Rank-Order Coding principle [68].
This type of neuron encodes the rank code of an input signal. Its amplitude is translated into an ordered sequence and the neuron’s synaptic weights are associated with this sequence. In our example, the neural activity is salient to this particular order, which is seen in the line widths of the synaptic weights.
