A neuron is a nerve cell. The brain is made up of approximately 100 billion neurons. Neurons are similar to other cells in the body in some ways such as: Neurons are surrounded by a membrane. Neurons have a nucleus that contains genes. Neurons contain cytoplasm, mitochondria and other organelles.
the brain contains about 10^11 (100 billion) neurons. If we assume that the average neuron has 1,000 connections (not unreasonable), and that each of these connections stores one byte, then your figure of 100 terabytes is reasonable. So that's about one hundred thousand (100,000) gigabytes.
