Human brain wires, the Neurons

A good friend of mine once said "THE HUMAN BRAIN GENERATES MORE ELECTRICAL IMPULSES IN ONE DAY THAN ALL THE TELEPHONES IN THE WORLD." This is to confirm his statement. He also added "one brain.... 100 billion wires ... number of possible permutations for connections of neurons.. ... 100 billion factorial = ~ 3.75 times 10 to the power of 1,056,570,551,815..."
