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 cortex , that is supported by an inner layer of white matter.

The brain is an amazing three-pound organ that controls all functions of the body, interprets information from the outside world, and embodies the essence of the mind and soul. Intelligence, creativity, emotion, and memory are a few of the many things governed by the brain. Protected within the skull, the brain is composed of the cerebrum, cerebellum, and brainstem.

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 cortex , that is supported by an inner layer of white matter. In eutherian placental mammals, the hemispheres are linked by the corpus callosum , a very large bundle of nerve fibers. Smaller commissures, including the anterior commissure , the posterior commissure and the fornix , also join the hemispheres and these are also present in other vertebrates. These commissures transfer information between the two hemispheres to coordinate localized functions. There are three known poles of the cerebral hemispheres: the occipital pole , the frontal pole , and the temporal pole.

The problem is reviewed of sex differences and the brain organization of the visual-spatial and verbal-cognitive functions both in adults and in the 5—year old children. Characteristic of men are the integral strategy of the face image recognition, specialization of the right hemisphere for visual-spatial functions, and the tonic inhibitory effect of the right hemisphere on the left one. Typical of women are the fragmented type of the image recognition, the equality of the brain hemispheres functions at the unfamiliar face recognition, and predominance of the left hemisphere by accuracy of the object localization in the visual field. It is possible that the general strategy of the recognition in women is not realized due to the right hemisphere submitted to the interfering effect of the left hemisphere. Analysis of sex differences in distribution of verbal functions shows that the capability for the verbal learning at the age of 5 years and older is higher in girls than in boys. Such capability seems to be accounted for by the superiority of the left hemisphere in girls in this type of its activity and by its earlier development and maturation. The phenomenon of semantic paralexia appearing more often in boys is accounted for by inclusion of lexical-semantic fields of the right hemisphere symmetric areas in the verbal-cognitive activity There are reasons to believe that the higher capability in girls for the verbal learning is mainly due to processes of the auditory-verbal integration within the limits of the left hemisphere, whereas this verbal ability in boys depends on the relative predominance of the interhemispheric connections.

In the folklore of the Middle East, the story is told about a man named Nasrudin, who was searching for something on the ground. So, the friend went down on his knees, too, and they both looked for it. After […]. But let me leave the story momentarily while I pose some questions—also simple yet mysterious—that have always puzzled me. What I plan to do in this article is weave together some tentative answers to these three questions with the story of Nasrudin around a central theme, namely, that of the specialization of the hemispheres of the human brain and what that specialization means for management. Let us first try to answer the three questions by looking at what is known about the hemispheres of the brain.

Бринкерхофф опрокинул директорский стул и бросился к двери. Он сразу же узнал этот голос. - Директор! - воскликнул он и, подойдя к Фонтейну, протянул руку.  - С возвращением, сэр. Вошедший не обратил на его руку никакого внимания.

Planning on the Left Side and Managing on the Right

Хейл сердито посмотрел на обезумевшего сотрудника лаборатории систем безопасности и обратился к Сьюзан: - Я сейчас вернусь. Выпей воды. Ты очень бледна.

 - Нашим главным стражем была система Сквозь строй, а Стратмор вышвырнул ее в мусорную корзину. - Это объявление войны, - прошептал Фонтейн срывающимся голосом. Джабба покачал головой: - Лично я сомневаюсь, что Танкадо собирался зайти так. Я думаю, он собирался оставаться поблизости и вовремя все это остановить. Глядя на экран, Фонтейн увидел, как полностью исчезла первая из пяти защитных стен.

Глядя, как он шелестит деньгами, Меган вскрикнула и изменилась в лице, по-видимому ложно истолковав его намерения. Она испуганно посмотрела на вращающуюся дверь… как бы прикидывая расстояние. До выхода было метров тридцать.

    The purpose of the study was to (1) compare the performance on left and right hemisphere processing tasks of male and female kindergarten.

    The lateralization of brain function is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other.
