Amazing Human Brain…

The human brain is the most complex organ in the human body.  The complexity of the human brain acts as a storage device that safely stores your most precious memories.  A person’s personality is largely shaped by the brain as well as by the human consciousness which gives man passion, movement, and emotion.

It helps us think, reason, remember and learn new things.  In fact, our brain and its primary function are different from animals.

**MOST INTERESTEING FACTS ABOUT THE BRAIN**

• There are 100 billion neurons in the brain.

• The blood vessels in the brain are nearly 160,000 kilometers long.

• Almost 80% of the brain is water.  Therefore, if we are dehydrated, it affects our memory and concentration.

• When you are awake, your brain generates about 25 watts of energy, which is enough to light up a light bulb.

• It is only around the age of 25 that the human brain reaches full maturity.

• The human brain weighs about 1.5 kg, which is just 2% of body weight.

• Albert Einstein’s brain weighed 1,230 grams and the French writer, Nobel Prize winner Anatole France, had a brain weighing 1 kg – bigger is not always better.

• Statistically, the male brain is 10% larger than the female brain (in proportion to body size).  However, this is not accompanied by a difference in efficiency.  Interestingly, the hippocampus, which is responsible for memory, is usually larger in women.

• The speed of the nerve impulse is about 400 km / h.

• On average, every day a person experiences about 70,000 thoughts, about 70% of which are pessimistic and self-critical.

• 90% of decisions are made subconsciously.

• The amount of information reaching our brain is approximately 100 megabytes per second.

• Drinking alcohol does not make him forget about things and events.  When you drink, your brain temporarily loses its ability to form memories, so there is nothing to forget.

• About 25% of a person’s cholesterol is found in the brain.

• One-third of the entire brain deals with the processing of visual stimuli.

• Epilepsy is a type of “short circuit” that occurs in the brain.  This is the only state in which the brain is almost 100% active.

• The human brain is incredibly plastic.  If one area of ​​the brain is damaged, another can take over its functions.

• Physical activity and movement are just as important for the brain as it is for the rest of the body.  They can delay Alzheimer’s disease by up to 30% as they make blood flow to the brain more regular.

• Music triggers activity in the same part of the brain that releases dopamine during sex and eating.

• The fact that we only use 10% of our brain is a myth.  Each part of the brain is assigned a specific function.  The truth is that we can use its capabilities much better.  Our brain has great potential, and we can learn to use it more effectively.

• The more we stimulate the brain to work, the better it works.  An active brain is more resistant to aging and Alzheimer’s.

• Here are some interesting facts about the human brain:

• The brain can survive 5 to 6 minutes when it is not getting oxygen, then it dies.

• The brain’s storage capacity is virtually limitless.  It does not “use up” like your computer’s RAM.  Recent research shows that the brain’s memory capacity is about as much as needed to store the entire Internet.

• The scientists involved in the AI ​​Impacts project have developed a way to compare supercomputers to the brain – measuring how fast a computer can move information within its own system.  According to this standard, the human brain is 30 times more powerful than the IBM Sequoia, one of the fastest supercomputers in the world.

• There are nearly 200 known cognitive disorders and distortions that cause irrational thinking and acting.

• Memories are shockingly incredible and change over time.  Emotions, motivation, cues, context, and frequency of use can all influence how accurately you remember something.

• The human brain is the only organ in the human body that lacks nerves, even though it functions as the central nervous system.  It simply means that the human brain does not feel pain.

• Many people believe that people use less than 10% of their brain.  This is a misconception because every part of the brain has a known function.

• The neocortex is the part of the human brain responsible for language and consciousness.  It accounts for approximately 76% of the human brain.

• The brain processes information at a speed of 0.5 m / s to even 120 m / s per second.

• There is no doubt that the human brain is an utterly amazing organ that requires maximum care to maintain life processes.

• The brain is 73% water.  Only 2% of dehydration affects attention, memory, and other cognitive skills.

• Human brain tissue is not dense.  It is very delicate – soft and like the consistency of soft tofu or gelatin.

• The brain makes half a cup of fluid every day.  They float in this cerebrospinal fluid bath that acts as a shock absorber, preventing the brain from being crushed by its own weight.

• It is estimated that out of thousands of thoughts that a person has every day, 70% of this mental energy is negative – self-critical, pessimistic.

• You will feel more relax, focus and creativity by meditating for 12 minutes a day.

• 28.90% of decisions are made in the subconscious mind.

• It consists of 60% fat and is one of the fattiest organs in the human body.

• Of the total amount of blood and oxygen that is produced in our body, the brain receives 20% of this amount.

• When the blood supply to the brain stops, it begins to pass out after almost 8-10 seconds. Some scientists think it is possible that a mutant virus or parasite can invade the brain and spread rapidly in large populations, causing a “zombie apocalypse”.

• Each minute, 750 to 1000 milliliters of blood flows through the brain.

• Your brain can process the image your eyes saw for as little as 13 milliseconds – less time than blinking.

• Size matters in some things, but with the brain, bigger does not always mean better or smarter.

• Albert Einstein’s brain weighed 1230 grams – 10% less than the average weight.  The brain of the Neanderthals was 10% larger than our Homo sapiens brain.

• Overall, the male brain is 10% larger than that of the female, even after accounting for the larger body size.  However, the hippocampus, the part of the brain most closely related to memory, is typically larger in women.

• Good nutrition is crucial to the health and function of the brain.  Diet can force the brain to eat on its own.  Malnourished fetuses and infants suffer from cognitive and behavioral disorders, slower motor and language development, and a lower IQ.  Babies consume nearly 50% of their total glucose supply, which may be one reason babies sleep so much.

• Drugs and alcohol interfere with the mechanisms of the brain and have some effects on dopamine and the opioid systems that give us a sense of pleasure and reward.

• The reaction to alcohol takes only 6 minutes.  And drinking alcohol does not make you forget about things and events.  When you drink, your brain temporarily loses its ability to form memories.

• The blood vessels present in the brain are nearly 99.4 miles (160,000 kilometers) long.

• When active, the brain generates about 25 watts of energy – enough to light a light bulb.

• The human brain is incredibly plastic.  If one area of ​​the brain is damaged, another can take over its functions.

• The brain does not feel pain.  Tissues innervated by pain are external to him.

• Thinking is electricity and chemistry.  Neurotransmitters, which are released from synapses, are designed to chemically excite other neurons.  The electrical impulse passes through the excited neuron and releases neurotransmitters at the end of it.  In this way, information is transferred between the neurons, making it possible for the brain to function properly.

• During sleep, the brain works by sorting out the information it has gathered during the day.

• One-third of the entire brain deals with the processing of visual stimuli.

• Epilepsy is a type of “short circuit” that occurs in the brain.  This is the only state in which the brain is 100% active.

• Einstein’s brain in the area that is responsible for math and spatial perception was 35% larger than that of average people.

• The fact that we only use 10% of our brain is not true.  Always and everywhere we use our entire brain, each part of it has a function assigned to it.  It is true, however, that we can use that 100% much better.

• The claim that the hemispheres dominate is also incorrect.  In fact, the left one is responsible for logic and rationality, and the right one is responsible for intuition, spontaneity, and emotions.  However, most activities involve both equally, and their cooperation is imperative.

• The amount of information reaching our brain is approximately 100 megabytes per second.
