Brain – The Miraculous Organ

The human brain in the most complex and miraculous organ in our body. For many years, scientists and philosophers felt that the heart was the organ which brought us consciousness and thought. But some time back, researchers realized that the brain is what brings us conscience thought and out ability to discriminate. Let’s discuss more about this incredible organ and how it is involved with virtually every other part of our bodies.

The brain is encased and protected within the skull. It is also the center of the nervous system and signals from the brain get transmitted to the specific part of the body it is intended to control.

And though our brain is similar in structure to other mammals, it can actually be about three times larger than the brain of a mammal which is similar in size to us. This plays a key role in why our brain can do so much and provide us with the ability to think and discriminate.

What makes the human brain unique in comparison to other brains is also the fact that our frontal lobes are much larger than anything else in comparison. It is believed that this area of the brain is responsible for functions like planning, reasoning, abstract thought and control. The occipital lobe of our brain is also much larger than other brains. This area is believed to be associated with vision.

The brain communicates through an intricate network of cells which transmit electrical signals. It is estimated that there are over 100 billion neurons in the brain which do not transmit electrical signals and a similar number of cells which do. This equates to more than 1000 trillion synaptic connections.

Not only does the brain control essential functions in our body like respiration, heart rate, kidney functions, and many others but it receives input from these organs and from the outside world and makes adjustments to these organs so they can best adapt and respond to differing stimuli and conditions. It does this process at an incredible rate.

And despite the incredible advances in computer technology, there is not yet a single computer in the world which can match the processing power and speed of the human brain. More importantly nothing has been developed which can discriminate and make decisions based on outside input like the human brain.

For all of its power and functionality, the human brain is very sensitive and must be protected from a variety of threats from the outside world. As indicated earlier the brain is encased and protected by our skull. It also floats in a viscous fluid which helps to protect the brain from shock and infection.

But despite injury prevention, there are a number of diseases which can affect the brain. This includes diseases like Alzheimer’s disease, Parkinson’s disease and others.

There are many treatments being developed to help to prevent or slow the progression of these diseases. As research continues it is hoped that effective treatments can be developed to cure these ravaging diseases and keep the brain functioning at optimum efficiency.
