a normal mature person has about 14 - 17 billion cells in his brain. The number will gradually decrease as he gets older

Well, it's more than billions
Problem 1: differet humans have different number of cells
If the brain is like Albert Einstien which is so big, I'm sure it's trillions.
If it's like our brain ( normal ) maybe it's billions.
