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.

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.
It also integrates sensory impulses and information to form perceptions, thoughts, and memories. The brain gives us self-awareness and the ability to speak and move in the world. Its four major regions make this possible: The cerebrum , with its cerebral cortex, gives us conscious control of our actions. The diencephalon mediates sensations, manages emotions, and commands whole internal systems. The cerebellum adjusts body movements, speech coordination, and balance, while the brain stem relays signals from the spinal cord and directs basic internal functions and reflexes. The cerebrum is the largest brain structure and part of the forebrain or prosencephalon. Its prominent outer portion, the cerebral cortex, not only processes sensory and motor information but enables consciousness, our ability to consider ourselves and the outside world.
The human brain is the central organ of the human nervous system , and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum , the brainstem and the cerebellum. It controls most of the activities of the body , processing, integrating, and coordinating the information it receives from the sense organs , and making decisions as to the instructions sent to the rest of the body. The brain is contained in, and protected by, the skull bones of the head. The cerebrum is the largest part of the human brain. It is divided into two cerebral hemispheres. The cerebral cortex is an outer layer of grey matter , covering the core of white matter.
and works down into the specifics of brain anatomy. The average weight of an adult human brain is about each hemisphere performs its own functions in.
Although we now know that most brain functions rely on many different regions across the entire brain working in conjunction, it is still true that each lobe carries out the bulk of certain functions. In humans, the lobes of the brain are divided by a number of bumps and grooves. These are known as gyri bumps and sulci groves or fissures. The folding of the brain, and the resulting gyri and sulci, increases its surface area and enables more cerebral cortex matter to fit inside the skull.

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 brain controls our thoughts, memory and speech, movement of the arms and legs, and the function of many organs within our body.

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.
Хейл побледнел. - Что это. - Стратмор только сделал вид, что звонил по телефону.
Он убил Дэвида. Бринкерхофф положил руку ей на плечо. - Мы почти приехали, мисс Флетчер. Держитесь.
Она понимала, что это больше не имеет значения: Хейл и без того знал все, что можно было знать. Мне нужно доложить об этом Стратмору, - подумала она, - и как можно скорее. ГЛАВА 38 Хейл остановился в центре комнаты и пристально посмотрел на Сьюзан. - Что случилось, Сью.
