In this section we will introduce Circuit-Tool by means of an example. We will
use Circuit-Tool to construct a model which consists of three ``columns'' or
pools how they are called in Circuit-Tool . The first pool consists of
leaky integrate an fire neurons, the second is made up of sigmoidal
neurons and the third uses more detailed conductance based model
neurons. The pools will be connected internally and to each other (for
details see below). The circuit will be driven by two input spike
trains and an analog input current. The input projects in some kind of
topographic map into the circuit.
