World Brain Day: A Celebration of Grey Matter 22 July. In the midst of summer, when we think more about the beach and ice cream than about neurons and synapses, comes a day dedicated to the most complex object in the Universe. World Brain Day is not just a date on the calendar, but a reason to pause and realize that everything we feel, think, remember, and create originates in the three-pound jelly-like organ between our ears. It is the center of our personality, our command center, our main mystery. And perhaps the only object that tries to understand itself. Where Did This Day Come From: The Birth of the Idea World Brain Day was established in 2014 by the World Federation of Neurology (WFN). The idea was to draw attention to brain health, the prevention of neurological diseases, and the importance of scientific research. But it soon became clear that this day went far beyond medical conferences. It turned into a festival of curiosity, a day to ponder what makes us human. In 2024 and 2025, the theme of the day was dedicated to the prevention of dementia and strokes, as well as the connection between the brain and physical activity. But regardless of the theme, the essence remains: we must know more about what's in our heads. The Brain and Its Superpowers: Numbers That Astound If the brain were a computer, it would be the most powerful in history. It contains about 86 billion neurons, and each can have up to 10,000 connections with other neurons. The total number of synapses is about 100 trillion. This is more than the number of stars in the Milky Way. The brain consumes about 20% of the body's energy, although it makes up only 2% of the body's mass. It works around the clock, even when we sleep, creating dreams, processing information, and cleansing toxins. Every minute, about 400 liters of blood pass through the brain. And the speed of signal transmission through nerve fibers can reach 430 kilometers per hour. But the most amazing thing is the plasticity of the br ... Read more
