Its complexity is as a result of direct consequence of the natural and biological evolution that plays a significant role in the morphological structure and divisions.
What does the research say? Research into left brain vs. Recent research suggests that the left brain vs. They measured the activity of the left and right hemispheres, using an MRI scanner.
Their results show that a person uses both hemispheres of their brain and that there does not seem to be a dominant side. For example, a study in PLoS Biology says that the language centers in the brain are in the left hemisphere, while the right hemisphere is specialized for emotion and nonverbal communication.
Sperry the Nobel Prize in However, popular cultural exaggeration of these findings led to the development of beliefs of left brain and right brain personalities.
Functions and characteristics of each hemisphere Although 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.
Differences in the left and right brain hemisphere function exist in: Emotion This is the domain of the right brain, in both humans and also in non-human primates. Emotions are expressed and recognized in others by the right brain.
Language The left brain is more active in speech production than the right. Sign language Visually based languages are also the domain of the left brain.
People who are deaf show speech-like brain activity when watching sign language. Handedness Left- and right-handed people use the left and right brain differently. For example, a left-handed person uses their right brain for manual tasks and vice versa. Handedness is inbuilt, and it can even be detected while the baby is in the womb.
Some babies prefer to suck their left or right thumb from as early as 15 weeks. Attention The two brain hemispheres also differ in what they pay attention to. The left side of the brain is more involved with attention to the internal world.
The right side is more interested in attending to the external world. Recent brain imaging studies have shown no differences between males and females in terms of their brain lateralization. Does hemispheric dominance differ between people? Hemispheric dominance may differ between people, although this area requires more research.
The side of the brain used in each activity is not the same for every person. The side of the brain that gets used for certain activities may be influenced by whether a person is left- or right-handed.
A study notes that up to 99 percent of right-handed individuals have the language centers in the left of the brain. But so do about 70 percent of left-handed individuals.
Hemispheric dominance varies from person to person and with different activities. More research is needed for science to fully understand all of the factors that affect this. Takeaway The theory that a person is either left-brained or right-brained is not supported by scientific research.
Some people may find the theory does align with their aptitudes. However, they should not rely on it as a scientifically accurate way to understand the brain. The left brain vs.The left brain vs. right brain personality belief may have lasted for so long because, in reality, brain activity is not symmetrical, and it does vary from person to person.
