Quantum neural nets
Your brain is made up of approximately 200 billion cells, of which about half are neurons. Figure 10.3 illustrates an interaction between two neurons.
Figure 10.3 – Communicating neurons
A neuron communicates with a neighboring neuron by sending a chemical substance (a neurotransmitter) out of its axon. The neurotransmitter leaps across a synapse – a little gap between the sending and receiving neuron. On the other side of the synapse, a dendrite receives the neurotransmitter and then forwards a signal to the receiving neuron’s soma. Receipt of this signal may cause an electrical spike inside the receiving neuron. If the receiving neuron spikes, it sends a signal along its own axon, and the process continues.
In 1943, researchers named McCulloch and Pitts [1] described an electrical device whose behavior modeled that of a neuron. An artificial neuron has variable weights, as shown in Figure 10.4.
