adult human’s brain, it’s about the size or weight of a melon is. What makes the brain so remarkable is that it’s made up of 86 billion neurons, interconnected by 1.5 times 10 to the 14 sign apses. These are the junctions between two nerve cells consisting of a minute gap, across which impulses pass by diffusion of a neuro transmitter. There are 4500 neuro transmitters. Most people have heard of two or three such as dopamine and serotonin. But there are many, many more. This arrangement offers unlimited memory. The brain combines language and visual imagery, operating by perception is capable of thinking about itself, which is what you’re doing right now. And it’s capable of working with emotions. The brain is made up of several distinct regions. Each of these regions serves two functions, physiological, and psychological. Each region has a different purpose, but they all connect to give us our feelings, thoughts and actions. Biologically, each region plays a role in managing aspects of our physiology, from regulating oxygen levels in the blood to sending messages to the muscles that enable us to move. Each region possesses a distinct psychological function for the way in which it processes information. When considering the psychological function of the human brain, is possible to divide it into the following areas. The primitive brain or the reptilian brain controls functions basic to survival, such as heart rate, breathing, digesting food, and sleeping. It’s the lowest most primitive area of the human brain, and it includes the cerebellum, which is involved in coordinating movement. Although we’re not consciously aware of the information processed by our lower brain, it receives information from the senses, and provides us with our instincts or our gut feelings. The term the emotional brain is used to describe the collective areas that make up the limbic system. And this includes the amygdala. These are the brain structures that filter and process emotions, and emotional responses. This region is important because it plays a lead role in governing emotions and our natural and automatic behaviors and functions. The outer cortex forms the rest of the brain. The rational brain is made up of the frontal lobes or prefrontal cortex, as this region is more precisely known. This area of the brain enables us to reason to be rational and to be objective, and to master our instincts and our emotions. The left hemisphere of the cortex is where we store the rules by which we live our lives. For example, the rules of language is stored in this area of the brain, which is why people who suffer from strokes within the left hemisphere often find speaking difficult. Being more structured and rule based, the left hemisphere processes information sequentially, with each step being a consequence of the previous one. The right hemisphere of the color text, in stark contrast, deals with pattern making. It deals with ambiguity and new learning. The right hemisphere therefore, processes information in a more irrational style by looking at the linkages, patterns, and associations with other memories in stored experiences. The brain is capable of multitasking, using both hemispheres simultaneously, is able to process information very quickly and intuitively. And it’s able to adapt to circumstances when needed. However, it’s not perfect. The brain is limited to some degree. It makes mistakes without care, and it’s influenced by outside sources. to work effectively, the human brain consumes vast amounts of glucose energy. It consumes about 20% of the body’s energy. So, if it doesn’t have to work hard, it won’t. This means that it wants to make the quickest decisions possible, and will often jump to conclusions, make snap decisions and judgments without all the information available. So belief in your brain giving you an accurate representation of reality, and a deeper understanding of circumstances can often get you into trouble.
