HEMISPHERES OF THE BRAIN MANUAL

Steirs said.ДЇor instance, individuals who have had a stroke on the left side of their brain tend to have trouble with verbal expression through language or understanding what other people are saying to them, he said. The biggest extremes in right or left brain function can be seen in people who have had some sort of brain injury, Dr.

People who are most successful have incorporated both sides of their brain and can switch back and forth.вЂќ

вЂњLike the accountant who is so focused on the details of adding up all of the numbers, but doesnвЂ™t look up to see that the building is on fire. вЂњYou hear all kinds of stereotypes and extremes about people who are left-side dominant or right-side dominant,вЂќ he said. Though people tend to be left- or right-brain dominant, everyone uses both sides of the brain, said Dr. вЂњThey may be better at reading body language and facial expressions, but they may miss the details.вЂќ вЂњThey tend to focus more on the big picture and see connections between different ideas and see how visual and special patterns fit together,вЂќ he said. Right-brain dominant individuals may gravitate to fields that require them to connect ideas and objects, such as writers, sculptors and mathematical theorists, said Dr. вЂњThey may have trouble seeing the big picture.вЂќ вЂњThey tend to be more detail focused, analytical and quick to handle the individual elements in front of them,вЂќ he said. The person who is left-brain dominant will probably find it is easier to follow directions in sequential units, while the right-brain dominant individual will most likely want to use the map, he said.Д«rain hemisphere dominance can also direct people to specific career paths.ДЇor example, engineers, accountants, proofreaders and computer programmers are most often left-brain dominant, because the work tends to be detail oriented, said Dr. вЂњBoth ways can get you to my house, but these are different types of processes in how you accomplish the goal.вЂќ вЂњIf you are coming to my house, I can give you directions in sequential units, or I can give you directions by drawing you a map so you can capture it as a whole,вЂќ Dr.

The right hemisphere deals with simultaneous information, like visualizing a map. вЂњBut, in a small minority of people, those functions are switched.вЂќДЇor the majority of humans, the left hemisphere of the brain controls sequential matters, such as language, words and handling details. вЂњIn most people, certain functions come from the right side and some come from the left,вЂќ he said. However, not as definite is which hemisphere controls particular characteristics, such as artistic or mathematic qualities, Dr. William Steirs, a psychologist with Johns Hopkins Physical Medicine & Rehabilitation at Good Samaritan Hospital in Baltimore. What is true for all people is the left hemisphere of the brain controls the right side the body, and the right hemisphere of the brain controls the left side of the body, said Dr. The intricate gray matter that makes up the human brain lays the foundation of critical thinking, but itвЂ™s the right and left hemispheres that provide most people with the determining factors in their individual strengths and weaknesses.

Recent brain imaging studies have shown no differences between males and females in terms of their brain lateralization. The right side is more interested in attending to the external world. The left side of the brain is more involved with attention to the internal world. The two brain hemispheres also differ in what they pay attention to. Some babies prefer to suck their left or right thumb from as early as 15 weeks. Handedness is inbuilt, and it can even be detected while the baby is in the womb. For example, a left-handed person uses their right brain for manual tasks and vice versa. Left- and right-handed people use the left and right brain differently. People who are deaf show speech-like brain activity when watching sign language. Visually based languages are also the domain of the left brain. In most people, the two main language areas, known as BrocaвЂ™s area and WernickeвЂ™s area, are found in the left hemisphere. The left brain is more active in speech production than the right. Emotions are expressed and recognized in others by the right brain. This is the domain of the right brain, in both humans and also in non-human primates. Functions and characteristics of each hemisphereДЄlthough people do not fall neatly into the categories of left-brained or right-brained, there are some differences in what the left and right hemispheres do.Дifferences in the left and right brain hemisphere function exist in:
