The neocortex contains some 100 billion cells, each with 1,000 to 10,000 synapses (connections), and has roughly 100 million meters of wiring, all packed into a structure the size and thickness of a formal dinner napkin. The millions of nerve cells ( neurons ) in the cortex influence most of what is thought , felt, and done.
