Check it out! A 9th Grader in United States wants to know, "how many neurons are in the brain?"
Here's an answer:
No one has counted, and there is bound to be some difference between people, but roughly 1-200 billion neurons are in your brain. Read More
Your brain is very very complicated. The complexity of your thoughts is not totally dictated by how many neurons you have, because how they connect and how flexible those connections are also matters. People have tried to estimate the number of neurons and connections in a human brain, by counting small volumes and then multiplying that number up to the volume of the brain. The most common estimates are around 100 billion neurons, and 1 quadrillion connections, though 50-250 billion neurons and 0.5-50 quadrillion are tossed around as estimates too. For scale, counting 10 quadrillion connections at 1 per second, if that were possible, would take you 300 million years!
