6.2 BASIC CONCEPTS OF NEURAL NETWORKS
A portion of a network composed of two cells is shown in Figure 6.2.
The cell itself includes a nucleus (the central processing portion of the neuron). To the left of cell 1,the dendrites provide input signals to the cell.
To the right, the axon sends output signals to cell 2 via the axon terminals. These axon terminals merge with the dendrites of cell 2.
Signals can be transmitted unchanged, or they can be altered by synapses. A synapse is able to increase or decrease the strength of the connection between neurons and cause excitation or inhibition of a subsequent neuron.
