The Gate Theory of Pain Revisited: Modeling Different Pain Conditions with a Parsimonious Neurocomputational Model

Table 3

Output of CT neuron, , for each of the input pairs in the standard gate operation calculated from stability weights and thresholds represented in Figure 12(a): Net₁ is obtained applying (2). In this case Net₁ is calculated as Net₁ = for each pair. Neuron 1 output, , is equal to 1 when Net₁ is higher than its threshold, . Net₂ is calculated having into account neuron 1 inhibitory output: Net₂ = . Finally the pain signal relayed to the brain from neuron 2 is triggered when Net₂ > .
