September 28, Alex Mit Shutterstock The human brain is the command center for the human nervous system.
It plays a role in just about every major body system. Some of its main functions include: 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 frontal lobes are the largest of the lobes.
They coordinates high-level behaviors, such as motor skills, problem solving, judgment, planning, and attention. The frontal lobes also manage emotions and impulse control.
The parietal lobes are located behind the frontal lobes. The temporal lobes are located on either side of the head on the same level as the ears. They coordinate specific functions, including visual memory such as facial recognitionverbal memory such as understanding languageand interpreting the emotions and reactions of others.
The occipital lobes are located in the back of the brain. Cerebellum The cerebellum is located in the back of the brain, just below the occipital lobes. It also helps the body maintain its posture, equilibrium, and balance.The scientific study of the brain and nervous system is called neuroscience or neurobiology.
Because the field of neuroscience is so vast -- and the brain and nervous system are so complex -- this article will start with the basics and give you an overview of this complicated organ.
Summary: The Brain. The human nervous system, with its billions of nerve cells, is often described as "the most complex system in the known universe." It starts as a tube of cells in the embryo, rapidly developing three distinct parts called the forebrain, midbrain, and hindbrain.
As the forebrain develops, it folds into wrinkles called convolutions. The adult human brain weighs on average about – kg (– lb) which is about 2% of the total body weight, with a volume of around cm 3 in men and cm 3 in women, although there is substantial individual variation.
structure and function of the human brain The brain has three main parts, the cerebrum, the cerebellum, and the brain stem. The brain is divided into regions that control specific functions.
The science of early brain development can inform investments in early childhood. These basic concepts, established over decades of neuroscience and behavioral research, help illustrate why child development—particularly from birth to five years—is a foundation .
The human brain has the same basic structure as other mammal brains, but is larger in relation to body size than any other brains. Facts about the human brain The human brain is the largest brain.
