Lateralization is the differing functions of the left and right hemispheres of the brain . Research over the years has shown that damage to one hemisphere or the other can produce different problems and knowing this can help predict behavior.
What is lateralization and why is it important in the way our brain functions?
Researchers studying the human brain have long maintained that the advantage of having a lateralized brain is increased brain capacity , because lateralization means that neural circuits do not have to be duplicated in each hemisphere. Each hemisphere can have its own specialized circuits and functions.
Why is lateralisation important?
Lateralisation of brain function is widespread in vertebrates. ... The advantages accrue not only at individual but also at population level, where lateralisation produces advantages in social cohesion , for example, by being able to relate to others as a potential mate or friend.
What does lateralization mean?
: localization of function or activity on one side of the body in preference to the other .
What is an example of a lateralization?
The best example of an established lateralization is that of Broca’s and Wernicke’s areas , where both are often found exclusively on the left hemisphere. ... Another example is that each hemisphere in the brain tends to represent one side of the body.
Which side of brain is more powerful?
The theory is that people are either left-brained or right-brained, meaning that one side of their brain is dominant. If you’re mostly analytical and methodical in your thinking, you’re said to be left-brained. If you tend to be more creative or artistic, you’re thought to be right-brained.
How does lateralization affect brain?
Delays in lateralization can affect many cognitive and behavioral skills . ... Deficits in right hemisphere language development can lead to difficulties processing nonliteral language, sarcasm, metaphors and reading. Nonverbal social abilities also tend to be affected by brain lateralization.
What are signs of lateralization?
Vegetative symptoms during seizures arising from temporal lobe such as spitting, nausea, vomiting, urinary urge are typical for seizures originating from non-dominant (right) hemisphere. Ictal pallor and cold shivers are dominant hemispheric lateralization signs.
What do split brain patients see?
Another study by Parsons, Gabrieli, Phelps, and Gazzaniga in 1998 demonstrated that split-brain patients may commonly perceive the world differently from the rest of us . Their study suggested that communication between brain hemispheres is necessary for imaging or simulating in your mind the movements of others.
What is the right side of the brain responsible for?
Our brains have two sides, or hemispheres. In most people, language skills are in the left side of the brain. The right side controls attention, memory, reasoning, and problem solving .
What does the lateralization do?
functional specialization of the brain, with some skills, as language, occurring primarily in the left hemisphere and others, as the perception of visual and spatial relationships , occurring primarily in the right hemisphere.
How does brain lateralization affect language?
The closest explanation is that with the brain’s left hemisphere controlling the body’s right side , it is stronger whereas the left hemisphere is more dominant over the right hemisphere because nearly 92% of all humans use the left hemisphere for language.
What is another word for lateralization?

What is it called when you use both sides of your brain?
You may have even heard the term “golden brain ” used to refer to people who use both sides of their brain equally. This is very similar to how most people are either right handed or left handed, and some people are even ambidextrous!
What age does brain lateralization occur?
Activation of left perisylvian structures by speech has been found in infants as young as three months of age (Dehaene-Lambertz et al. 2006), whereas progressively more lateralized responses to speech have been reported to occur later during the first year of life (e.g., Arimitsu et al.
Which of the following is an example of brain lateralization?
Laterality, in biological psychology, the development of specialized functioning in each hemisphere of the brain or in the side of the body which each controls. The most obvious example of laterality is handedness , which is the tendency to use one hand or the other to perform activities.
