Human Brain: Facts, Functions & Anatomy

NCBI Bookshelf. Outside the specialized world of neuroanatomy and for most of the uses of daily life, the brain is more or less an abstract entity. We do not experience our brain as an assembly of physical structures nor would we wish to, perhaps ; if we envision it at all, we are likely to see it as a large, rounded walnut, grayish in color. This schematic image refers mainly to the cerebral cortex, the outermost layer that overlies most of the other brain structures like a fantastically wrinkled tissue wrapped around an orange. The preponderance of the cerebral cortex which, with its supporting structures, makes up approximately 80 percent of the brain's total volume is actually a recent development in the course of evolution.

The cerebrum is the largest part of the brain. The two hemispheres are separated by a groove called the interhemispheric fissure. Each hemisphere of the cerebrum is divided into broad regions called lobes. Each lobe is associated with different functions:.

The human brain is the command center for the human nervous system. It receives signals from the body's sensory organs and outputs information to the muscles. The human brain has the same basic structure as other mammal brains but is larger in relation to body size than any other brains. The largest part of the human brain is the cerebrum, which is divided into two hemispheres, according to the Mayfield Clinic. Underneath lies the brainstem, and behind that sits the cerebellum.

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 brain receives information through our five senses: sight, smell, touch, taste, and hearing - often many at one time. It assembles the messages in a way that has meaning for us, and can store that information in our memory.

The cerebrum or telencephalon is the largest part of the brain containing the cerebral cortex of the two cerebral hemispheres , as well as several subcortical structures, including the hippocampus , basal ganglia , and olfactory bulb. In the human brain , the cerebrum is the uppermost region of the central nervous system. The cerebrum develops prenatally from the forebrain prosencephalon. In mammals, the dorsal telencephalon, or pallium , develops into the cerebral cortex , and the ventral telencephalon, or subpallium , becomes the basal ganglia. The cerebrum is also divided into approximately symmetric left and right cerebral hemispheres.

Камера последовала за Халохотом, двинувшимся в направлении жертвы. Внезапно откуда-то появился пожилой человек, подбежал к Танкадо и опустился возле него на колени. Халохот замедлил шаги. Мгновение спустя появились еще двое - тучный мужчина и рыжеволосая женщина. Они также подошли к Танкадо.

Не обращая внимания на устремленные на него любопытные взгляды десятков пар глаз, Беккер шагнул в толпу. Он ослабил узел галстука и рухнул на стул у ближайшего свободного столика. Казалось, что с той минуты, когда рано утром ему позвонил Стратмор, прошла целая вечность. Сдвинув в сторону пустые пивные бутылки, Беккер устало опустил голову на руки. Мне нужно передохнуть хотя бы несколько минут, - подумал .

Серые глаза светились уверенностью, с которой сочеталась профессиональная скрытность, но сегодня в них проглядывали беспокойство и нерешительность. - У вас испуганный вид, - сказала Сьюзан. - Настали не лучшие времена, - вздохнул Стратмор. Не сомневаюсь, - подумала. Сьюзан никогда еще не видела шефа столь подавленным.

Я так испугалась, увидев. - Не стоит, - удивился Беккер - Я зашел куда не следовало. - Моя просьба покажется вам безумной, - сказала она, заморгав красными глазами, - но не могли бы вы одолжить мне немного денег. Беккер посмотрел на нее в полном недоумении. - Зачем вам деньги? - спросил .
