The basic computational unit of our brains is called a neuron, and we have approximately 86 billion neurons in our nervous system, which are connected with approximately 
to 
synapses.
Figure 1 shows a biological neuron. Figure 2 shows the corresponding mathematical model. In the drawing of the biological neuron, each neuron receives incoming signals from its dendrites and then produces output signals along its axon, where the axon gets split out and connects via synapses to other neurons.
In the corresponding ...
