Human Brain: Facts, Functions & Anatomy
The anatomy of the brain is complex due its intricate structure and function. This amazing organ acts as a control center by receiving, interpreting, and directing sensory information throughout the body.
The brain and spinal cord are the two main structures of the central nervous system. There are three major divisions of the brain.
They are the forebrain, the midbrain, and the hindbrain. The forebrain is the division of the brain that is responsible for a variety of functions including receiving and processing sensory information, thinking, perceiving, producing and understanding language, and controlling motor function.
There are two major divisions of forebrain: the diencephalon and the telencephalon. The diencephalon contains structures such as the thalamus and hypothalamus which are responsible for such functions as motor control, relaying sensory information, and controlling autonomic functions.
The telencephalon contains the largest part of the brain, the cerebrum. Most of the actual information processing in the brain takes place in the cerebral cortex. The midbrain and the hindbrain together make up the brainstem. The midbrain or mesencephalon , is the portion of the brainstem that connects the hindbrain and the forebrain. This region of the brain is involved in auditory and visual responses as well as motor function. The hindbrain extends from the spinal cord and is composed of the metencephalon and myelencephalon.
The metencephalon contains structures such as the pons and cerebellum. These regions assists in maintaining balance and equilibrium, movement coordination, and the conduction of sensory information. The myelencephalon is composed of the medulla oblongata which is responsible for controlling such autonomic functions as breathing, heart rate, and digestion. The brain contains various structures that have a multitude of functions. Below is a list of major structures of the brain and some of their functions.

Key Takeaways The forebrain, the midbrain, and the hindbrain are the three main parts of the brain. The forebrain has two major parts called the diencephalon and the telencephalon. The forebrain is responsible for a number of functions related to thinking, perceiving, and evaluating sensory information. The midbrain, also called the mesencephalon, connects the hindbrain and the forebrain. It is associated with motor functions and auditory and visual responses. The hindbrain contains both the metencephalon and the myelencephalon.
The hindbrain is associated with balance and equilibrium and the coordination of movement along with autonomic functions like our breathing and our heart rate.

Understanding Brain, Mind and Soul: Contributions from Neurology and Neurosurgery
Charles A. He has conducted research on typically developing infants and children and children who have experienced early biological and psychosocial adversity. Research over the past several decades has provided insight into the processes that govern early brain development and how those processes contribute to behavior. In the following article, we provide an overview of early brain development beginning with a summary of the prenatal period. We then turn to postnatal development and examine how brain functions are built and how experience mediates this process. Specifically, we discuss findings from research on speech and on face processing. The results of this research highlight how the first few years of life are a particularly important period of development of the brain.

As the popular press has discovered, people have a keen appetite for research information about how the brain works and how thought processes develop Newsweek, , ; Time, a, b. Interest runs particularly high in stories about the neuro-development of babies and children and the effect of early experiences on learning. The fields of neuroscience and cognitive science are helping to satisfy this fundamental curiosity about how people think and learn.
The brain is a fascinating and complex organ. It is responsible for senses, movement and control, emotions and feelings, language and communication, thinking and memory. Research of the brain and understanding the inner workings of the brain will help us to learn about the mechanisms of certain neurological conditions, including hydrocephalus. Increasing our own knowledge of the brain helps us understand our own bodies better and helps us have informed conversations with our doctors, be it as a patient or a caregiver. To celebrate BAW we present a two-part blog to increase our understanding of the brain and how the brain is impacted by hydrocephalus.

Anatomy of the Brain
A brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It is located in the head , usually close to the sensory organs for senses such as vision. It is the most complex organ in a vertebrate's body.
Deshmukh Marg, Mumbai, Treatment of diseases of the brain by drugs or surgery necessitates an understanding of its structure and functions. The philosophical neurosurgeon soon encounters difficulties when localising the abstract concepts of mind and soul within the tangible gram organ containing billion neurones. Hippocrates had focused attention on the brain as the seat of the mind. Experiences gained from accidental injuries Phineas Gage or temporal lobe resection William Beecher Scoville ; studies on how we see and hear and more recent data from functional magnetic resonance studies have made us aware of the extensive network of neurones in the cerebral hemispheres that subserve the functions of the mind. The soul or atman, credited with the ability to enliven the body, was located by ancient anatomists and philosophers in the lungs or heart, in the pineal gland Descartes , and generally in the brain. When the deeper parts of the brain came within the reach of neurosurgeons, the brainstem proved exceptionally delicate and vulnerable.

Form and function of nervous systems
Nervous system , organized group of cells specialized for the conduction of electrochemical stimuli from sensory receptors through a network to the site at which a response occurs. All living organisms are able to detect changes within themselves and in their environments. Changes in the external environment include those of light , temperature , sound , motion, and odour , while changes in the internal environment include those in the position of the head and limbs as well as in the internal organs. Once detected, these internal and external changes must be analyzed and acted upon in order to survive. As life on Earth evolved and the environment became more complex, the survival of organisms depended upon how well they could respond to changes in their surroundings. One factor necessary for survival was a speedy reaction or response.
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 outermost layer of the cerebrum is the cerebral cortex, which consists of four lobes: the frontal, parietal, temporal and occipital. Like all vertebrate brains, the human brain develops from three sections known as the forebrain, midbrain and hindbrain.
Единственная беда - Халохот глухой, с ним нельзя связаться по телефону. Недавно Стратмор сделал так, что Халохота снабдили новейшей игрушкой АНБ - компьютером Монокль. Себе Стратмор купил Скайпейджер, который запрограммировал на ту же частоту. Начиная с этого момента его связь с Халохотом стала не только мгновенной, но и абсолютно неотслеживаемой. Первое послание, которое он отправил Халохоту, не оставляло места сомнениям, тем более что они это уже обсуждали: убить Энсея Танкадо и захватить пароль.
Может. - Сьюзан пожала плечами, демонстрируя равнодушие. - Мы с ним какое-то время переписывались, - как бы невзначай сказал Хейл.
Она опустилась на стул. - В четыре сорок пять ко мне на личный телефон поступил звонок. Вы можете сказать, откуда звонили? - Он проклинал себя за то, что не выяснил этого раньше. Телефонистка нервно проглотила слюну. - На этой машине нет автоматического определителя номера, сэр.
Шаги быстро приближались. Беккер еще сильнее вцепился во внутреннюю часть проема и оттолкнулся ногами. Тело налилось свинцовой тяжестью, словно кто-то изо всех сил тянул его .
Вы его убили! - крикнула. - Вы его убили! - Она бросилась к экрану, протянула к нему руки. - Дэвид… Все пришли в смятение.
Она не помнила, чтобы это слово срывалось когда-нибудь с губ коммандера Стратмора. Чрезвычайная. В шифровалке. Она не могла себе этого представить. - С-слушаюсь, сэр.
