Cell Recognition by Axonal Growth Cones in Vitro
The brain of a vertebrate contains, in one cubic millimeter, about 100,000 neurons. The neurons are connected with each other by fibers, the axons and dendrites. Each cubic millimeter contains about one kilometer of such fibers. The number of synapses, the sites where information can be exchanged between neurons, found within one cubic millimeter reaches 109. These are rather inconceivable numbers.
