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. The median longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum.
The Herrmann Brain Dominance Instrument (HBDI) is a system to measure and describe thinking preferences in people, developed by William "Ned" Herrmann while leading management education at General Electric 's Crotonville facility. It is a type of cognitive style measurement and model, and is often compared to psychological pseudoscientific ...
Neuroanatomy of handedness. An estimated 90% of the world's human population consider themselves to be right-handed. [1] The human brain's control of motor function is a mirror image in terms of connectivity; the left hemisphere controls the right hand and vice versa. This theoretically means that the hemisphere contralateral to the dominant ...
Cerebral hemisphere. Human brain seen from front. The vertebrate cerebrum (brain) is formed by two cerebral hemispheres that are separated by a groove, the longitudinal fissure. The brain can thus be described as being divided into left and right cerebral hemispheres. Each of these hemispheres has an outer layer of grey matter, the cerebral ...
The reasons for this are not fully understood, but it is thought that because the left cerebral hemisphere of the brain controls the right side of the body, the right side is generally stronger; it is suggested that the left cerebral hemisphere is dominant over the right in most humans because in 90-92% of all humans, the left hemisphere is the ...
Left hands make up over 90% of the artwork, demonstrating the prevalence of right-handedness. [1] A female student writes with her left hand. In human biology, handedness is an individual's preferential use of one hand, known as the dominant hand, due to it being stronger, faster or more dextrous. The other hand, comparatively often the weaker ...
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. The general purpose of emotions is to ...
The Geschwind–Galaburda hypothesis is a neurological theory proposed by Norman Geschwind and Albert Galaburda in 1987. [1] The hypothesis posits there are sex differences in cognitive abilities by relating them to lateralisation of brain function. [1] The maturation rates of cerebral hemispheres differ and are mediated by circuiting ...
