BLUE                    BRAIN

What is Virtual Brain

We can say Virtual brain is an artificial brain, which does not actually the natural brain, but can act as the brain .It can think like brain, take decisions based on the past experience, and response as the natural brain can. It is possible by using a super computer, with a huge amount of storage capacity, processing power and an interface between the human brain and this artificial one .Through this interface the data stored in the natural brain can be up loaded into the computer .So the brain and the knowledge, intelligence of anyone can be kept and used for ever, even after the death of the person.

 Need of Blue Brain:

Now the world is very much developed because of the intelligence we have which is an inborn quality and cannot be made. Few people in the world have such quality and because of it, they can think up to a level or standard which others cannot do. There is a necessity of such an intelligence and intelligent brain to the human society but the intelligence gets lost after the death of the body and virtual brain is the solution for all these.

Everyone is busy in their lives that they have the difficulty in remembering the events like historical facts, important dates and much more. Availing a machine called the virtual brain is a complete solution for all these issues and relaxes the people without any burden.

How is it Possible?

Raymond Kurzweil recently furnished a paper on this in which he explains both the invasive and non-invasive techniques. The most assuring technique is the use of tiny robots or nano robots as they are small enough to travel the human circulatory system. By moving into the spine and brain the robots will be able to monitor the activities of the central nervous system. The required thing is the computer with huge storage space and processing power.

Possibility

Many people believe firmly those we possess a soul, while some very technical people believe that quantum forces contribute to our awareness. But we have to now think technically. Really this concept appears to be very difficult and complex. First, it is helpful to describe the basic manners in which a person may be uploaded into a computer. Raymond Kurzweil recently provided an interesting paper on this topic. In it, he describes both invasive and non-invasive techniques. The most promising is the use of very small robots, or Nanobot. These robots will be small enough to travel throughout our circulatory systems. Traveling into the spine and brain, they will be able to monitor the activity and structure of our central nervous system. They will be able to provide an interface with computers that is as close as our mind can be while we still reside in our biological form. Nanobot could also carefully scan the structure of our brain, providing a complete readout of the connections between each neuron. They would also record the current state of the brain. This information, when entered into a computer, could then continue to function like us. All that is required is a computer with large enough storage space and processing power.

Natural Brain

The brain essentially serves as the body’s information processing center. It receives Signals from sensory neurons (nerve cell bodies and their axons and dendrites) in the central and peripheral nervous system, and in response it generates and sends new signals that instruct the corresponding parts of the body to move or react in some way. It also integrates signals received with signals from adjacent areas of the brain, giving rise perception and consciousness. The brain weighs about 1500 grams (3 pounds) and constitutes about 2% of total body weight. It consists of three major divisions: - The massive paired hemispheres of the cerebrum. - The brainstem, consisting of the thalamus, hypothalamus, epithalamus, subthalamus , Midbrain, pons and medulla oblongata. - The cerebellum.

 Functioning Of Natural Human Brain

The human ability to feel, interpret and even see is controlled, in computer like calculations, by the magical nervous system. The nervous system is quite like magic because we can’t see it, but its working through electric impulses through the body. One of the world’s most "intricately organized" electron mechanisms is the nervous system. Not even engineers have come close for making circuit boards and computers as delicate and precise as the nervous system.

 The three simple functions that it puts into action: sensory input, integration, motor output.

 Sensory input

 When our eyes see something or our hands touch a warm surface, the sensory cells, also known as neurons, send a message straight to your brain. This action of getting information from your surrounding environment is called sensory input because we are putting things in your brain by way of your senses. 

Integration

 Integration is best known as the interpretation of things we have felt, tasted, and touched with Our sensory cells, also known as neurons, into responses that the body recognizes. This process is all accomplished in the brain where many neurons work together to understand the environment. 

 Motor Output

 Once our brain has interpreted all that we have learned, either by touching, tasting, or using any other sense, then our brain sends a message through neurons to effecter cells, muscle or gland cells, which actually work to perform our requests and act upon the environment.

 Advantages And Disadvantages

Advantages

1. We can remember things without any effort.

2. Decision can be made without the presence of a person.

 3. Even after the death of a man his intelligence can be used.

4. The activity of different animals can be understood. That means by interpretation of the electric impulses from the brain of the animals, their thinking can be understood easily.

5. It would allow the deaf to hear via direct nerve stimulation, and also be helpful for manypsychological diseases. By down loading the contents of the brain that was uploaded into thecomputer, the man can get rid from the mad ness.

 Disadvantages:

Further, there are many new dangers these technologies will open. We will be susceptible to new forms of harm.

 1. We become dependent upon the computer systems.

2. Others may use technical knowledge against us

. 3. Computer viruses will pose an increasingly critical threat.

 4. The real threat, however, is the fear that people will have of new technologies. That fear may culminate in a large resistance. Clear evidence of this type of fear is found today with respect to human cloning.Information
