The Frontal Lobes are located in the front of the brain.

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:.

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.

Human Brain: Facts, Functions & Anatomy

Hindbrain , also called rhombencephalon , region of the developing vertebrate brain that is composed of the medulla oblongata , the pons , and the cerebellum. The hindbrain coordinates functions that are fundamental to survival, including respiratory rhythm, motor activity, sleep , and wakefulness. It is one of the three major developmental divisions of the brain; the other two are the midbrain and forebrain. Each of the three different regions of the hindbrain helps coordinate specific functions and activities. The medulla transmits signals between the spinal cord and the higher parts of the brain; it also controls autonomic functions such as heartbeat and respiration.

The brain is a remarkably complex organ comprised of billions of interconnected neurons and glia. It is a bilateral, or two-sided, structure that can be separated into distinct lobes. Each lobe is associated with certain types of functions, but, ultimately, all of the areas of the brain interact with one another to provide the foundation for our thoughts and behaviors. It can be said that the spinal cord is what connects the brain to the outside world. Because of it, the brain can act.

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.

Brain Overview

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 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.

Неужели он ее трогает. Она не сразу поняла, что он пытается застегнуть верхнюю пуговицу ее блузки. - Сьюзан, - позвал он, задыхаясь.  - Ты должна помочь мне выбраться отсюда.

The Central Nervous System

За окном не было ничего, кроме беспросветного мрака. Шифровалка исчезла.

Но он очень толстый. Жена отказывает ему… ну, вы понимаете.  - Беккер не мог поверить, что это говорит он. Если бы Сьюзан слышала меня сейчас, - подумал.  - Я тоже толстый и одинокий.

Беккер застонал и провел рукой по волосам. - Когда он вылетает. - В два часа ночи по воскресеньям. Она сейчас наверняка уже над Атлантикой. Беккер взглянул на часы. Час сорок пять ночи. Он в недоумении посмотрел на двухцветного.

Стратмор повернулся, и Сьюзан сразу же его потеряла. В страхе она вытянула вперед руки, но коммандер куда-то исчез. Там, где только что было его плечо, оказалась черная пустота. Она шагнула вперед, но и там была та же пустота. Сигналы продолжались.


The Parietal lobes are responsible for Spatial functions. • The left Parietal lobe is responsible for spatial language (on, over, on top of, before). • The right Parietal.


 У меня нет никакого ключа. - Хватит врать! - крикнул Стратмор.  - Где .

Она попыталась высвободиться.

The frontal and the temporal areas of the brain cortex are larger in volume in women. ➢ The Amygdala is larger in males; the Hippocampus is activated on its​.
