How many brain cells does an average person have?

Our brains contains about 100 billion microscopic cells called neurons. There are so many, it would take you over 3,000 years to count them all!

Your brain generates enough electricity to power a lightbulb

Your brain contains about 100 billion microscopic cells called neurons. There are so many, it would take you over 3,000 years to count them all! Whenever you dream, laugh, think, see or move, it’s because minute chemical and electrical signals are racing between these neurons along billions of tiny neuron pathways. Incredibly, the activity in your brain never stops. Countless messages zip around inside it every second – just like a supercharged pinball machine. Your neurons create and send more messages than all the phones in the entire world. And while a single neuron generates only a very small amount of electricity, all your neurons together can produce enough energy to power a low-wattage light bulb. Imagine that!
