In this article we are going to investigate the similarities between the human nervous system(especially the brain part) and the computer. If are unfamiliar with the basic digital theory you can skip this article, but it is important for some aspects of our discussion because there are too many such similarities, including the "bugs" inherent in the computer.
How the both systems operate with the information?
|Computer system||Nervous system|
|Decomposition of the ordinary(decimal) number to
binary numbers, because the wires have too tight frequency bandwidth.
For example 56(decimal)=00111000(8 bit binary). It is easy to transmit the digital number if we have eight wires and using the "on"/"off" notation. More clear - we can use 8 wires to transmit the binary number - the first wire - no voltage(representing "off"[zero]), the second wire - no voltage, the third wire must be "1", so we supply some voltage (for example 5Volts, which is standard for the TTL digital components), the 4th wire must be "1" again and so on....
The digital representation of the numbers is useful because the electronics components can deal with the "on/off" notation. It also useful because of the perfect fit of the "boolean algebra" that actually bases the digital logic and computations.
|From the nervous system's side it's almost the
same - the receptors decompose the information(for eample the human ear from the receptors article) and then transmit the
information via separated nerves to the brain. The differnce is that the nervous system is
not limited in 8bits or 16bits communicational channels which could be not enough or too
much. The nervous system uses just enough bits in order to send the information somewhere.
Another difference is that through the nerves the streaming information is not so digital. The signal for pain for example could be stronger or liter depending on the intesity of the pain - so the nervous impulse gets higher voltage. The brain then receives higher voltage and responds in accrodance with the pain intesity.
The real and the virual environment

|The computer "hehaviour" depends on
the software running on it. It can process text, creating 3d simulations or just
calculating 1+1 one billion times. There are many people who are creating the so called
"Artifical Intelligence"(or just AI) software that simulates some similar to the
live organisms environments(see our intellect
simulator). The computer's environment could be programmed easily, also you can extend
the behaviour by the software - by programming responses to some environment.
A good example of this are the "reaper bots" used in the computer games for simulating a human oponent - the environment is the actual stage of the game and it is a software code. The bots are also a software code that tries to kill you using some AI algorithms. Such AI algorithm could be just telling the computer(in a computer language of course) "Walk randomly around until you see the human, then start strafing in a circle around the human shooting at him. If this doesn't help and you remain with 10% health status - escape."
|The human behaviour depends on the complex environment. The intellect is not a part
of the environment, but of the brain. Just like we force the computer to run the bots and
the environment as two separated things. The bots are the intellect and the environment is
the virtual stage. A difference between the two conectps is that the human behaviour
doesn't depend only on the physical environment, but also on the social environment. It's
pretty impossible for now to simulate a social environment in the computer.
In spite of this many elaborations are made that try to simulate some relations between lower organisms(and nervous system) - insects.
A very common hacking technique in the computer systems is the "buffer overflow". It is applicapable when there is some place in the memory where the user should enter some data, and the place reserved is for example 1024 bytes. If the user enters 1025 bytes he overwrites the one bit of the memory that could cause executing some other program. The same is about the principle of the brainwashing and the light and sound machines - they work by giving an unexpected data to the thinking engine of the brain. They both overwrite the current beliefs, opinions, feeling by giving an unexpected data to the thinking engine of the brain (brainwashing uses one vulnerable belief to access the brain, the light a sound machines use receptors to execute the new brainwaves frequency).
In order to perform its operations the computer uses digital logic devices(semiconductor chips concsisting of many transistor units). The nervous system analog are the brainparts with their interconnected neurons. Although the physics around these two thing are different the sheme is the same.
