An analysis of the human bran versus the computer in the history of technology

Computer Differentiating a human and a computer is easy. There is really no confusion between the two unless the time comes when cyborgs, or half human half machines will roam the earth. Nowadays, the definitions of both terms are concretely described by many sources. Foremost, both computers and humans use electricity.

Alex Mit Shutterstock The human brain is the command center for the human nervous system. It receives input from the sensory organs and sends output to the muscles.

The human brain has the same basic structure as other mammal brains, but is larger in relation to body size than any other brains. Facts about the human brain The human brain is the largest brain of all vertebrates relative to body size It weighs about 3. Underneath lies the brainstem, and behind that sits the cerebellum.

The outermost layer of the cerebrum is the cerebral cortex, which consists of four lobes: Each of these contains fluid-filled cavities called ventricles. The forebrain develops into the cerebrum and underlying structures; the midbrain becomes part of the brainstem; and the hindbrain gives rise to regions of the brainstem and the cerebellum.

The cerebral cortex is greatly enlarged in human brains, and is considered the seat of complex thought. Visual processing takes place in the occipital lobe, near the back of the skull. The temporal lobe processes sound and language, and includes the hippocampus and amygdala, which play roles in memory and emotion, respectively.

The parietal lobe integrates input from different senses and is important for spatial orientation and navigation. The primary functions of the brainstem include: Between the cerebrum and brainstem lie the thalamus and hypothalamus.

The thalamus relays sensory and motor signals to the cortex and is involved in regulating consciousness, sleep and alertness. The cerebellum lies beneath the cerebrum and has important functions in motor control.

It plays a role in coordination and balance, and may also have some cognitive functions. Other intelligent animals, such as monkeys and dolphins, also have these folds in their cortex, whereas mice have smooth brains, he said.

Humans also have the largest frontal lobes of any animal, Holland said. The frontal lobes are associated with higher-level functions such as self-control, planning, logic and abstract thought — basically, "the things that make us particularly human," he said.

A diagram of a cross-section of the human brain. The hemispheres are strongly, though not entirely, symmetrical. The left brain controls all the muscles on the right-hand side of the body; and the right brain controls the left side. One hemisphere may be slightly dominant, as with left- or right-handedness.

The popular notions about "left brain" and "right brain" qualities are generalizations that are not well supported by evidence. Still, there are some important differences between these areas.

The right brain plays a role in visual and auditory processing, spatial skills and artistic ability — more instinctive or creative things, Holland said — though these functions involve both hemispheres. Scientists hope the increased understanding will lead to new ways to treat, cure and prevent brain disorders.

When the project was announced, President Obama convened a commision to evaluate the ethical issues involved in research on the brain. In Maythe commission released the first half of its reportcalling for ethics to be integrated early and explicitly in neuroscience research.

In Marchthe commission released the second half of the reportwhich focused on issues of cognitive enhancement, informed consent and neuroscience and the legal system. Some researchers question what the initiative will achieve.As the admin of this web site is working, no uncertainty very quickly it will be well-known, due to its feature contents.

contribute to 50% of the human caloric intake; rice comprises 23%, wheat 17%, and corn 10% of the calories consumed [1]. Rice is primarily used for human consumption, whereas a larger proportion of wheat and corn are used as animal feed.

On average, per capita rice consumption is kg per year. The computer is not so precise in its ability to interface. OK, sometimes the brain may interpret the stimuli on its own. Story One: Last century, we built cyborgs — not man-machine things but animal-machine things — for the purpose of vapor detection.
