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.

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.

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.

The Human Brain: Anatomy and Function

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. The central nervous system CNS is composed of the brain and spinal cord.

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.

Brain Overview

The occipital lobe is the part of the human brain responsible for interpreting information from the eyes and turning it into the world as a person sees it. The occipital lobe has four different sections, each of which is responsible for different visual functions. Disorder in the occipital lobe may cause disorder in the vision or the brain itself.

The Frontal Lobes are located in the front of the brain. They are very large and have many functions. The frontal lobes are considered to be our emotional control centre. They play a central role in our personality and how we act. They are also involved in attention skills and controlling movement.

Он бросил быстрый взгляд на Сьюзан, которая по-прежнему сидела на стуле, обхватив голову руками и целиком уйдя в. Фонтейн не мог понять, в чем дело, но, какими бы ни были причины ее состояния, выяснять это сейчас не было времени. - Нужно решать, сэр! - требовал Джабба.  - Немедленно. Фонтейн поднял голову и произнес с ледяным спокойствием: - Вот мое решение.
