"you are born with over 16trillion brain cells."
Another answer that appears to be wildly off the mark. Amazing what a huge variation I'm finding on this one.
The consensus seems to be around the 100 billion mark:

About one hundred billion (100,000,000,000)
There are over 400,094,800 cells in the human brain, while the entire body has about 50 to 75 trillion cells.
There are approximately 100 billion neurons inside a human brain.
There is about 160,000,000,000 cells in human brain. Half of the number are neurons, which are rensponsible for all the "thinking" functions. The other half are "glial cells", which help neurons with their activity.
There are about 86 billion neurons in the human brain. That's about half the estimated number of stars in our Milky Way galaxy.
There are 100 billion neurons in th human brain and about 1-5 trillion glial cells (that's 10-50 times more!). Most are astrocytes.
lthere are 10 billion nerve cells in human brain, they are called as Neurons. Each Neuron is the functional unit of nervous system.
