 The brain is the command center for the entire body. It receives information from our senses and controls our thoughts and movement. It is divided into 3 parts: the cerebrum (1), which is the largest part, consists of 2 hemispheres. The outer layer is known as the cortex (1/8 inch thick) and contains millions of cells with fibers that send messages to other brain areas. It is divided into 4 regions: The frontal lobe controls our emotions, higher thinking skills such as problem solving and controlling movement.

It continues to develop until the mid-20s. The temporal lobe helps process hearing and other senses and helps with language and reading. The parietal lobe is involved with our senses, attention and language. The occipital lobe helps us see and recognize colors and shapes. The cerebellum (2) plays a key role in motor control coordination and spatial navigation and controls our motion, balance and ability to learn new things. The medulla or brain stem(3), which connects the brain to the spinal cord(a nerve path which runs all the way down the back, sending and receiving information from the senses controlling our involuntary actions such as vision, hearing, eye movement, and body movement(midbrain), digestion, heart beat(medulla oblongata) and breathing(pons) and other body reflexes( vomiting, coughing, sneezing, swallowing). ·         Cerebrum: sensing, think, imagine·         Cerebellum: motion, balance, learning new things, muscle movement, control·         Medulla: automatic actions in body, breathing, digestionThe brain controls many actions through nerve impulses, but there are also some body functions that the brain modulates over many hours or days by secreting hormones via special glands like the hypothalamus(gives the adrenaline flowing), the pituitary gland(controls growth, body temperature, pregnancy and child birth) and the pineal gland(controls sleep and circadian rhythms).

  Computers have certain primary purposes: Entering data, manipulating data, viewing processed data and storing data. They are designed to transform raw data into information. The computer operates under the control of instructions stored in its own memory unit and can accept input data, process it arithmetically and through sequenced based logic, produce information and store the results for future use.( times, the human brain presents similar functions to a computer since, both are used for storage, processing information and execute tasks.

Both work with electrical signals, in a computer the binary system is used and in the human brain through neuron to neuron. Both the brain and the computer use electricity to send signals. As it concerns the memory, computers can continue to store memories as they add more RAM and stores them in a more orderly way than the human brain.

However, computers can only follow instructions and patterns made by a programmer, while the brain behaves freely, using reasoning and common sense. Also, the brain can’t act without emotions while computers only act under the logic. Moreover, the human brain can easily adapt to new circumstances and learn faster. Complex computer processes can be achieved by a few hundred neuron transmissions, requiring much less energy and performing at a greater efficiency. One of the things that truly makes the brain stand out is the flexibility that it displays.

?he human brain has the ability to rewire itself (neuroplasticity). Neurons have the ability to disconnect and reconnect with others, and even change their basic features, something that even a carefully constructed computer can’t do. Apart from that, computers are machines that are based on logic, reproducibility, predictability, and math. The human brain, on the other hand, is a tangled amount of neurons that don’t behave in a predictable manner. ( fastest supercomputers created, which are massive, haven’t even reached the 50 pet FLOP mark, which is still 20 times slower than the human brain’s processing speed.

Looking towards the future, experts believe that only exascale computing could be possible by 2020-2025.In conclusion, so far the human brain is far more advanced and efficient than the most impressive supercomputers ever made, since it possesses more raw computational power.
