Write some interesting facts about human brain.​

Answer 1

Interesting facts about human brain :-

1. Sixty percent of the human brain is made of fat. Not only does that make it the fattiest organ in the human body, but these fatty acids are crucial for your brain’s performance. Make sure you’re fueling it appropriately with healthy, brain-boosting nutrients.
2. Your brain isn't fully formed until age 25. Brain development begins from the back of the brain and works its way to the front. Therefore, your frontal lobes, which control planning and reasoning, are the last to strengthen and structure connections.
3. Your brain’s storage capacity is considered virtually unlimited. Research suggests the human brain consists of about 86 billion neurons. Each neuron forms connections to other neurons, which could add up to 1 quadrillion (1,000 trillion) connections. Over time, these neurons can combine, increasing storage capacity. However, in Alzheimer’s disease, for example, many neurons can become damaged and stop working, particularly affecting memory.
4. Brain information travels up to an impressive 268 miles per hour. When a neuron is stimulated, it generates an electrical impulse that travels from cell to cell. A disruption in this regular processing can cause an epileptic seizure.
5. On average, your spinal cord stops growing at 4 years old. Your spinal cord, which consists of a bundle of nervous tissue and support cells, is responsible for sending messages from your brain throughout your body.
6. The spinal cord is the main source of communication between the body and the brain. ALS, or amyotrophic lateral sclerosis, causes the neurons in the brain and spinal cord to die, impacting controlled muscle movement. Another disease that affects both the brain and the spinal cord is multiple sclerosis (MS). In MS, the immune system attacks the protective layer that covers nerve fibers, causing communication problems between the brain and the body.
7. It’s a myth that you only use 10 percent of your brain. You actually use all of it. (Yes, even when you are sleeping.) Neurologists confirm that your brain is always active.
8. The human brain weighs 3 pounds. (That’s about as much as a half-gallon of milk.) However, size does not always imply intelligence. Men tend to have larger brains than women.
9. A brain freeze is really a sphenopalatine ganglioneuralgia. This pain occurs when cold hits the receptors in the outer covering of the brain, called the meninges. The cold creates a dilation and contraction of arteries, causing a rapid-onset headache.
10. A piece of brain tissue the size of a grain of sand contains 100,000 neurons and 1 billion synapses. However, damage to neurons can have great impact. During a stroke, for example, blood is not able to get oxygen to the brain. As a result, brain cells can die, and abilities in that particular area of the brain can be lost. Similarly, Parkinson’s diseaseoccurs when the cells of a part of your brain called the substantia nigra start to die.
11. The human brain can generate about 23 watts of power (enough to power a lightbulb). All that power calls for some much-needed rest. Adequate sleep helps maintain the pathways in your brain. Additionally, sleep deprivation can increase the build-up of a protein in your brain that is linked to Alzheimer’s disease.

Explanation:

How the brain works,

The brain is part of your body’s central nervous system. It’s the most complicated part of your body. It has the ability to send and receive an enormous amount of information. Because it is so complex, there are some things doctors and scientists don’t completely understand yet about it. This also means that there are some amazing things you may not know about your brain.

Interesting Facts :-

• signs of successful brain surgeries go as far back as the Stone Age.

• An adult brain weighs about 3 pounds.

• About 75 percent of the brain is made up of water. This means that dehydration, even in small amounts, can have a negative effect on the brain functions.

• the largest brain of any animal is that of the sperm whale. It weighs about 20 pounds.

• The human brain will grow three times its size in the first year of life. It continues to grow until you’re about 18 years old.

• Headaches are caused by a chemical reaction in your brain combined with the muscles and nerves of your neck and head.

• The brain of a human contains approximately one hundred billion neurons

• It is a myth that humans only use 10 percent of our brain. We actually use all of it. We’re even using more than 10 percent when we sleep.

• Cholesterol is key to learning and memory. However, high cholesterol has different effects depending on your age and other factors.

• Information runs between neurons in your brain for everything we see, think, or do. These neurons move information at different speeds. The fastest speed for information to pass between neurons is about 250 mph.

•  Dreams are believed to be a combination of imagination, phycological factors, and neurological factors. They prove that your brain is working even when you are sleeping.

• Phantom limb pain syndrome is when the central nervous system, which includes your brain, continues to feel the pain of a limb that has been amputated.

• The brain can’t feel pain. It interprets pain signals sent to it, but it does not feel pain.

• A brain freeze is really a sphenopalatine ganglioneuralgia. It happens when something you eat or drink something that’s cold. It chills the blood vessels and arteries in the very back of the throat, including the ones that take blood to your brain. These constrict when they’re cold and open back up with they’re warm again, causing the pain in your forehead.

• The human brain begins to lose some memory abilities as well as some cognitive skills by your late 20s.
