THANKS FOR THE TOP



PLEASE wait until the post is totally loaded because it have a lot of cool stuff


Hi, welcome to my new post.

Information about the Brain


Making sense of the brain's mind-boggling complexity isn't easy. What we do know is that 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." The neurons transmit and gather electrochemical signals that are communicated via a network of millions of nerve fibers called dendritesand axons. These are the brain's "white matter."
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. 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. It's packed to capacity inside our skulls, enveloping the rest of the brain, with the deep folds cleverly maximizing the cortex area.
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. At the rear of the brain are the occipital lobes, dealing with vision. Lastly, there are the temporal lobes, near the temples, which are involved with hearing and memory.
Movement and Balance

The second largest part of the brain is the cerebellum, which sits beneath the back of the cerebrum. It is responsible for coordinating muscle movement and controlling our balance. 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 andhypothalamus. 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. The hypothalamus controls hormone secretions from the nearby pituitary gland. These 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 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.
The brain is extremely sensitive and delicate, and so requires maximum protection. This is provided by the surrounding skull and three tough membranes called meninges. 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.

Facts
1. The brain consumes about 17 percent of the body’s total energy but accounts for only 3 percent of bodyweight.
The forebrain, located in the forward region of the brain, is responsible for intellectual functions such as planning, problem-solving and logic.

2. The human brain consists of some 100 billion active nerve cells.

3. The brain’s neurons communicate by transmitting electrical impulses along their axons. Interactions among neurons can be simple or complex, and the amount of time they take can range from milliseconds to months.

4. After about three weeks of gestation, a human fetus’s brain begins to form. By the fourth week, it is identifiable.
5. There are 22 different bones in the skull, eight in the cranium and 14 in the face.

6. Basic life functions such as breathing, blood flow and heartbeat are controlled by the brain stem, located at the brain’s base.

7. The cerebrum accounts for about 85 percent of the brain’s weight and is the organ’s largest part.

8. Often referred to as the “little brain,” the cerebrum is the second-largest part of the brain. It handles muscle movement and controls balance.

9. The left hemisphere handles language, analytics and mathematical reasoning.

10. Creative, artistic and spontaneous thoughts are derived from the right hemisphere of the brain.

11. Many ancient philosophers believed that human consciousness resided in the heart. It wasn't until 17th century that philosopher Thomas Willis began to argue the vast powers of the brain.

12. Although the brain registers pain, the organ itself has no pain receptors.

13. The brain is constantly sending and receiving information. Motor circuits transmit information away from the brain to muscles and glands, while sensory circuits report findings to the brain.

14. The brain has a jellylike consistency and is made up of fat and protein.

15. The cerebrum is divided into left and right hemispheres, each with four main areas: the frontal lobe, parietal lobe, occipital lobe and temporal lobe.

16. The average adult's attention span is 20 minutes (unless it’s a topic one finds especially interesting).

17. Children’s attention spans, however, are usually close to their age in minutes.

18. Stress can interfere with the brain’s cognitive processes.

19. People who frequently suffer from jet lag can experience memory loss and even brain damage. This may be because of stress-induced hormones associated with jet lag.

20. It’s believed that playing videogames can help you multitask more efficiently.

21. Yawning may help keep you alert by expanding the pharynx and larynx, thus allowing the intake of more oxygen, which the brain needs to function properly.

22. The brain's frontal lobe may be a kind of “humor center.” Some people with damage to this area of the brain, especially on the right side, often don’t get jokes.

23. What do an adult human and a bottlenose dolphin have in common? Their brains weigh almost the same amount. An adult human brain weighs about three pounds, and a bottlenose dolphin’s brain tips the scales at about four pounds.

24. As we age, we can often remember long-ago events more easily than recent events.

25. Sleep is essential for your brain. Sleep deprivation can lead to “microsleep,” when the brain “shuts off” for a few seconds at a time. An impaired person might lose track of a conversation or task.

26. 9.5 percent of children in the United States have been diagnosed with attention deficit hyperactivity disorder (ADHD).

27. Loss of brain cells in the substantia nigra region of the brain can lead to Parkinson’s disease.

28. The ability to pay attention to one sound out of a cacophony of sound is called the "cocktail effect.”

29. The grooves and folds in the cerebral cortex are called convolutions.

30. Nerves connect all the body’s organs to the brain. Nerve impulses race to the brain as fast as 250 miles an hour.




Optical Illutions

In this optical illusion can be seen crossing black spots are white spots.

Get up and walk back and see that Einstein's face changed to Harry Potter's face.

Amazing this optical illusion, it is assumed that what you see in the picture are blue lines straight, but the illusion does not seem it causes.

At the lake  Burma  in Burma is a curious optical phenomenon once a year when the sun reflects off the rocks in the area. If you do not see it at first, turns his head left and you will clearly see a man and a child praying.
