10 Science Facts about the Human Brain, Did You Know?


Brain humans have billions of neurons or nerve cells that can communicate in trillions of connections called synapses. The brain is not only the most important organ, but also the most magical organ because it holds the power that humans can use.

Unfortunately, some people think of the brain as just the center of thought, a vital part of the organ, without studying it further.

Quoted from the official site Northwestern Medicinethere are some interesting science facts about the brain to know.

10 Science Facts About Brain Man:

1. Brain Size Doesn’t Always Imply Intelligence

Brain size is 3 pounds or about 1.3 kg. Men tend to have larger brains than women. However, brain size does not always imply intelligence.

2. Sixty Percent of the Human Brain Is Made of Fat

With this amount of fat, the brain is the fattest organ in the human body. However, these fatty acids are very important for brain performance.

3. The brain is not fully formed until the age of 25

The age of 25 years may have entered the stage of an adult human. But in fact, the brain is not fully formed at this age.

To note, brain development starts from the back of the brain and goes to the front. Therefore, the frontal lobe, which controls planning and reasoning, is the last part of the brain to strengthen and make connections.

4. Almost Unlimited Brain Storage Capacity

Research shows the human brain consists of about 86 billion neurons. Each neuron forms connections to other neurons, which can number up to 1 quadrillion (1,000 trillion) connections.

Over time, these neurons can merge, increasing storage capacity. However, in Alzheimer’s disease, for example, many neurons can be damaged and stop working, especially affecting memory.

5. The Importance of the Spinal Cord for the Brain

The spinal cord is the main source of communication between the body and the brain. ALS or amyotrophic lateral sclerosis, causes neurons in the brain and spinal cord to die, affecting controlled muscle movement.

Another disease that affects the brain and spinal cord is multiple sclerosis (MS). In MS, the immune system attacks the protective covering covering nerve fibers, causing communication problems between the brain and the body.

6. The brain is always active

The notion that humans only use 10 percent of the brain is a myth. Neuroscientists claim that the brain is always active, even while sleeping. So, experts emphasize that humans can really use all of their brain capacity.

7. The Brain Can ‘Freeze’

Brain freeze actually is ganglioneuralgia sphenopalatina. This pain occurs when cold hits receptors in the outer layer of the brain, which are called meninges. The cold creates dilation and contraction of the arteries, causing an instant headache.

8. A Piece of Brain Tissue The Size of a Sand Grain

Although very small, but a piece of brain tissue contains 100,000 neurons and 1 billion synapses. Damage to these neurons can have a big impact.

During a stroke, for example, blood is unable to deliver oxygen to the brain. As a result, brain cells can die, and abilities in certain brain areas can be lost.

The same goes for people with Parkinson’s disease. This disease occurs when cells in a part of the brain called the substantia nigra begin to die. As a result, body movements can be affected, including tremors, quoted from the NHS page.

9. The human brain can produce about 23 watts of power

The power is enough to light a light bulb. However, all that power requires a much-needed rest.

Adequate sleep helps maintain pathways in the brain. In addition, sleep deprivation can increase the buildup of proteins in the brain associated with Alzheimer’s disease.

10. Brain Information Moves up to 431.3 Km per Hour

It is so fast that, when stimulated, neurons generate electrical impulses that travel from cell to cell. Therefore, interruptions in this regular processing can lead to epileptic seizures.

Well, that’s some science facts about brain what you need to know. Hopefully it will add to the insights of detikers, okay!
