it's the organ that makes us human, giving people the capacity for art, language, moral judgments, and rational thought.

It's also responsible for each individual's personality, memories, movements, and how we sense the world.
-
All this comes from a jellylike mass of fat and protein weighing about 3 pounds (1.4 kilograms). It is, nevertheless, one of the body's biggest organs, consisting of some 100 billion nerve cells that not only put together thoughts and highly coordinated physical actions but regulate our unconscious body processes, such as digestion and breathing.

The brain's nerve cells are known as neurons, which make up the organ's so-called "gray matter.

-
It's the cerebrum that makes the human brain—and therefore humans—so formidable.
-
Whereas animals such as elephants, dolphins, and whales have larger brains, humans have the most developed cerebrum.
-
The cerebrum has two halves, or hemispheres. It is further divided into four regions, or lobes, in each hemisphere. The frontal lobes, located behind the forehead, are involved with speech, thought, learning, emotion, and movement.
-
Behind them are the parietal lobes, which process sensory information such as touch, temperature, and pain.
-
occipital lobes, dealing with vision.
-
At the rear of the brain are the

Lastly, there are the temporal lobes, near the temples, which are involved with hearing and memory.

cerebellum, which sits beneath the back of the cerebrum. It is responsible for coordinating muscle movement and controlling our balance.

thalamus and hypothalamus. The thalamus acts as a relay station for incoming nerve impulses from around the body that are then forwarded to the appropriate brain region for processing

hese hormones govern growth and instinctual behavior such as eating, drinking, sex, anger, and reproduction. The hypothalamus, for instance, controls when a new mother starts to lactate.

The brain is extremely sensitive and delicate, and so requires maximum protection.

The spaces between these membranes are filled with fluid that cushions the brain and keeps it from being damaged by contact with the inside of the skull.

The cerebrum is the largest part of the brain, accounting for 85 percent of the organ's weight. The distinctive, deeply wrinkled outer surface is the cerebral cortex, which consists of gray matter.

-
The brain's nerve cells are known as neurons, which make up the organ's so-called "gray matter." The neurons transmit and gather electrochemical signals that are communicated via a network of millions of nerve fibers called dendrites and axons. These are the brain's "white matter."
-
Beneath this lies the white matter. It's the cerebrum that makes the human brain—and therefore humans—so formidable. Whereas animals such as elephants, dolphins, and whales have larger brains, humans have the most developed cerebrum.
-
The second largest part of the brain is the cerebellum, which sits beneath the back of the cerebrum.
-
Consisting of both grey and white matter, the cerebellum transmits information to the spinal cord and other parts of the brain.
-
The diencephalon is located in the core of the brain. A complex of structures roughly the size of an apricot, the two major sections are the thalamus and hypothalamus.
-
The brain stem, at the organ's base, controls reflexes and crucial, basic life functions such as heart rate, breathing, and blood pressure. It also regulates when you feel sleepy or awake.
