Each neuron has up to 40,000 connections with other neurons, and
there are more than 30 billion (not million) of them in a human brain

Each neuron has up to 40,000 connections with other neurons, and there are more than 30 billion (not million) of them in a human brainweighing approximately 3 1/2 pounds. As complex and miniaturized as it already is, and considering that the interaction of genetics and experience has endowed each brain with a unique (although similar) connection pattern, the difficulties involved in further shrinking them
are daunting, to say the least. Joe
