There are different estimates (because there are literally too many to count!), but somewhere between 86 billion and 100 billion cells. And each cell has loads of connections (called synapses) to other cells, so we have billions of cells and trillions of synapses!
Interestingly, even though our brains have that many cells, there’s also a lot of research which says our brains find it difficult to imagine just how big numbers like a billion are!
