Your brain—it controls all of your mental functions and physical functions, whether you’re aware of it or not. It is a powerful supercomputer that science is still learning about, and will literally blow your…well, mind when you look more closely at its capabilities.
While scientists are making strides in understanding how different parts of the brain fire to control certain functions, there’s still a lot about our minds that are a mystery. Let’s take a look at nine fascinating facts about the human brain…
1. There are Trillions of Synapses
A synapse is basically brain neurons (nerve cells) communicating with one another via electrical or chemical signals. Human-Memory.net has some staggering figures relating to this topic. The source notes the average human brain contains about 100 billion neurons that can be connected to up to 10,000 other neurons (other sources present varying numbers of neurons, but the numbers are still crazy).
When you do the math based on info from Human-Memory.net, there are as many as 1,000 trillion synaptic connections, “equivalent by some estimates to a computer with a 1 trillion bit per second processor,” explains the site. For some context, modern home computers can perform at 4 GHz or higher, which is 4,000 million cycles per second. A trillion is a million times a million. Does your head hurt yet?
