1. A method of adjusting connection efficacy in a neuron network, comprising: based on generating an excitatory output by a neuron, (i) increasing a first efficacy of one or more inhibitory connections providing an inhibitory input to the neuron and (ii) increasing a second efficacy of one or more excitatory connections providing an excitatory output to an inhibitory neuron; and based on receiving the inhibitory input, reducing the first efficacy and reducing the second efficacy.
