What Happens Inside Your Brain in Just 1 Second Will Shock You

[00:00:00]Do you know what happens inside your brain in just 1 second? In a single second, your brain performs more than 100 trillion electrical calculations between nearly 86 billion neurons. These signals are firing so fast, they can travel up to 430 km per hour, fast enough to cross a football field more than five times in a single moment. At the same time, your eyes are sending around 10 million bits of visual information every second. Meanwhile, your brain is theoretically storing information equal to around 2.5 petabytes of digital memory. That is more than 2.5 million gigabytes, meaning a single human brain could hold about 20 times more information than Wikipedia itself. And while doing all of this, your brain generates around 20 watts of electrical power continuously. That is enough energy to keep a household light bulb glowing while your mind [music] is simultaneously running trillions of calculations, controlling every movement in your body, forming memories, recognizing faces, predicting outcomes, and creating conscious thought without stopping even for a millisecond.
