Lateralization of cortical functioning refers to the division of labor between both cerebral hemispheres for almost all brain activity. Each hemisphere has abilities not completely shared by its partner. In most people, the left hemisphere has greater control over language, thus giving them left cerebral dominance.

What is cortical functioning?
Cortical functions are well-defined for primary cortical areas like motor, sensory and visual functions. Recent data from functional imaging indicate that large and diverse areas of the cerebral cortex are involved in planning motor tasks or coding (memory).
What do you understand by lateralization of the brain?
The term brain lateralization refers to the fact that the two halves of the human brain are not exactly alike. Each hemisphere has functional specializations: some function whose neural mechanisms are localized primarily in one half of the brain.
What is an example of 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.
What is lateralization and why is it important?
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 higher cortical functioning?
The higher cortical functions include language, vision, recognizing objects in space (visuospatial recognition), and awareness. The three characteristics of all higher-order functions are as follows: • The cerebral cortex must be involved—complex interactions occur within the cortex and between it and other brain areas.
What does cortical mean?
1: of, relating to, or consisting of cortex. 2: involving or resulting from the action or condition of the cerebral cortex.
What are the functions that lateralization is responsible for?
Lateralization of brain function is the view that functions are performed by distinct regions of the brain. For instance, it is believed that there are different areas of the brain that are responsible for controlling language, formulating memories, and making movements.
Why is it important to consider lateralization?
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.
What is true lateralization?
Lateralization develops with age and is not already developed at birth. Left-handed people usually exhibit a wider frontal, parietal, and occipital lobe on the left compared to the same lobes on the right. Imagination, insight, and artistic skill are usually specialties of the right hemisphere.
What is lateralization also called?
(In scientific literature, the terms lateralization, hemisphere specialization and asymmetry hemispheric differences are used interchangeably.)
Do humans contribute to lateralization?
For a long time, lateralization was considered unique to humans, but recently it has become clear that lateralization is a fundamental characteristic of the organization of brain and behaviour in vertebrates (Vallortigara & Rogers 2005).
What is lateralization quizlet?
Lateralization refers to the localization of a function in one hemisphere or the other.
Why do researchers believe that the brain exhibits some level of hemispheric specialization?
In addition to providing two distinct manners of analyzing information within one brain, the relative specialization of the hemispheres allows them to act as distinct processors. When task demands are high, the brain’s processing capacity can be increased by interaction between these two processors.
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.
What is lateralization in psychology quizlet?
Lateralization. The specialization of the right and left cerebral hemispheres for particular functions.
