The lateralization of brain function (or hemispheric dominance [1] [2] / lateralization [3] [4]) is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other.
Lateralization of function and asymmetry in the human brain continues to propel a popular branch of neuroscientific and psychological inquiry. Technological advancements for brain mapping have enabled researchers to see more parts of the brain more clearly, which has illuminated previously undetected lateralization differences that occur during ...
Emotional lateralization is the asymmetrical representation of emotional control and processing in the brain. There is evidence for the lateralization of other brain functions as well. Emotions are complex and involve a variety of physical and cognitive responses, many of which are not well understood.
It has been shown that cerebral lateralization is a widespread phenomenon in the animal kingdom. [7] Functional and structural differences between left and right brain hemispheres can be found in many other vertebrates and also in invertebrates.
Lateralization may differ between the sexes, with men often being said to have a more lateralized brain. This is often attributed to differences in "left-" and "right-" brained abilities. One factor that contributes support to the idea that there is a sex difference in brain lateralization is that men are more likely to be left-handed.
The Geschwind–Galaburda hypothesis has garnered empirical support from a number of studies. For instance, Witelson et al. discovered that Einstein’s brain exhibited an atypical pattern of cerebral lateralisation, which supports the hypothesis that brain lateralisation is related to cognitive abilities.

Dichotic listening is a psychological test commonly used to investigate selective attention and the lateralization of brain function within the auditory system.It is used within the fields of cognitive psychology and neuroscience.
In a review, it was associated to the "impulsive behaviour", handedness, mostly left and/or crossed lateralities, and above of all, the eyedness or eye-laterality as a key to detect and to relate brain lateralization which that behavioural disorder when it is crossed-eye-hand laterality [23] which has also been related in a work, reporting a ...
