The brain is one of the most important and most fascinating and complex organs in the human body. It is an incredibly plastic command center that oversees the work of the nervous system.

Brain
1
The average weight of a brain ranges from about 1,225 to 1,375 grams.
Men's brains are heavier than women's brains, but the weight does not affect the brain’s performance. An infant's brain weighs only 350 grams.
2
The human brain is made of two hemispheres separated by a longitudinal furrow
Each of the hemispheres is divided into five lobes: frontal, parietal, temporal, occipital, and marginal.
3
There are approximately 100 billion neurons in the human brain.
Most neurons are found in the cerebellum, ranging from 55 to 70 billion. The cerebral cortex, or what makes us intelligent beings, is made up of 14 to 16 billion neurons.
4
It consists of 75% water.
This is primarily why proper hydration of the body is so important - dehydration disrupts the brain’s work.
5
Even though it accounts for only 2% of body weight, it uses about 20% of the energy produced by the body.
6
The brain develops and matures until around the age of 25.
During the first year of life, an infant's brain enlarges threefold.
7
Brain cells are produced throughout life.
Until the publication of research on neurogenesis in 2018, it was assumed that the process of creating neurons ends in childhood.
8
Docosahexaenoic acid (DHA) plays a key role in the proper functioning of the brain.
It is an organic chemical compound from the group of omega-3 fatty acids, therefore the consumption of polyunsaturated fatty acids is extremely important.
9
Involving your brain in activities that involve solving logical problems reduces the likelihood of developing dementia by approximately 63%.
For health reasons, you should therefore perform as many tasks as possible involving the brain. Reading, searching for information, counting, solving puzzles, or playing games that engage the brain can pay off in the later years of our lives.
10
The brain produces about 25 watts of energy.
It does not happen that the brain does not function even for a nanosecond. It constantly analyzes, transmits and systematizes information, receives and processes stimuli. Although a single neuron generates tiny amounts of electricity, by adding up all the neurons in the brain, the energy they produce could power an LED bulb.
11
About 25% of the body's cholesterol is contained in the brain.
12
The brain requires constant supplementation with oxygen.
Cut off from oxygen, brain cells start dying after about 5 minutes.
13
There are no nerve receptors in the brain that register pain, so it does not feel it.
14
An adult brain can store the equivalent of 2.5 million gigabytes of information.
15
Sleep is essential for the proper functioning of the brain.
During sleep, the brain stores and systematizes information.
16
Physical activity is equally important for the proper functioning of the brain, as it helps to create new nerve connections.
Medium-intensity aerobic exercise is considered the most effective.
17
The brain generates up to 80,000 thoughts a day.
That's over 3,000 thoughts per hour.
18
The smallest brain mammal is the Etruscan shrew. The biggest one - the sperm whale.
The Etruscan shrew is also the smallest of the currently known mammals.
19
Thanks to the word patterns stored in memory, a person is able to read the text in which the letters have been mixed.
It is enough for the first and last letters of a word to be in the correct place.
