Your brain is an amazing organ.0:22
Weighing about 3 pounds , it not only controls your other organs, regulates pleasure and pain, hunger and thirst, blood pressure and body temperature, but it also plays a huge role in determining your personal identity through thoughts, memories, and0:32
Although a brain is often compared to the central processing unit in a laptop, in reality, the brain is far superior and far more complex.0:49
Underneath a protective skull, the brain appears to be separated into two halves: the left hemisphere and the right hemisphere.0:58
But this is not quite true.1:06
Information and instructions pass from one side of the brain to the other through the corpus callosum, about 200 to 250 million nerve fibers.1:08
Surprisingly, each hemisphere is responsible for the opposite side of the body.1:18
For example, information received from our senses on one side of the body is communicated to the opposite hemisphere of the brain.1:23
Some scientists think that the two hemispheres control different abilities and behavior.1:31
The left side has more connection with logic and analysis.1:36
It deals with details.1:39
The right is usually considered more creative and imaginative.1:42
It prefers general ideas or the big picture and deals with emotions.1:46
For artists such as writers, sculptors, and musicians, the right side of their brain is dominant.1:51
On the other hand, professions that require organization and facts, like scientists and accountants, often have a preference for the left side.1:57
It seems that each hemisphere of the brain has a tendency for certain kinds of function.2:06
For example, the left side of the brain may handle the syntax and vocabulary of language, but the right side controls the accent, speed, and intonation of speech.2:11
Neurologists have found that if one side of the brain is removed, The other side can take over some of its roles, such as speech, by creating new connections or pathways between brain cells .2:21
However much we may study the human brain, it is probably capable of much more than we will ever know.2:33
